I'm glad to hear you have an appointment, this is the first step. The
next is a complete audiological evaluation by a certified audiologist.
Yes, a concert can cause hearing loss -depends on a number of factors. We
do not fully understand individual susceptibility to noise induced hearing
loss. The Air Force currently requires its musicians to wear hearing
protection in practice. Most older rock stars have losses. A few are now
"out of the closet" and endorsing the idea of hearing protection. In a
few years, they may be endorsing hearing aids like some do food chains.
