- Listening to in-ear headphones & playing in a band
Hello!
First off I'd like to say it's great to see such a huge community working together to figure out what can be done to not only stop hearing loss but restore it.
I'm 20 years old and have had "hearing loss" and bad tinnitus from an incident with headphones 2 months ago.
(I will attach pictures of my two identical audiograms taken a few months apart tomorrow)
I'd like to apologize for the length of this post but it's necessary for me to talk about all this because of how much hearing has been involved in my life and to get my message across to you. Please read this post all the way through and try your best to connect everything together. I bolded all the major points of what I'm typing out to give you an easier job of reading through all this. Again, I apologize for its length, but there is a lot of backstory to this and what has happened.
I've done some researching online for a month and a half and would absolutely love it if you guys could read all the way through this and read the articles included at the bottom of this post because I truly feel like I've put two and two together in a theory with a certain type of noise-induced hearing loss that many of you may have unless you were born with hearing loss/deafness.
Now many of the things I'm about to talk about in this post are all based off how I've felt these past months, connections I've made through articles I've found online, and some deep thinking about how my hearing has been every day since the incident.
My Life leading Up to My Hearing Problem
Before I get into to how I got this hearing loss/tinnitus and the symptoms I have, I'd like to talk about what I've been involved with ever since I was a wee-little boy. Music has always been a passion for me. I remember buying my first cd ever in 2nd grade, it was Linkin Park's Reanimation Remix album. I had no idea who they were but I thought the artwork was very cool so I purchased it. That's the first time I can recall from my memory that I fell in love with listening to music. Fast forward to when I'm an 8th grader. I started a band playing the drums with two other friends where we only played one show but it was something that opened up a new horizon for me. I attended my first ever rock concert, it was a Wolfmother show, with a few friends the next year. Thinking back, that was the first time I really noticed Tinnitus. At that show, I remember we were standing right directly in front of the speakers the whole time. When we walked out from that show my ears were ringing so loudly and the ringing didn't stop until about 4-5 days after.
Aside from attending rock concerts throughout the later years of my life, I also joined another band that started my Sophmore year of high school and ended the summer before I became a Freshman in college. This band really took up a good majority of time those years. I'd have to say that we must of practiced together over hundreds of times and played close to a hundred shows as a band. Throughout that time I didn't protect my hearing until about half way through. I actually don't remember the reason why I started protecting my ears when practicing and playing shows but I ended up purchasing some hi-quality earplugs to use. All through this time of practicing and playing shows I never noticed any Tinnitus or hearing loss but I'm absolutely sure it was provoking the start of what I have now.
Also aside from attending rock concerts and playing in a band, I thoroughly enjoyed listening to music as talked about previously. I really started listening to music a lot, besides starting up a band, when I was a Sophmore in high school. I would listen to music while doing homework, I would listen to music while doing household activities (mowing the lawn, vacuuming, folding towels), I would listen to music every time I was driving my car, and I would even just sit in my room all day listening to music. I would even listen to songs and drum along to them at home as practice and because I really enjoyed to do it. Listening to music was something I could do that made me feel like I was exploring the unknown and learning something new everyday. It really gave me the ability to feel good about the future and think about the possibilities in life. I could even say that I think I was addicted to listening to music. Never once during these times did I notice a drastic change in my hearing. I never blasted the music in my ears during this time but I did listen to music for long periods of time.
Fast forward to my Freshman year of college. I was not playing in the band I was before, only jamming a few times with my fellow bandmate at his house while wearing ear protection. I attended only a few rock concerts and I wore ear protection to these shows. I also invested in some very high-quality in ear headphones by Shure that are a lot safer to use than Apple headphones because you don't have to blast them in your ear to get a nice sound. I continued to listen to music a lot during this time through these headphones and never noticed any change in my hearing. Fast forward to my Sophmore year of college. This was when I became very involved with the Audio Production side of music. I was attending Western Michigan University at the time and was looking to major in audio engineering, was taking music classes, and had started recording my own music with the recording equipment I obtained the summer after my Freshman year of college. At school I lived in a big apartment (it was basically a house) that allowed me to have all my recording equipment and instruments set up in its basement so that I could record and jam with my roommates any time I wanted to. I protected my hearing anytime we jammed but still listened to a lot of music through headphones while either doing homework or walking to school.
The last two weeks before my Sophmore year of college ended were when I started to notice a change in my hearing. I own good quality studio monitors that I record with and also listen to music with so I don't alway have to have headphones in. During those two weeks I started to notice a change in what I thought was frequency while listening to songs through these monitors. I noticed a difference in the high end or high frequency sound of the songs where I couldn't pick it up as well as before. At this point I was not worrying about my hearing at all because I was still feeling fine and could still hear the music fine. Fast forward to last summer. I've come home for the summer, I'm still recording music, playing the drums at home, and listening to music through headphones. About halfway through summer I realized I was having difficulty hearing the music I was listening to through the in-ear headphones I had been using for years. I could still hear the music playing but something was off and I was not sure what it was at the time. During last summer I was actually very aware of hearing loss at the time and was doing what I could to protect my hearing to the best of my ability. I stopped wearing the Shure in-ear headphones and purchased a pair of high-quality Sony Extra Bass over-the-ear headphones (which I have now learned is much safer than in-ear headphones when listening to music). I had a scare during the summer where I thought I did lose a good bit of my hearing but it ended up just being a huge piece of earwax blocking my ear canal. I went to a local ENT who helped remove it and got an audiogram done by an Audiologist right next door to the ENT. The audiogram showed I had excellent hearing, much better than most people have.
