[QUOTE="T3mpest, post: 2432657, member: 560148"] I was that bored, 180db is about 3psi. That's hitting you, oh 60 times per second, yeah that's pain. Plus since decibels go up exponentially, by the time you hit the 194 barrier, your dealing with almost 15psi! Looking at the derivate, around 170 decibels is where the pressure vs SPL begins to get interesting. 1 or 2 decibels of increase at 170-180's actually means something in terms of pressure vs say 140-150, both of which are well under 1 psi. So yeah, if a car hitting 170 wont' hurt you, a car hitting 180 very well might! Just due to the nature of decibels. It's exponential growth, to put it in perspective, your under 1 psi up until 170! 0-170 decibels is all under 1 psi, 170-190 contains the other 14psi! The difference between say 180 and 183 is STAGGERING, simply because of what kind of pressure it takes to make 180, it takes 2x that already enormous pressure to gain 3db's again. Setting in a 170 car, is piddly shit compared to a 180 car, just due to the fact that your moving well over 6x the air. [/QUOTE]
