Surely the sound level that matters is that 1m from the speakers? If that is kept within H&SE limits the other levels will follow.

If bands want noise, then turn up the stage monitors, don't punish the punters.

The reason the sound people get so little negative feedback is that those of us who like to hear the instruments, and their dynamic range, are fed up of commenting that there are other settings than 11 on a fader.