The summer progressed and I continued recording music with the slight notice of the high end change that happened during the last two weeks of my Sophmore year of college. The biggest change was I developed a small amount of constant ringing in my ears that didn't bother me that much because I still was feeling fine with my hearing. Fast forward to my Junior year of college that started about 3 months ago. Everything was going great, I had really figured out what I had a passion for which was audio production and even video production and wanted to make a career out of it in the end. The first two weeks of the school year ended and everything was looking fine. I could still listen to music through my studio monitors which still had a good quality sound, I could still hear music quite well through my over-the-ear headphones, and I was feeling optimistic about my future with music and a career I was really excited to get into.
THE HEARING CHANGE
Here is where things changed and my hearing became much worse. I have always made sure to be a healthy person and exercise whenever I could. Whenever I would workout, I would listen to music. I had been working out at the school's rec center the two weeks before hand and had been using my over-the-ear headphones but I was getting tired of having such a big bulky thing on my head while trying to exercise. It was the middle of the third week of the school year, Sept. 16th, when I decided it'd be nice to go back to my in-ear Shure headphones because they don't get in the way of working out at all. So I did, and exercised for close to an hour. The quality of the music playing in the headphones was not that great and I didn't really think it was that much of a problem during that time. I was not completely blasting the music either, I had the music at 60% on my Iphone and the in-ears being used does not play the music as loud as cheaper in-ear phones do. The rest of the day went well and I had a good night sleep.
I woke up the next morning and noticed a change in my hearing. The ringing in my ears that was barely there before was now 10x worse, I had muffled hearing, and my hearing was extremely sensitive to loud noises. It was bad. At the time, I was asking myself what in the world could of caused this and there no way in heck that it was my headphones that caused this problem. Nothing sounded the same anymore. The cars going by my apartment didn't sound the same, the room I sat in didn't sound the same, and the T.V. didn't sound the same. I tried listening to music through my studio monitors but I could barely listen to it without the ringing getting worse in my ears and the sound becoming jumbled. I became very afraid at this point that I had completely ruined my hearing so I frantically searched online for ways to heal your hearing or ways to bring it back to normal. I couldn't find anything except hearing aids, cochlear implants, or supplements that made a difference with your hearing. I decided that the supplements were worth partaking in and I purchased Vitamin A, C, E, Folic Acid, Magnesium, Beta Carotene, and B-12. I was most interested in the B-12 supplement because of what I had read online on how it's great for keeping your nervous system healthy and great for your hearing. My hearing was still not the same the next few days. About close to a week after my hearing loss occurred I decided to try the B-12 supplement to see if it would do anything for my hearing. I took one pill of the B-12 during the middle of the day (it was 2500 mcg, so a good amount) before my Film class that I was taking. I have to say it made me feel good the few minutes after I took it. I walked into my Film class about a half hour later and sat down to watch the movie which was planned to be shown that day. The movie was a French animated movie from 2007 that had beautiful music correlated with it and this is when I noticed something different. The ringing had gone down in my ears, the muffling of my ears had basically gone down, and I could clearly hear and feel the music that was playing from the movie through the speakers in the room. It was like a miracle and I could not believe how good I was feeling from realizing what was happening. My hearing problem had basically vanished right there and I thought I had saved my hearing. I went back to my apartment later that day and things were sounding like they were before the incident with my headphones. I played my acoustic guitar which sounded great, I could clearly hear noises outside my apartments open window, and even the music sounded like before on my studio monitors, maybe even better than before!
The next day the ringing came back, the muffled hearing had subsided a good bit, and my hearing went back to the problem it was before. I took B-12 again that day and my hearing returned to near normal again. Music especially just sounded great again. Everything was okay until later that day when the smoke alarm went off in my apartment kitchen after cooking some food. The sensitivity of my ears were still not back to normal from the headphone incident and boy did that alarm hurt my hearing. Now mind you I was living in a very tiny apartment at this time with wooden floors and nothing to absorb the sound from the smoke alarms so this alarm was very loud. I didn't have the reaction to cover my ears but to try and reset the alarm as quick as I could. I had nothing protecting my ears when I did this and it took me about 45 seconds, maybe more, to finally get it to stop making noise. After this I noticed that my hearing was shot. My ears were ringing terribly and I had lost the feeling that I had before after taking the B-12 that day. At the time I was listening to some Spotify through a Bose bluetooth small speaker I have but when I went back to listening to the music, it didn't sound the same. Something was off again.
Weeks passed and my hearing still did not improve, in fact it got worse. The muffling of the hearing was gone but the sensitivity was worse, the ringing was worse, and I just could not hear as well as before. I had to stop listening to music, I couldn't recording music anymore. I just could not focus on the sounds I was hearing and I was not feeling the same as I was before any of this ever happened. Things went downhill from there and I started to do poorly in my classes at school and began to get into a depression. About a month went by and I just could not continue at school so I ended up going back home to get away from the stress and to figure things out for the life I was going to live with the problem I was having. I tried to continue taking B-12 and all the other supplements along with it but my hearing never went back to how it was those two days when I first took the B-12 supplement. My hearing didn't improve at all through out this time and I believe it has gotten worse even up to today, November 16th, 2015.
Now don't stop reading from here because this is actually where the CONNECTIONS start to happen and how my life story ENORMOUSLY RELATES to my HEARING LOSS!
