I think alot of people who buy super loud aftermarket exhausts(not talking about just a shorty silencer on a two-stroke) just don't understand how sound works. Some(maybe most) people don't understand that the decibel scale is not linear, it's logarithmic. So a bike putting out 106dB is not ~10% louder than one putting out 96dB, but in fact it is 100% louder because the human ear judges an approx. 10dB increase in sound to be twice as loud.
As Rich aluded to, low frequency sounds travel MUCH farther than high frequency sounds. IMO this is why we're seeing an increase in track closings of late. Not because four-strokes are louder when you're standing trackside(they are), but because they are A LOT louder far away from the track. Now people who didn't even know there was a track a half-mile away are very much aware of it.
