Seems to me there is some difficulty with what a dB is and how it relates to the ability of the human ear, and hearing. 80dB is not very loud at all, but then is 150db loud to a jet mechanic? Not to me- I wear ear phones.
The source may PEAK at 120-150dB, but real music is not a peak measurement, it's dynamic, soft vrs. loud, that is the output level I speak of, not some constant number that means nothing to the listener's enjoyment, or real world or live listening levels.
I wonder if all the musicians on the planet that play live shows at 150dB car hear, um, yes, and some of them own very nice ultra high end systems and tell the diff. when a particular note was missed.
I was a jet mech, and yes, 150dB is painfully loud....
Not sure there are any 150dB concerts around, they's probably be shut down by OSHA. You might find 150dB at a car stereo SPL shootout, a rocket launching pad, or a jet engine test cell...
