ThomasL - try earplugs. You don't actually need to LISTEN to the tones to read the SPL meter But I know what you mean. The S&V disc pretty much concurrs with your statement - basically, as long as the speakers are set evenly with respect to eachother, the sound will be ballanced, regardless of volume. 85db or 75db are what one is shooting for, but that does not mean you will ever really listen to it at that level.
