I want to know if type II Outer hair cell nerve fibers send pain signals through the Audiotory nerve to the Dorsal Cochlear nucleus which is then sent to the trigerminal nerve. Then pain is experienced. Hyperacusis with pain is both the trigerminal nerve and audiotory nerve sending pain signals. (noise induced ear and face pain)
What about other triggers for hyperacusis with pain, does hyperactivity in the audiotory brain caused by tinnitus have anything to do with it? Is this loudness, or pain hyperacusis or both?
What about loudness sensitivity in some autism cases or Audiotory processing disorders I believe "loudness hyperacusis" is that same thing. Yet loudness hyperacusis also occurs in acoustic trauma sufferers. In Autism and APD is there hyperactivity in the DCN as well?
Outer hair cells are the cochlea's amplifiers, do damaged outer hair cells also cause some noises to sound too loud combined with massive outerhair cell damage activating the type II afferent nerve fibers? But there also have to be a central pathology.
Some people expose themselves to very loud noises and do massive hearing damage and do not have tinnitus and hyperacusis? There must be a neurological gateway mechanism
I really do believe there is a central and peripheral version of hyperacusis. I wonder if tinnitus is the phantom limb sensation then maybe one form of hyperacusis is the phantom pain to compensate for a damaged audiotory nerve.
Because some people experience chronic ear fullness.
I am also convinced there are 2-3 types of hyperacusis
and I do acknowledge subtypes of tinnitus depending on what part of the brain tinnitus is established in.
We don't exactly whats happening know research is not there yet
I look stupid speculating of things way over any qualification I have but this literally keeps me up at night knowing audiologist and ENT's aren't trying to escalate these questions to bio-medical research to help sufferers. They just shill Tinnitus Retraining Therapy without looking into the depths of the problem
TRT'S creator, Pawel Jasterboff is a quack, his research is from several decadesd ago before anyone knew about type II afferent nerve fibers or the role of the trigerminal nerve in hyperacusis.
He never considering looking at the suspected pathologies in hyperacusis and subtypes (pain and loud) and trying to think about how his treatment of TRT would apply to any of them. Once again the research wasn't therea t the time.
He just shilled TRT to the world and obviously predatory audiologist that sell hearing aids for a living would have no problem picking up dogma. Audiology is literally a extremely outdated pseudo-science field
