I’ve spent some time looking this up, and have been meaning to start writing to anyone who researches midfrequency loss. As far as I have found, the actual research says it can be hereditary, idiopathic, or from vestibular schwannomas. What I also found, though, was info on the mutation of the TECTA gene, DFNA 8/12, which talked about issues with proteins and amino acids.
Look up this link: http://www.ncbi.nlm.nih.gov/pubmed/18575463
I don’t really understand any of this, (and if there are any scientists reading this please explain!) but it seems to me that this doesn’t necessarily mean that the hair cells are “dead,” like I’ve always been told.
What I’d like to know from other cookie biters, is what kinds of issues you have that don’t seem to fit with what we’re told about hearing loss. Like, I’m driven absolutely crazy by noises that it seems like I shouldn’t even be able to hear, according to my audiogram, like breath noises and very faint mechanical/fan noises. And I swear that, if a noise is left on long enough (as opposed to the short beeps of the audiogram), at some point my brain notices it and starts paying attention to it, and then I just cannot habituate to it. I am constantly bothered (unaided) by noises that, when I mention them to people with normal hearing, I get the response, “oh, I can hear that, but I wouldn’t have noticed it if you hadn’t mentioned it.”
Does anyone else have anything odd like that?
