Well, Stu, it may not be that the bodhran was that loud. It may be that you have lost hearing in the high ranges where the flute plays.

I went to a talk about tinnitus recently, and the audiologist said that tinnitus may be the brain's attempt to re-create what damaged nerve endings cannot tell it anymore. If you have suffered damage to the nerve hairs that transmit high frequencies, then you may get tinnitus and you can't hear the high sounds.

That is why it is so important not to blast people with loud sounds.
