This is inspired by the "booed at blues festival" thread. I've heard some people tell me things are loud when in reality, two can carry on a conversation without issue while the music is playing. This is opposed to "Actually" loud where, for example, you can't hear anything else. You can't hear your phone ring and the person next to you has to put mouth to ear to be heard. "Stupid" Loud is the point where pain is caused. For example, air-arcing is loud enough to cause damage. A dimed Vox AC30 or a Plexi on ten through a full stack is also in that ballpark. I have a friend who saw Van Halen live, and he and a large group were right in front of the mains. He told me the concert had a first-aid stand that started handing out cotton and ear plugs. I once saw a "battle of the bands" event featuring 6 hard rock/heavy metal bands playing in a venue slightly larger than the average basement. The event went from 7:30pm to about 1:00am. My ears still were ringing and my left ear was numb by 6:00pm the next day. These definitions are mostly my opinions. I guess the point I'm trying to make is that some people call something "loud" when it truly isn't, and some really don't know when enough is enough. What do you guys think? What are your experiences? Thanks.
