I think what you mean is Hyperacusis or misophonia or did you actually mean ringing in the ea...
I've seen an anecdotal account of a musician who contracted severe Menniere's (ringing in ears
combined with dizziness, hearing loss) after a period of severe stress (not PTSD). He found a
way to bring it into remission with an interesting and rather exacting protocol of diet, meds, and
supplements. And reducing stress. Meniere's Disease - a success story and treatment plan - Joe Bongiorno
Might be the common denominator is stress and concomitant poor diet, sleep, etc.
