I honestly don't totally agree that it does. I have had a few VERY loud systems for daily. My last one was doing a 156 on a lab outlaw and did around a 151 at the ear. Lets take at the head measurement. I listened to this many many times full volume blasting ... A rock concert speaker which I believe is around 120db will tear your hearing up pretty quick. And 150's is well over 100 times louder(even with the other argument about perceived on here lol... pure pressure over 100 times that of the rock concert speaker on the ear. I think the freq matters. The reason I say this. I am 26 and they say the average person I think over 20 can NOT hear over 17khz I can did some hearing test and I can for sure hear up to 20khz. This is after riding around MANY days at pressures FAR exceeding that of a rock concert. I have friends that have massive hearing loss with very little/no bass BUT with overbearing highs. I have NEVER used LOUD highs. Now I know on a perceived scale to the ear the higher freq's are louder. But i wonder what causes the damage. Is it the faster movement of the ear drum. 8,000 times per second as opposed to 50? lol. again theories here. I can recall many times getting out of my loudest (explorer) and sit in somebody's car with a bunch of treble and I would jump out QUICK (KILLED my ears) . They looked at me like I was crazy (going whats wrong with you.. you drive that thing around daily. I would be like that thing doesn't have its own rock band in there lol.Would love to hear a few replies.
