Why Do Some People Exposed to the Same Loud Noises Not Get Tinnitus While Others Do?

I'm just curious.

Genetics and evolution. The amount makes the poison.

For instance, if you start taking snake venom in very small quantities and step by step upper the dosage eventually your body will build resistance. And one day, your body is completely immune against a full snake bite.

Because world if full of injustice and overall a horrible place to live.

I blame it on drugs, toxins or past trauma to the head or to the ears. My ears could take a hell of a lot of noise prior to barotrauma and ototoxic drug damage. Now, I have delicate glass ears.

We all have differing internal physiologies. So some get it and others do not. Just like some may catch the cold going around work and some may not. Just like some are allergic to pollen and others can breathe it in all day without a sniffle. Just like brown eyes vs. green eyes. vs. blue eyes, except the tinnitus predisposition is inside, and not visible.

Would love know why I have Menieres and Bilateral tinnitus and sever asthma and vocal cord disfunction and I'm a twin and she's fine.
I'm the kind and caring one and she is not interested in anyting if there is nothing in it for her.

Life can suck at times but taking charge and doing what you love when you can and helping others....makes me happy....lots of love glynis

I think it has to do with what we call emotions. The neurotransmitters of our brain that allow us to feel good, process information, and store it all in neurons and brain cells that then allow us to retrieve that information over and over again until our brain loses them. I've learned recently that not everyone has emotions or that some people do have emotions but their neurons are wired much differently than others. It all depends on your dna, your cells, and your bodies overall ability to thrive and survive in this world. As you developed as a baby, and your brain started learning about the world. I'm still very interested in how the development of ones brain happens as they age from birth and I don't understand enough yet to state anything about it in this post. But I do understand that what we are born with and how it develops up until we are a young adult, is what we will be stimulated by for the rest of our adulthood. I've read that the ringing one hears when they've acoustically damaged their "hearing" and chronic pain are connected to some of the same regions in our brain.

I believe that some people logically experience this world and were born that way and then I believe there are many that emotionally experience this world. I'm not saying that those that were born with a logical brain don't experience emotions, but I'm speaking about the emotional information that's processed in those who were born with an emotional/creative side. Those who were born emotional, experience much of these emotions through their brain's ability to emotionally process sound. This happens through in-going auditory nerves between the brain's auditory region/limbic system and the hair cells of the cochlea. When these nerves are damaged and part of the brain's input to what allowed it to emotionally process outside information has been lost, then you're going to feel lower than what you would feel before. You aren't chemically receiving information to establish stronger neuronal growth in the Hippocampus like you were before. The connections between neurons in each region of the brain start to disappear as the neurons of the auditory system die out and disrupt the connections. I'm mean really, yes a sense like sight gives you the ability to express feelings of happiness as your brain visibly process movements and colors, but nothing is like our ability to "hear" sound. Sound is SO complex. There is SO much more information involved in sound and if you have the correct nerves to emotionally process it, you are going to feel good from the frequencies your hair cells pick up. It's the DNA we have and the functions of our brain that give us the wanting to survive in this world. I believe that damage to one's hearing or in other words, damage to the auditory nerves that allow neurotransmissions, causes the brain to switch it's course of actions. If not fully damaged, it's not going to logically process information yet. But the more you lose these in-going nerves of the auditory nerve, the more your brain loses part of it's strong connection to the limbic system (ex: amygdala) the more the brain will switch to using the Frontal lobes. This was discovered by a researcher apart of the University of Illinois speech and hearing science program. Here's where I believe the terms depression, cognitive deficits, stress, anxiety, etc. all come into play. The brain's plasticity can only go so far. If your brain was wired emotionally from birth, then you processed information through your hearing as you aged. If you were born with a logical brain, then you didn't have the wiring of neurotransmitting nerves/neurons from your limbic system to your inner ear. An emotional brain received it's information from it's ability to pick up sound. Damage to that ability to emotionally process information through sound causes a hole to be established. The brain's plasticity can't fix that hole. That's why in Alzheimers, it's said that the brain loses matter from the inside and towards the outside. It's not emotionally creating enough neurons to keep it's matter continuously growing. Those who were born with a logical brain, I believe, were wired from birth to emotionally experience and process this world and make decisions much more from their frontal lobe than the limbic system. It's the amygdala that allows emotional brains to recall and decide what to do. Fight or flight as it's called. It also has to do with the brain's sexual processing abilities but I won't talk about that.

Sorry if I didn't really answer your question but I like to type out just what logically flows out of my brain now. Still trying to understand what has happened to my brain through my "hearing damage".

I was born with an emotional brain, now with what happened, I experience the world logically. It's my quest to get back to the old me. That motivates me into figuring out new information about the brain, one's hearing, and emotions.