On October 1st, before I had come home for good from school, I visited the local Audiologist again back at home I had gone to during the summer. I was able to see the Audiologist again after taking a train home from school for the weekend. I explained to the Audiologist what had happened with the headphone incident and how confused I was on how I could of possibly gotten this hearing loss. We went through some possibilities and came up with maybe I had lost hair cells in my ears from playing the headphones to loudly (which didn't make sense but could of possibly happened). After I took a hearing test just like during the summer and what happened? There was basically NO DIFFERENCE in this Audiogram from the last Audiogram I took. None at all. Maybe just the teeny-tiniest change but it was nothing. How could I feel such a huge change in my hearing from now back to my hearing in the summer when it was completely fine except some very slight ringing? That doesn't make any sense at all.
Moving on to a few weeks ago
It wasn't until about a few weeks ago when I really started to focus in on how my hearing was at the time, information I could find on hearing loss, and what could be done to fix this problem I have because in the end I wanted my hearing back as closely as possible to the way it was before.
I did all I could to find out about how the ear works and the damages that can be done to it. All this time I truly believed I had damaged a bunch of hair cells in my ears and was never going to get them back. I did research on treatments being done to regenerate hair cells or repair damaged hair cells. I looked everywhere to find answers. I looked into Gene Therapy, I looked into Stem Cell Treatments, I looked into any kind of drug being developed to regrow hair cells. I would spend every moment of every day these past few weeks trying to find new information on regrowing hair cells because I was becoming so nervous that I had damaged my hair cells for good and would never be able to get them back to how they were before. It wasn't until I came across this article -( http://www.nydailynews.com/news/nat...den-hearing-loss-risk-study-article-1.2230945 )- that really changed my outlook on my "hearing loss" and the symptoms I was having from it. In the article, researchers of Harvard Medical School Eaton Peabody Laboratory claim that you can lose up to 90% of the nerve fibers in your ears without losing the ability to detect a tone in quiet. But once background noise is introduced, hearing ability drops dramatically. So, Hair Cells may be completely intact but hearing still lost if the nerve synapses are damaged. This got me to thinking. So there are nerves that connect from your ears to the brain that are not hair cells? That was a bit of relief for me giving me hope that maybe I didn't destroy my hair cells from the incident I had with my headphones. From this article I started my quest on finding some answers on "nerve fibers" in the ears.
I actually had a tough time finding more information about nerve damage in the ear and if I did find information it was usually an article needed to be purchased or a code needed to view the whole thing. But another concept had popped in my head that I wanted to figure out. If someone like myself has a "Normal Audiogram" and I have ringing in my ears, then what could be the problem? Tinnitus and a Normal Audiogram is what I looked into. I found three good articles on this idea that gave a great explanation to what could be wrong. In this first article -(http://www.tinnitus.org.uk/tinnitus-and-hidden-hearing-loss)- we are told that there are people who have normal audiograms but who still have ringing in the ears. The focus lies on what's called the "Hearing Thershold". We have always thought that if your Audiogram Test is normal then your Hearing Threshold must be normal. If you read the article it talks about tests being done on humans and the use of a testing system called "ABR" or Auditory Brain Response. This test determines the electrical activity generated by the first processing stages of the auditory system. I'm not going to explain all the other info on what's tested because you need to read through the article. I will say that through a testing done on mice after exposure of night club sound levels (2 hours at 100 dB SPL) there was a temporary shift of the hearing threshold that recovered to normal levels within days, but there was a permanent reduction of the amplitude of wave I....and it goes on talking about how its similar to a test done before on the group of humans. But the article goes on to say that the after close inspection of the inner ears of the mice, there was a large fraction of their auditory nerve fibers that had lost contact to the hair cells in the cochlea. They continue to say that this is like unplugging half the cables between an array of microphones and the sound recorder. The mice had retained just enough auditory nerve fibres to still be able to hear soft sounds, but the loss of contact between many auditory nerve fibres and the hair cells meant that for loud sounds, much fewer fibres were responding, thus reducing the total output of the auditory nerve. BIG NEWS RIGHT HERE.
(Here is the article continued):
How such 'hidden hearing loss' can lead to tinnitus can be directly understood with the help of our computer model. As a large fraction of the auditory nerve fibres no longer respond to sound, the overall signal from the auditory nerve is decreased, and therefore the nerve cells in the auditory brain receive less input and become less active overall. When these nerve cells then try to get their mean activity back up to the healthy target level, they increase their response gain and respond more vigorously to incoming signals.
This increased gain could also be seen in our human ABR data, as the amplitude of wave V was normal in the tinnitus group even though wave I (the input signal) was smaller than normal. However, a side-effect of the gain increase is an amplification of neuronal noise, which gives rise to increased spontaneous activity of the nerve cells – the model develops tinnitus.
BOOM.
This gives me the notion that a good majority of you that have tinnitus had to of damaged the nerve fibers in your inner ears and not the hair cells in your ears. If you have a near normal audiogram or even a little below it and seem to have hearing loss and loud ringing in your ears then this will apply directly to you but if not then your hair cells must have been damaged in whatever noise-induced incident happened to you.
Research is continued:
This was where I continued to find more connections to the past symptoms I was having. Here is an article -(http://www.hear-it.org/loud-music-damages-nerves-brain)- Loud music you play through your headphones, which is just loud noise (noise levels above 110 decibels), damages the nerves connected to the brain just like Multiple Sclerosis. The sound waves enter the ear and eventually reach the nerves connected to the hair cells in the inner ear and strip these nerve fibers of their insulation that covers them called the "myelin sheath". Now it talks about in the article that over time the myelin sheath grows back but when you think about it, if you have continuously listened to loud music, attended loud concerts, have had a job where you're bombarded by loud noise, then how is the myelin sheath supposed to grow back? From this online source and other online sources I've read, scientists say the myelin sheath or nerves grow back 1mm a day meaning hearing can recover. Now think back to the article you just read above this. Hearing does recover but the Hearing Threshold does not and the nerves are still disconnected or have died from the loud noise over time unless it regrows back fast enough before you do any more damage.
