I had a small recording studio for a while, and used to engineer bands. It really doesn’t have to be that loud, and it’s usually better when it’s not.
It always bugs me when I go to a gig, and their engineer has just cranked everything up to 11. At that volume, you just wash out the sound. There is no finesse, no separation of individual frequencies and instruments, and all you get is hearing damage. One gig I went to had my ears ringing for 3-4 days afterwards, and I still have frequency loss in my hearing.
Bright lights bug me. There have been times where it has been painful to me. But I’ll generally just leave, or not put myself in that position.
At home, I leave most if not all of the lights off at night. If the TV is on, that’s all I need.
