Ear Damage: High Frequency vs Low Frequency's?

Yeah i was just wondering... do high frequency noises damage ears easier than a lower frequency noise would? ie... with my stereos... and any other stereo i've listened to it seems that my ears are more sensitive and get annoyed faster with higher pitched noises over lower pitched noises.. so basically what im asking is, is it easier and faster for higher pitched frequencies to damage your ears than lower frequencies?

High frequency's take much more of a toll on your ears than low bass frequencies

I think the frequencies hardest on the ears is somewhere around 2,000hz-4000hz...

Yup. We're most sensitive in upper midrange, think babies crying, nagging wives (or at least occuring harmonics from them), things like that ;)

you know whats really hard on your ears double comp set up front with about 400 watts on them playing a couple dimebag solos and youll have ringing for a couple hours. i got a cop that came to my shop cause i was showing someone my mids one day and they were too loud. boob car boys get in trouble with subs i get in trouble with my mids.

Horns. Horns straight out HURT. They stay clean at high output, though.

Anyhow.

I posted the OSHA Guidelines on another forum.

In the OSHA CFR (Code of Federal Regulations) 1910 General industry there are 7 pages about "occupational Noise Exposure" and its VERY extensive.

TABLE G-16A