Connection to my hearing loss two months ago:
Remember me talking about when I took the B-12 2500 mcg supplement two days in a row about a week after my headphone incident? If you need me to refresh your memory, B-12 is great for the nervous system and any disorders you have with it. Better yet, B-12 actually helps regrow the Myelin Sheath on nerves to keep a strong connection going! Now remember I said that after taking the B-12 both days, it felt like I got my hearing almost fully back? Well I must of been able to repair the lost nerve connections that happened with my hearing loss through the B-12 by building the myelin sheath back up. But when the smoke alarm went off in my apartment after the 2nd straight day of taking the B-12, my nerves must of been damaged even more from the loud noise of the alarm and from there they must of lost even further connection or the neuron died right then and there.
From that day to now (Novemember 16th, 2015) I still have not been able to re-establish a strong connection of my nerves to my inner ear hair cells because I have yet to feel and hear like I could when I took the B-12 those two days in a row after the incident.
The connections continue:
After figure everything out above, I dove more deeply into the shifting of Hearing Thresholds for people with hearing loss. The first article I brought up above all this talking about the "Earbud Increases Hidden Hearing Loss", states that when people who have a hidden hearing loss are introduced to background noise, their hearing capabilities dramatically drop. I tested this out for myself and paid very close attention to how I could hear things when noises very involved in the background. I first noticed a huge difference in my hearing abilities with background noise when I went out to eat at a restaurant for my Uncle's Birthday dinner. I had an extremely hard time focusing in on conversations going on because of not only noises happening all around the restaurant but even the conversations going on at the dinner table. I struggled to hear someone speaking to me that was an arms length away from me. I could hear and keep a conversation up but the struggle I now had with all this was never ever there before this incident. This got me to thinking. What is really considered background noise? Is it just noise that our brains to focus in on while performing other tasks or is it just considered noise that is louder than any other noise in the room?
Connection between Background Noise & Music:
I first starting making a connection between background noise and music when I was trying to listen to the radio in the car while out driving at home not to long ago. A song came on "Say it Ain't So by Weezer," that I had heard millions of times before in the past through headphones and speakers. There was something completely different with the song though. The low bass guitar was completely overwhelming my hearing and flooding out the rest of the song. I could still hear the vocals but it seemed like the electric guitars in the song were barely there. Why was this happening? Well here is how I put it. You can look at music almost like background noise in a restaurant. Certain frequencies in songs are louder than others. If you did not know, low frequencies give off the loudest noise and can travel for farther distances than mid or high frequencies. Think of when people play hip hop music in their cars or inside somewhere. What do you most notably hear if they have a good speaker system? The BASS or LOW END!! This is what our ears can most certainly pick up and it relates to background noises because a background noise can be a loud noise that is louder or more distinguishable than other noises around it. So why is the bass guitar now sticking out so much for me when I listen to songs through a stereo system? I believe the brain focuses on whatever sound is the loudest heard. When you listen to a song, all the different instruments playing can be thought of as background noise and talking to someone at a restaurant. If you are trying to focus on let's say the drums playing then any of the other instruments playing in the song will be like background noise. Your brain is focusing on the drums and automatically tuning out all the other instruments playing.
There is where Nerve Fibers come into play again
I found another article about the inner ear that included a section focused on hidden hearing loss and what it's all about. The article -(http://hyperacusisfocus.org/innerear/)- if you scroll down to the section titled "Hidden Hearing Loss" the second paragraph states that each Inner Hair Cell is connected to roughly 10 nerve fibers that react to different loudness levels. It also talks about (like explained before) that losing these nerve fibers will not show up on a hearing test as long as lower loudness fibers remained intact. The article continues to talk about the different thresholds related to nerve fibers and how higher loudness level nerves are more susceptible to damage than the lower loudness level nerves. Relating to music and how the lower end really sticks out to me now. The article also explains how these nerve fibers relate to hyperacusis and how the brain turns up the gain so that it can reach normal hearing levels again.
There is one more article I'd like to link you to that shows laboratory work done on the cochlea. The 2nd to last paragraph of this article states that after several-post exposures have been done to an animal being studied and their inner ear was looked at through a microscopic structure, there was a 50% loss of synaptic connections between hair cells and neurons within 1 day after exposure. This connects to when I used the B-12 close to a week after the incident. The supplement must of somehow reconnected the lost synapses to whatever hair cells it got disconnected from.
Summary
- Tinnitus sufferers with normal hearing have lost a majority of their nerve fibers connected to the hair cells in their ears
- Those who have lost a good amount of their nerve fibers have difficulty hearing with background noise
- Noise-induced hearing loss incidents involves a good amount of their nerve fibers disconnecting and not always the loss of hair cells
- Headphones damage the nerves like Multiple Sclerosis
- Headphones can make you lose up to 90% of your nerve fibers
- B-12 could possibly help your nerve fibers if disconnected from noise-induced trauma
Present day:
i hope you guys were able to follow along with everything I put together in this post. I apologize again for how long it was but I really had to type all this out to explain everything that has happened to me and how these connections can help you guys out too.
As of right now I'm set to see an Audiologist and ENT at The University of Michigan where I will explain to them the interesting sources I've found and how it all connects to the hearing loss I have. I have not had anymore signs of recovery in my hearing and I believe it has actually gotten worse since two months ago. I hope to be able to take an ABR test at U of M and even a test called a DPOAE, but I'm not sure if they have those tests so I plan to call soon to make sure they do. If not then I'll search for other routes.
