The first tinnitus tone I got in my ETD sounds like a high pitched whistle and I've heard form those with noise induced tinnitus have the same tone so I'm inclined to believe that it's from that (plus I already had slight high frequency hearing loss from childhood thought that never gave me tinnitus). I just feel kinda stupid for getting the T to be honest. :/
I think most people have some degree of hearing loss though, and that its normal as we age..
I remember when I was a kid, I found that when I took a hammer and softly knocked it on a metal plate (a sound that was not very loud at all), I got this high pitched solid tone in my ears, and afterwards the tone morphed into a hiss, and then it went away (and the only way to trigger this by a soft/low sound was that the sound had to be of a very sudden onset and I kind of had to have the expectation of the sound). When that happened I could clearly feel physical movements inside my ears, and I was so intrigued by that. I didnt know much about the ear at that time, but I did realize that there was some kind of a protective mechanism that was operated by muscles inside the ear and that it was able to produce both a solid tone and a hiss most certainly without damaging my hearing.
Also when I was yawning I would get this hiss in my ears. I have read a littlebit about it, and it seems to be pretty common indeed, but I cant find any solid conclusion as to why this happens. Some believe its because of nerves being pinched by muscles when the mouth is kept open, some believe its because of pressure change in the inner ear, some believe its the muscle spindles or the golgi tendon organs, I believe its because of a pull on the temporal mastoid process caused by the suprahyoid muscles and possibly the lateral pterygoid muscle that affects the alignment of the middle ear ossicles, but cant say for sure.
My sister got a high pitched whistle in her ears when her neck was tired, but it went away when she tilted her head.
I think we have a lot to learn when it comes to tinnitus, and in many cases, if not most, it could be that theres something else at play than the good old broken hair cell theory. The potassium channel theory is interesting as well, but I suspect that the "abnormality" in those potassium channels could exist in most people with tinnitus, even if they are related to the outer / external ear, middle ear, inner ear, muscles or the DCN (if that theory has something to it) as it seems like those channels are one of the last pathways the auditory signal propagates (if that is the correct term) before it enters the limibic and auditory cortex (please correct me if Im wrong).
I think that the some of the potassium channel theory could be put to the test if one compared the potassium channel activity in two individuals, one with tinnitus, and one without. Then replicated the first persons tinnitus and played the sound through an earbud or headset into the ear of the individual that originally did not have tinnitus.
I think tinnitus related to the tympanic membrane could be put to the test by comparing sound vibrations on both sides of the tympanic membrane to the microscopic scale, and tinnitus related to the middle ear could be tested by comparing vibrations of the tympanic membrane against vibrations of the oval window. I would think that could provide clues about the tapping of the ossicles as well.
I suspect that intermittent / fleeting tinnitus is related to middle ear adjustments, including the tympanic membrane, and could be put to the test if one was able perform functional imaging of what changes that took place in the auditory meatus while it happens (if it has the accuracy needed).
What I also found interesting is while reading through some of the literature, it seems like people that suffers from migraine or migraine-like symptoms, tension headaches or anxiety are more at risk of developing tinnitus, even tinnitus related to noise. This happens to be the case with a number of people I have talked to as well.
Im just thinking out loud, and Im no expert, but I hope that more technology will be made available and more research will be carried out for this stuff
I hope that your tinnitus will go away on its own, and I believe it will die down in time. Lets stay optimistic
It seems like a cure can be on its way as well.
If you are interested in neuroscience, potassium channels and the relation to tinnitus, I suggest reading through some of
@benryu 's posts, as he seems to be one of a kind (thanks for providing all this great information)
