Re: hearing sudden distortion effect

Jim, Tom, and others,

There is no established term for this. One might call it a phenomenon of transient hyperacusis. Tom's suggestion that endolymphatic hydrops (EH) may be the cause seems plausible. It is known from research in Meniere's disease (MD) that EH precedes MD and often remains subclinical (not leading to MD). It may cause transient vestibular or cochlear distortions. The combination of loud sound with EH is a strong candidate for causing cochlear distortion. The described case need not be a dramatic sign at all. Ear plugs at hand in noisy settings might be all that is needed.