I've attachd a jpg. of an example of nerve fibers damaged from noise. Here is the websites url too -(http://www.hearingreview.com/2014/0...anism-nerve-fiber-loss-discussed-asa-meeting/)-
If you guys have any questions feel free to message me on this site or comment down below.

First off I'd like to say it's great to see such a huge community working together to figure out what can be done to not only stop hearing loss but restore it.

Now many of the things I'm about to talk about in this post are all based off how I've felt these past months, connections I've made through articles I've found online, and some deep thinking about how my hearing has been every day since the incident.
My Life leading Up to My Hearing Problem
Before I get into to how I got this hearing loss/tinnitus and the symptoms I have, I'd like to talk about what I've been involved with ever since I was a wee-little boy. Music has always been a passion for me. I remember buying my first cd ever in 2nd grade, it was Linkin Park's Reanimation Remix album. I had no idea who they were but I thought the artwork was very cool so I purchased it. That's the first time I can recall from my memory that I fell in love with listening to music. Fast forward to when I'm an 8th grader. I started a band playing the drums with two other friends where we only played one show but it was something that opened up a new horizon for me. I attended my first ever rock concert, it was a Wolfmother show, with a few friends the next year. Thinking back, that was the first time I really noticed Tinnitus. At that show, I remember we were standing right directly in front of the speakers the whole time. When we walked out from that show my ears were ringing so loudly and the ringing didn't stop until about 4-5 days after.
Aside from attending rock concerts throughout the later years of my life, I also joined another band that started my Sophmore year of high school and ended the summer before I became a Freshman in college. This band really took up a good majority of time those years. I'd have to say that we must of practiced together over hundreds of times and played close to a hundred shows as a band. Throughout that time I didn't protect my hearing until about half way through. I actually don't remember the reason why I started protecting my ears when practicing and playing shows but I ended up purchasing some hi-quality earplugs to use. All through this time of practicing and playing shows I never noticed any Tinnitus or hearing loss but I'm absolutely sure it was provoking the start of what I have now.
Also aside from attending rock concerts and playing in a band, I thoroughly enjoyed listening to music as talked about previously. I really started listening to music a lot, besides starting up a band, when I was a Sophmore in high school. I would listen to music while doing homework, I would listen to music while doing household activities (mowing the lawn, vacuuming, folding towels), I would listen to music every time I was driving my car, and I would even just sit in my room all day listening to music. I would even listen to songs and drum along to them at home as practice and because I really enjoyed to do it. Listening to music was something I could do that made me feel like I was exploring the unknown and learning something new everyday. It really gave me the ability to feel good about the future and think about the possibilities in life. I could even say that I think I was addicted to listening to music. Never once during these times did I notice a drastic change in my hearing. I never blasted the music in my ears during this time but I did listen to music for long periods of time.
Fast forward to my Freshman year of college. I was not playing in the band I was before, only jamming a few times with my fellow bandmate at his house while wearing ear protection. I attended only a few rock concerts and I wore ear protection to these shows. I also invested in some very high-quality in ear headphones by Shure that are a lot safer to use than Apple headphones because you don't have to blast them in your ear to get a nice sound. I continued to listen to music a lot during this time through these headphones and never noticed any change in my hearing. Fast forward to my Sophmore year of college. This was when I became very involved with the Audio Production side of music. I was attending Western Michigan University at the time and was looking to major in audio engineering, was taking music classes, and had started recording my own music with the recording equipment I obtained the summer after my Freshman year of college. At school I lived in a big apartment (it was basically a house) that allowed me to have all my recording equipment and instruments set up in its basement so that I could record and jam with my roommates any time I wanted to. I protected my hearing anytime we jammed but still listened to a lot of music through headphones while either doing homework or walking to school.
The last two weeks before my Sophmore year of college ended were when I started to notice a change in my hearing. I own good quality studio monitors that I record with and also listen to music with so I don't alway have to have headphones in. During those two weeks I started to notice a change in what I thought was frequency while listening to songs through these monitors. I noticed a difference in the high end or high frequency sound of the songs where I couldn't pick it up as well as before. At this point I was not worrying about my hearing at all because I was still feeling fine and could still hear the music fine. Fast forward to last summer. I've come home for the summer, I'm still recording music, playing the drums at home, and listening to music through headphones. About halfway through summer I realized I was having difficulty hearing the music I was listening to through the in-ear headphones I had been using for years. I could still hear the music playing but something was off and I was not sure what it was at the time. During last summer I was actually very aware of hearing loss at the time and was doing what I could to protect my hearing to the best of my ability. I stopped wearing the Shure in-ear headphones and purchased a pair of high-quality Sony Extra Bass over-the-ear headphones (which I have now learned is much safer than in-ear headphones when listening to music). I had a scare during the summer where I thought I did lose a good bit of my hearing but it ended up just being a huge piece of earwax blocking my ear canal. I went to a local ENT who helped remove it and got an audiogram done by an Audiologist right next door to the ENT. The audiogram showed I had excellent hearing, much better than most people have.
The summer progressed and I continued recording music with the slight notice of the high end change that happened during the last two weeks of my Sophmore year of college. The biggest change was I developed a small amount of constant ringing in my ears that didn't bother me that much because I still was feeling fine with my hearing. Fast forward to my Junior year of college that started about 3 months ago. Everything was going great, I had really figured out what I had a passion for which was audio production and even video production and wanted to make a career out of it in the end. The first two weeks of the school year ended and everything was looking fine. I could still listen to music through my studio monitors which still had a good quality sound, I could still hear music quite well through my over-the-ear headphones, and I was feeling optimistic about my future with music and a career I was really excited to get into.
