Didn't the Mondays boast the biggest rig this country had ever seen for one of their tours in the early 90's.
Thing is, you only really notice something is loud when it's distorted, don't you? The back-room of the Ministry of Sound surely boasts the most hi-tec sound system anywhere in Europe but you can have a conversation with someone in there cos the sound resonates so cleanly. It only becomes a problem to the ears when the noises is muddied, no? And that's when you can't hear yourself think?
Mind, I saw Chris Cunningham DJ at the Queen Elizabeth Hall earlier this year. Ladytron were on in the main room but he was in the foyer. I've no idea how the fcuk he did it, or even to describe what he actually did, but somehow he dropped the sound at one point as if the entire room was collapsing in. Almost felt like you were nosediving in a plane! I saw people visibly duck and some turned to run away. Felt like your entire head was caving in. Very memorable moment! Never seen/heard anyone do that before.
Comes down to the frequency content. Human hearing is most sensitive around 1-5KhZ, notch those frequencies out, and people can talk amidst armageddon.
Also, sensetivity to those frequencies changes as you get smashed. I used this to great effect any time I was baby sitting a club rig....you put a HUGE midrange cut into the EQ at the start of the night, meaning that as folks come in, the bass is BOUNCING and there is good top end detail, but 1. people can converse, and 2. you have all that midrange to feed back in as people get wankered, which gives the impression of turning the whole lot up, even tho it was already cooking at the start og the night.
BTW, a swept sine wave will do what you describe if it is loud enough. I would wager that with no more than about 2KW of speakers I could phyically knock you off your feet with a test tone oscilator or me Moog.
