Loud sounds good to me, but it's bad for me. Probably most people which is why in the 1990s and up, pop music was extremely compressed to sound louder on the radio. That became known as the "loudness wars".
Years ago I knew a drummer (he is now in the 'great gig in the sky') who played standards jazz to the 55+ people in the 1980s. They played small settings, and never played all that loud. Probably at the drum kt about 90-100 db. He kept buying brighter and brighter cymbals because his high frequency was so damaged that he couldn't hear them well.
I think it's OK if we damage ourselves for our craft. It's a freedom. But I don't think it's OK to harm somebody else permanently.
