Hi everyone!
First off I have to say that I understand what all of you are going through as I have been blessed with T after a bomb blast for the last months myself.
I'm not sure how helpful this post is going to be, but I've decided to write down all of my thoughts and experiences with T from the past years in hope that it can be useful to someone that is trying to get to the bottom of this condition.
I'm also trying to resonate towards what this T really is and where it originates. At least the kind of T that I have and probably a lot of other people as well.
First off, I have had short lived T lots of times after noise exposure at work etc.
Almost all my life I have had a 10db dip at 6khz according to the audiogram tests, which has given me a faint constant T at 6khz that has never really bothered me.
But this time, it's something different.
Every time I have experienced short lived T from noise exposure, the threshold shift kicks in, and from what I understand,
this is a protective mechanism within the ear to protect the cochlea from damage by lowering the perceived sound volume and it works by the help of the tensor tympani muscle contracting the tympanic membrane (eardrum) lowering the sound vibrations (volume) transferred to the cochlea. Then soon after the threshold returns to normal, I have this buzzing sound at about 15khz (much similar sound like those old 70mod televisions when it doesnt receive any analog broadcasting signal) lasting for a few minutes to a few hours.
After that, a pretty high volume <beeeep> lasting for about 2 - 4 seconds kicks in, starting in the 3khz range and working it's way up to the 16khz+ range until it fades out, as it's no longer in the frequency range that my ear can perceive. The buzz resolves when this happens. And it has happened a lot of times.
What exactly happens in that moment is for me a little unclear, but I have felt movements in my ear when it has happened, so I always thought that it's the tensor tympani muscle
that is resetting it's threshold back to where it was before the exposure (fine tuning the eardrum from being in an alerted state).
From wikipedia:
"Following exposure to intolerable sounds, this contraction of the tensor tympani muscle tightens the ear drum, which can lead to the symptoms of ear pain/a fluttering sensation/a sensation of fullness in the ear (in the absence of any middle or inner ear pathology)."
I am indeed experiencing a fullness within my ears, mild hyperacusis and some kind of ear pain from time to time like so many other also complain about.
I can even feel some kind of muscle movement inside my ear from time to time, and that is when my T changes volume and frequency as well.
My eardrum is not perforated according to an ENT and there is nothing measurable damage to be seen, and the sensation of fullness is still present.
And for the record, MRI and CT was fine.
Moving my neck or clenching my teeth alter my T's volume and pitch for a few seconds for then to settle back to where it was even if I keep the neck or jaw position that previously altered it.
I'm trying to understand the mechanics behind this type of T, and I strongly believe that it might originate from som mechanical part inside the ear, maybe the tensor tympani muscle.
I do not believe it is caused by hearing loss, as I already have a small dip at 6khz, and have had a faint T regaring this loss almost all my life (an accident from when I was a child when I hit solid metal with a large hammer). but the T I have now is more like a "ringing" sensation and it is constantly changing, even moving from ear to ear, it stops for a few milliseconds for then to return.
And together with the fullness and the sensetion of muscle movements inside the ear, and an unchanged audiogram I cannot see how this is related to hearing loss or damaged hair cells or nerves within the cochlea, but of course it might be both as the audiograms should be more detailed.
I also have to say that my 6khz T that is related to loss, does not change pitch while moving my neck, jaw etc. It is constant and it has always been. It has never given me any sensation of fullness or pain as well.
So here are my thoughts.
T related to hearing loss has a constant pitch and it isn't alterable by moving muscles.
My friends mother has got T related to sewere hearing loss, and she has indeed a constant sound that isn't alterable.
And what is funny is how little it takes to get this type of T i now have to spike.
So, what does that mean? That a relatively low and safe sound are now damaging our hearing?
I wouldn't think so. I find it more reasonable that this is a protective mechanism that has gone out of wack or that some part of the cilia or the connecting nerves has entered a different state and become overactive just to protect us from doing it again.
I can still hear sounds that has the same pitch as my T as long as the volume is higher than the T, and I can hear it equally good in both ears.
And what I find really confusing, is that I can even alter the sound of my new T by just using my mind (by visualizing it higher or lower in pitch).
Any thoughts or personal experiences are welcome
---------------------------------------------------------------------------------------------------------
Are there any research papers out there that measures structural changes within the ear to the microscopic scale before and after loud noise exposure?
Or that measures structural changes in that gap before the threshold shift kicks in and until the remaining T resolves on its own?
It would be really interesting to see what exactly is going on within that timeframe and what pathways is being activated in the brain until the T has resolved.
Both for those that develop short term T and those who develop chronic or permanent T.
I realize that this post got a bit longer than intended, but I really hope that it could be of use to someone out there.
At least this is my humble experience with two different beasts
God bless you all and a special thanks to those people that are developing and maintaining this forum!
