Back in the day, when I was in high school and college, I was a drummer in some locally-successful rock-and-roll bands, and of course, we played our music way too loud!
It’s a rare live performance I’ve attended where the volume level does not exceed what the room (and/or sound reinforcement system) can handle, for me a big negative, enjoying the live music.
I joined my son at a Trombone Shorty concert at a large club at the Montreal Jazz Festival. I could see the horns playing into the microphones, but couldn’t hear anything that resembled the sound of a horn. I could see the singer singing into the microphone, but could not hear anything that was being sung. When the waiter brought me some foam earplugs, it was not so painful to be exposed to this volume level, but I still could not hear any of the individual instruments or vocalists. I suspect the volume was so loud that the standing waves overpowered the music.
We have an awesome concert hall near me (the Strathmore in Bethesda, MD), where the sound people really have the right idea, it’s loud enough to be exciting, but not so loud to detract from the experience and cause hearing damage.
I found some really good Youtubes on hearing loss:
It would be interesting to see what others have to contribute to this discussion.
