So sorry about that - I thought she might have a problem at a casino concert. I test audio input against audio output as part of my job, and amplified output usually adds several harmonics to the output. That is, someone sings an A (440Hz) into a mike and out comes 110, 220, 440, 880, 1760, etc. Those aren't the actual numbers but they give the right idea. Harmonics add volume and the feel of a concert hall vs. a solo in a cornfield.
My tinitis is very very mild, and lately the only time it has kicked in was at Conflikt concerts. I don't go to major concerts for the same reason eleyan says.