THE HEARING CHANGE
Here is where things changed and my hearing became much worse. I have always made sure to be a healthy person and exercise whenever I could. Whenever I would workout, I would listen to music. I had been working out at the school's rec center the two weeks before hand and had been using my over-the-ear headphones but I was getting tired of having such a big bulky thing on my head while trying to exercise. It was the middle of the third week of the school year, Sept. 16th, when I decided it'd be nice to go back to my in-ear Shure headphones because they don't get in the way of working out at all. So I did, and exercised for close to an hour. The quality of the music playing in the headphones was not that great and I didn't really think it was that much of a problem during that time. I was not completely blasting the music either, I had the music at 60% on my Iphone and the in-ears being used does not play the music as loud as cheaper in-ear phones do. The rest of the day went well and I had a good night sleep.
I woke up the next morning and noticed a change in my hearing. The ringing in my ears that was barely there before was now 10x worse, I had muffled hearing, and my hearing was extremely sensitive to loud noises. It was bad. At the time, I was asking myself what in the world could of caused this and there no way in heck that it was my headphones that caused this problem. Nothing sounded the same anymore. The cars going by my apartment didn't sound the same, the room I sat in didn't sound the same, and the T.V. didn't sound the same. I tried listening to music through my studio monitors but I could barely listen to it without the ringing getting worse in my ears and the sound becoming jumbled. I became very afraid at this point that I had completely ruined my hearing so I frantically searched online for ways to heal your hearing or ways to bring it back to normal. I couldn't find anything except hearing aids, cochlear implants, or supplements that made a difference with your hearing. I decided that the supplements were worth partaking in and I purchased Vitamin A, C, E, Folic Acid, Magnesium, Beta Carotene, and B-12. I was most interested in the B-12 supplement because of what I had read online on how it's great for keeping your nervous system healthy and great for your hearing. My hearing was still not the same the next few days. About close to a week after my hearing loss occurred I decided to try the B-12 supplement to see if it would do anything for my hearing. I took one pill of the B-12 during the middle of the day (it was 2500 mcg, so a good amount) before my Film class that I was taking. I have to say it made me feel good the few minutes after I took it. I walked into my Film class about a half hour later and sat down to watch the movie which was planned to be shown that day. The movie was a French animated movie from 2007 that had beautiful music correlated with it and this is when I noticed something different. The ringing had gone down in my ears, the muffling of my ears had basically gone down, and I could clearly hear and feel the music that was playing from the movie through the speakers in the room. It was like a miracle and I could not believe how good I was feeling from realizing what was happening. My hearing problem had basically vanished right there and I thought I had saved my hearing. I went back to my apartment later that day and things were sounding like they were before the incident with my headphones. I played my acoustic guitar which sounded great, I could clearly hear noises outside my apartments open window, and even the music sounded like before on my studio monitors, maybe even better than before!
The next day the ringing came back, the muffled hearing had subsided a good bit, and my hearing went back to the problem it was before. I took B-12 again that day and my hearing returned to near normal again. Music especially just sounded great again. Everything was okay until later that day when the smoke alarm went off in my apartment kitchen after cooking some food. The sensitivity of my ears were still not back to normal from the headphone incident and boy did that alarm hurt my hearing. Now mind you I was living in a very tiny apartment at this time with wooden floors and nothing to absorb the sound from the smoke alarms so this alarm was very loud. I didn't have the reaction to cover my ears but to try and reset the alarm as quick as I could. I had nothing protecting my ears when I did this and it took me about 45 seconds, maybe more, to finally get it to stop making noise. After this I noticed that my hearing was shot. My ears were ringing terribly and I had lost the feeling that I had before after taking the B-12 that day. At the time I was listening to some Spotify through a Bose bluetooth small speaker I have but when I went back to listening to the music, it didn't sound the same. Something was off again.
Weeks passed and my hearing still did not improve, in fact it got worse. The muffling of the hearing was gone but the sensitivity was worse, the ringing was worse, and I just could not hear as well as before. I had to stop listening to music, I couldn't recording music anymore. I just could not focus on the sounds I was hearing and I was not feeling the same as I was before any of this ever happened. Things went downhill from there and I started to do poorly in my classes at school and began to get into a depression. About a month went by and I just could not continue at school so I ended up going back home to get away from the stress and to figure things out for the life I was going to live with the problem I was having. I tried to continue taking B-12 and all the other supplements along with it but my hearing never went back to how it was those two days when I first took the B-12 supplement. My hearing didn't improve at all through out this time and I believe it has gotten worse even up to today, November 16th, 2015.
Now don't stop reading from here because this is actually where the CONNECTIONS start to happen and how my life story ENORMOUSLY RELATES to my HEARING LOSS!
On October 1st, before I had come home for good from school, I visited the local Audiologist again back at home I had gone to during the summer. I was able to see the Audiologist again after taking a train home from school for the weekend. I explained to the Audiologist what had happened with the headphone incident and how confused I was on how I could of possibly gotten this hearing loss. We went through some possibilities and came up with maybe I had lost hair cells in my ears from playing the headphones to loudly (which didn't make sense but could of possibly happened). After I took a hearing test just like during the summer and what happened? There was basically NO DIFFERENCE in this Audiogram from the last Audiogram I took. None at all. Maybe just the teeny-tiniest change but it was nothing. How could I feel such a huge change in my hearing from now back to my hearing in the summer when it was completely fine except some very slight ringing? That doesn't make any sense at all.