We don't all start out equal - and we don't end up equal.
But everyone has some sh*tty deal they have to put up with.
Tinnitus is our black lung

The connections between neurons in each region of the brain start to disappear as the neurons of the auditory system die out

While I agree to some extent with your theory, I question that the neurons of auditory system die. Or if they did, the brain must have created new ones otherwise we would not hear all these noises.

@jeanoroid ,

Not everybody.

and I'm a twin and she's fine.

I just thought evil twin..

I feel the nervous system has a lot to do with it, something to do with the fight or flight response maybe? Could also be people are more aware than others. But people who are mentally more aware have their genes passed down (natural selection) I'm guessing more and more people will get tinnitus as genes are passed down. Then they'll have to find a cure ))))

Definitely has to do with the fight or flight response. Those who have developed ringing in the brain were subjected to a change in emotional processing regarding the use of their amygdala and frontal lobe. Those that had the ringing, it can simply be put as, "logically" heard sound. My input on this research is that people with no ringing or normal hearing simply hear sound "emotionally". As I explained above in another comment, there's a reason why some hear ringing and other don't as they age. I theoretically believe that young or older adults that hear ringing, were born with a brain that emotionally processed information through their "hearing". The subject either damaged their hearing ever so slowly over time resulting in minimal bouts of ringing that could of been shrugged and later disappeared through neuronal death or they damaged a good amount in a short period of time, resulting in loud distinguishable ringing inside the brain of the subject. I theoretically believe this is all depending on the in-going or out-going nerves that they developed as an adolescent which allowed the brain to chemically receive information through "emotions" that fueled their brain's health. I'm really not sure how the brain functions for those that were born with a different emotional processing system, which can be easily looked at for those who never were able to enjoy music in their lives. Music holds a level of energy that touches each frequency of our auditory system. I believe it's rhythmically in tune with how our brain functions. Our brains love perfection. Music includes so much perfection of time, movement, and information that those with the ability to emotionally process information through the auditory nerves of their hearing system absolutely adore it. Or can say they have a strong connection to it. It's why those with Alzheimers seem to come alive when introduced to music. It seems to be the only thing that barely connects them to their past. I have a theory as to why Alzheimers is not a result from beta-amyloid plaque build up or any other sort of neuron/brain cell destroying processes that take place. There is a hidden cause to it and I believe those have Alzheimers were those that were born with an emotional processing ability through their hearing. It was their brains way to experience the world and create new emotional memories everyday. Those born this way and developed their brain this way need this emotional processing and I believe the hidden loss of causes their brain plasticity to change overtime and lose its ability to properly create new chemically induced neurons and brain cells. I won't dive any deeper into it but I would also like to say that Schizophrenia and Alzheimers share the same brain region that falls apart supposedly from the diseases and not by another reason. Also Schizophrenia is linked to the same loss of brain matter as those with depression, bi-polar, and addiction.

Sorry, I like to get off topic, but I feel like it's best to explain all this because I believe there is a hidden link to all these and just how important it is for ones brain to be able to emotionally process information through their hearing and not just through the hair cells that pick up frequencies (although they are needed to pick up frequencies in the first place).

I have two simply defined articles that should help explain your two questions. The first talks about auditory nerve fiber damage through loud noise, thus resulting in retraction of spiral ganglion neurons back to their original location inside the brain. The second talks about new out-going (efferent) nerves that take the place of lost in-going (afferent) nerves that were once attached to the hair cells of the cochlea. This study gives reason to why some have trouble hearing with background as the the in-going nerves allow one to clearly emotionally process sound when hearing. So yes, the brain does create new nerves to take the place of damage ones, but these nerves don't function properly although it will allow one to "hear". If all in-going nerves have been slowly lost and have been replaced by out-going nerves, then that subject's brain will not be able to emotionally process information anymore from their hearing and therefore theoretically could be the reason why diseases like Alzheimers or Dementia take place, because these in-going nerves allowed the subject to create new emotional memories from information and also allowed them to retrieve memories through synaptic connections in the amygdala, hippocampus, etc.

2) http://www.hopkinsmedicine.org/news...y_new_contributor_to_age_related_hearing_loss

By sending out new nerve fibers which aren't in-going like they were before to make up the auditory nerve, the brain starts to process sound logically as it changes to the frontal lobe. This change in emotional processing has been understood by researchers at the University of Illinois speech and hearing science program. Ones amygdala played a big role in emotionally processing information from their hearing if they have developed "Tinnitus". Most importantly, the as the brain "adapts" to having this inflicted damage to it's chemical processing abilities, it will use these newly connected nerve fibers to process sound causing the subject to not "hear" ringing as much. That's why people on this site state that they can hear their ringing more in exclusively in a very quiet room with no sound to be processed by their brain. Our brains are information seekers and sound is information.
