scar tissue causing permanent hearing loss, you can return to hear your mix with
fresh ears. The mix should sound invitingly loud, but not painful.
• In basic terms, if you find that you've turned up the high end since the night
began and it still sounds the same to you as it did at the beginning, watch out.
That's not "fatigued horns" or "changing room acoustics" rolling off the high end,
it's your ears. Please do yourself and your audiences a favor - USE EARPLUGS!
And if you can't bring yourself to do that, be considerate of your audiences and
leave the high-end EQ or crossover at normal settings.
