Db is Db, yes lower fq hurts you more, but stand under a 747 when its landing or taking off you'll see what I mean, its friggen loud.
Yea, I know installers who are now deaf from playing around with too many 150 db systems, your not immune.

No argument there, jet engines are loud. I've been to an airport before. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

What I was stating is that 140 dB @ 10000 hz is much more damaging than 140 dB @ 40 hz. This is common knowledge.

So actually your post is incorrect unless you meant to agree with me that HIGHER frequencies hurt more/are more damaging.

I can't think of one person that would stand next to a jet engine without going deaf basically instantly, but thousands of people will listen to a 140 dB car stereo all day long and never have hearing problems.

No one knows. That shit's just too hard to calculate without being a rocket scientist.

CotJones, I think that you need to get out in the real world more often to see what it's like.
