On reflection I should have written "I know you are aware of this".
All I was doing was trying to make it clear to da kidz who might be reading this that every time they are in a high volume situation they are one step closer to permanent ringing. That it is not all or nothing. Each high volume situation is laying the ground for misery later on. And it is avoidable.
Again, I know you know this. I just wish I knew it when I was in a position to be protecting myself. Ironically, mine started after a quiet rehearsal with an EUB, a harp and keys.