Moving on to a few weeks ago
It wasn't until about a few weeks ago when I really started to focus in on how my hearing was at the time, information I could find on hearing loss, and what could be done to fix this problem I have because in the end I wanted my hearing back as closely as possible to the way it was before.
I did all I could to find out about how the ear works and the damages that can be done to it. All this time I truly believed I had damaged a bunch of hair cells in my ears and was never going to get them back. I did research on treatments being done to regenerate hair cells or repair damaged hair cells. I looked everywhere to find answers. I looked into Gene Therapy, I looked into Stem Cell Treatments, I looked into any kind of drug being developed to regrow hair cells. I would spend every moment of every day these past few weeks trying to find new information on regrowing hair cells because I was becoming so nervous that I had damaged my hair cells for good and would never be able to get them back to how they were before. It wasn't until I came across this article -( http://www.nydailynews.com/news/nat...den-hearing-loss-risk-study-article-1.2230945 )- that really changed my outlook on my "hearing loss" and the symptoms I was having from it. In the article, researchers of Harvard Medical School Eaton Peabody Laboratory claim that you can lose up to 90% of the nerve fibers in your ears without losing the ability to detect a tone in quiet. But once background noise is introduced, hearing ability drops dramatically. So, Hair Cells may be completely intact but hearing still lost if the nerve synapses are damaged. This got me to thinking. So there are nerves that connect from your ears to the brain that are not hair cells? That was a bit of relief for me giving me hope that maybe I didn't destroy my hair cells from the incident I had with my headphones. From this article I started my quest on finding some answers on "nerve fibers" in the ears.
I actually had a tough time finding more information about nerve damage in the ear and if I did find information it was usually an article needed to be purchased or a code needed to view the whole thing. But another concept had popped in my head that I wanted to figure out. If someone like myself has a "Normal Audiogram" and I have ringing in my ears, then what could be the problem? Tinnitus and a Normal Audiogram is what I looked into. I found three good articles on this idea that gave a great explanation to what could be wrong. In this first article -(http://www.tinnitus.org.uk/tinnitus-and-hidden-hearing-loss)- we are told that there are people who have normal audiograms but who still have ringing in the ears. The focus lies on what's called the "Hearing Thershold". We have always thought that if your Audiogram Test is normal then your Hearing Threshold must be normal. If you read the article it talks about tests being done on humans and the use of a testing system called "ABR" or Auditory Brain Response. This test determines the electrical activity generated by the first processing stages of the auditory system. I'm not going to explain all the other info on what's tested because you need to read through the article. I will say that through a testing done on mice after exposure of night club sound levels (2 hours at 100 dB SPL) there was a temporary shift of the hearing threshold that recovered to normal levels within days, but there was a permanent reduction of the amplitude of wave I....and it goes on talking about how its similar to a test done before on the group of humans. But the article goes on to say that the after close inspection of the inner ears of the mice, there was a large fraction of their auditory nerve fibers that had lost contact to the hair cells in the cochlea. They continue to say that this is like unplugging half the cables between an array of microphones and the sound recorder. The mice had retained just enough auditory nerve fibres to still be able to hear soft sounds, but the loss of contact between many auditory nerve fibres and the hair cells meant that for loud sounds, much fewer fibres were responding, thus reducing the total output of the auditory nerve. BIG NEWS RIGHT HERE.
(Here is the article continued):
How such 'hidden hearing loss' can lead to tinnitus can be directly understood with the help of our computer model. As a large fraction of the auditory nerve fibres no longer respond to sound, the overall signal from the auditory nerve is decreased, and therefore the nerve cells in the auditory brain receive less input and become less active overall. When these nerve cells then try to get their mean activity back up to the healthy target level, they increase their response gain and respond more vigorously to incoming signals.
This increased gain could also be seen in our human ABR data, as the amplitude of wave V was normal in the tinnitus group even though wave I (the input signal) was smaller than normal. However, a side-effect of the gain increase is an amplification of neuronal noise, which gives rise to increased spontaneous activity of the nerve cells – the model develops tinnitus.
BOOM.
This gives me the notion that a good majority of you that have tinnitus had to of damaged the nerve fibers in your inner ears and not the hair cells in your ears. If you have a near normal audiogram or even a little below it and seem to have hearing loss and loud ringing in your ears then this will apply directly to you but if not then your hair cells must have been damaged in whatever noise-induced incident happened to you.
Research is continued:
This was where I continued to find more connections to the past symptoms I was having. Here is an article -(http://www.hear-it.org/loud-music-damages-nerves-brain)- Loud music you play through your headphones, which is just loud noise (noise levels above 110 decibels), damages the nerves connected to the brain just like Multiple Sclerosis. The sound waves enter the ear and eventually reach the nerves connected to the hair cells in the inner ear and strip these nerve fibers of their insulation that covers them called the "myelin sheath". Now it talks about in the article that over time the myelin sheath grows back but when you think about it, if you have continuously listened to loud music, attended loud concerts, have had a job where you're bombarded by loud noise, then how is the myelin sheath supposed to grow back? From this online source and other online sources I've read, scientists say the myelin sheath or nerves grow back 1mm a day meaning hearing can recover. Now think back to the article you just read above this. Hearing does recover but the Hearing Threshold does not and the nerves are still disconnected or have died from the loud noise over time unless it regrows back fast enough before you do any more damage.
Connection to my hearing loss two months ago:
Remember me talking about when I took the B-12 2500 mcg supplement two days in a row about a week after my headphone incident? If you need me to refresh your memory, B-12 is great for the nervous system and any disorders you have with it. Better yet, B-12 actually helps regrow the Myelin Sheath on nerves to keep a strong connection going! Now remember I said that after taking the B-12 both days, it felt like I got my hearing almost fully back? Well I must of been able to repair the lost nerve connections that happened with my hearing loss through the B-12 by building the myelin sheath back up. But when the smoke alarm went off in my apartment after the 2nd straight day of taking the B-12, my nerves must of been damaged even more from the loud noise of the alarm and from there they must of lost even further connection or the neuron died right then and there.
From that day to now (Novemember 16th, 2015) I still have not been able to re-establish a strong connection of my nerves to my inner ear hair cells because I have yet to feel and hear like I could when I took the B-12 those two days in a row after the incident.
The connections continue:
After figure everything out above, I dove more deeply into the shifting of Hearing Thresholds for people with hearing loss. The first article I brought up above all this talking about the "Earbud Increases Hidden Hearing Loss", states that when people who have a hidden hearing loss are introduced to background noise, their hearing capabilities dramatically drop. I tested this out for myself and paid very close attention to how I could hear things when noises very involved in the background. I first noticed a huge difference in my hearing abilities with background noise when I went out to eat at a restaurant for my Uncle's Birthday dinner. I had an extremely hard time focusing in on conversations going on because of not only noises happening all around the restaurant but even the conversations going on at the dinner table. I struggled to hear someone speaking to me that was an arms length away from me. I could hear and keep a conversation up but the struggle I now had with all this was never ever there before this incident. This got me to thinking. What is really considered background noise? Is it just noise that our brains to focus in on while performing other tasks or is it just considered noise that is louder than any other noise in the room?
Connection between Background Noise & Music:
I first starting making a connection between background noise and music when I was trying to listen to the radio in the car while out driving at home not to long ago. A song came on "Say it Ain't So by Weezer," that I had heard millions of times before in the past through headphones and speakers. There was something completely different with the song though. The low bass guitar was completely overwhelming my hearing and flooding out the rest of the song. I could still hear the vocals but it seemed like the electric guitars in the song were barely there. Why was this happening? Well here is how I put it. You can look at music almost like background noise in a restaurant. Certain frequencies in songs are louder than others. If you did not know, low frequencies give off the loudest noise and can travel for farther distances than mid or high frequencies. Think of when people play hip hop music in their cars or inside somewhere. What do you most notably hear if they have a good speaker system? The BASS or LOW END!! This is what our ears can most certainly pick up and it relates to background noises because a background noise can be a loud noise that is louder or more distinguishable than other noises around it. So why is the bass guitar now sticking out so much for me when I listen to songs through a stereo system? I believe the brain focuses on whatever sound is the loudest heard. When you listen to a song, all the different instruments playing can be thought of as background noise and talking to someone at a restaurant. If you are trying to focus on let's say the drums playing then any of the other instruments playing in the song will be like background noise. Your brain is focusing on the drums and automatically tuning out all the other instruments playing.
There is where Nerve Fibers come into play again
I found another article about the inner ear that included a section focused on hidden hearing loss and what it's all about. The article -(http://hyperacusisfocus.org/innerear/)- if you scroll down to the section titled "Hidden Hearing Loss" the second paragraph states that each Inner Hair Cell is connected to roughly 10 nerve fibers that react to different loudness levels. It also talks about (like explained before) that losing these nerve fibers will not show up on a hearing test as long as lower loudness fibers remained intact. The article continues to talk about the different thresholds related to nerve fibers and how higher loudness level nerves are more susceptible to damage than the lower loudness level nerves. Relating to music and how the lower end really sticks out to me now. The article also explains how these nerve fibers relate to hyperacusis and how the brain turns up the gain so that it can reach normal hearing levels again.
There is one more article I'd like to link you to that shows laboratory work done on the cochlea. The 2nd to last paragraph of this article states that after several-post exposures have been done to an animal being studied and their inner ear was looked at through a microscopic structure, there was a 50% loss of synaptic connections between hair cells and neurons within 1 day after exposure. This connects to when I used the B-12 close to a week after the incident. The supplement must of somehow reconnected the lost synapses to whatever hair cells it got disconnected from.
Summary
- Tinnitus sufferers with normal hearing have lost a majority of their nerve fibers connected to the hair cells in their ears
- Those who have lost a good amount of their nerve fibers have difficulty hearing with background noise
- Noise-induced hearing loss incidents involves a good amount of their nerve fibers disconnecting and not always the loss of hair cells
- Headphones damage the nerves like Multiple Sclerosis
- Headphones can make you lose up to 90% of your nerve fibers
- B-12 could possibly help your nerve fibers if disconnected from noise-induced trauma
Present day:
i hope you guys were able to follow along with everything I put together in this post. I apologize again for how long it was but I really had to type all this out to explain everything that has happened to me and how these connections can help you guys out too.
As of right now I'm set to see an Audiologist and ENT at The University of Michigan where I will explain to them the interesting sources I've found and how it all connects to the hearing loss I have. I have not had anymore signs of recovery in my hearing and I believe it has actually gotten worse since two months ago. I hope to be able to take an ABR test at U of M and even a test called a DPOAE, but I'm not sure if they have those tests so I plan to call soon to make sure they do. If not then I'll search for other routes.
I've attachd a jpg. of an example of nerve fibers damaged from noise. Here is the websites url too -(http://www.hearingreview.com/2014/0...anism-nerve-fiber-loss-discussed-asa-meeting/)-
