Totally untrue. Decibels, also known as sound pressure levels ( spl's ) is the same. Meaning 150 bd at 80Hz is the same as 150 db at 18kHz.

150 decibles, is 150 decibels period.

It is the pressure, of the moving of the air causing the damage not the frequency.

I've always heard from a bunch of people in the business that higher frequencies will damage your hearing a lot faster than lower ones.

the rumor- because higher frequencies vibrate the eardrum faster, they will do more damage than a lower frequency at the same volume. in other words, a tone at 9000Hz @150dB will be more damaging than a tone one octave down at 4500Hz @150dB. while it makes sense to me, i have never seen actual proof to back it up. so, until i see some evidence, it will be a rumor to me.

and since i seem to be one of the "older" audiophiles (im 28), ill go ahead and tell you all what you dont want to hear. you are gonna have bad hearing, period. i already have sustained permanent hearing damage from past car audio, and my loudest system EVER only hit a 141. prepare now. i never listened to my system cranked for extended periods, but i never had earplugs either.

nothing wrong with going as loud as you can, and God knows i love 1/0 guage cable and a pair of Optima's. but please, be careful. saying "huh?" all the time really sucks. take it from someone who's "been there, done that".

db measurements shouldn't be taken shile you are in the vehicle, with that said, i hit a measely 136.6 last year with the fosgate 15.

Again it is the sound pressure level that is doing the damage.
Granted you FEEL the high frequency's more for the exact reasons you stated. Either way 150db is 150 db
20Hz to 20kHz.
I am no audiologist, but I have studied audiology.
I own my own business ( part time ) in concert event productions. Meaning setting up and running concert PA ststems. There is a pretty good living in that field, so I am very protective of my hearing. I visit my audiologist once every year for a hearing screen and we frequently discuss my line of work and the hazzards involved. So I have my information from a good source.

Ya that was a concern for me, and still is. So I put in a crime gaurd alarm (cost me a little over $400) then put 5% tint over the factory tint on the back, you can't see anything.

Good idea. Sounds like you got it covered. Check your insurance too, just in case. Sometimes they won't cover aftermarket items.

The human ear is much more sensitive to midrange energy than to low freq energy. There are charts that depict this uneven sensitivity pattern known as the fletcher-munson curves (This is proof.. not what some guy claims )

The human ear does have little hair like devices called scilia(sp)that are in reality nerve endings. They react to the vibration of the air, at high freq they vibrate quickly, and with very high amplitude(dbs) they can be permanantly damaged VERY easily.

On the other hand, low bass energy has very long wavelenghts, and lots of displacement, so they tend to cause these scilia to 'lay down' instead of vibrating like mad. This will cause a temporary hearing loss, until they return to normal, and over time can cause hearing damage, but NOWHERE NEAR the scale that midrange energy does.

bruce- im not doubting you.

MONMIX- im not doubting you either.

no matter the case, take care of your ears. im not saying dont turn it up, just take care of them. you know what you have to do. i wish i would have.

Insurance is covered, i got a rider for my system.

If I'm not mistaken, permanent hearing damage can occur at far less than 110db. All ranges will cause damage - just in different ways. High frequencies will tear an eardum - similar to running high frequencies through a woofer - tears the cone. Low frequencies will pop the drum - usually around the edge of the drum - like blowing the cone out of a woofer. I love the noise as much as anyone, but when is enough enough? To me the noise is not needed - just like the guys/gals driving around in lifted chevys that have never seen any dust!

Seriously - be careful around that high level of noise. A 737 on the tarmac is about 120db - scary to think a stereo is louder than that....

Yeah, I guess that sums it all up reguardless.
Well said.

FM, yeah you are right 110db WILL hurt you, but 120db will hurt you faster. 90db will hurt you, 80db will even hurt you if exposed to it long enough.
We have gone through this before and I really did not mean to derail this thread. ( Sorry AirKevin )
I know better than to suggest no loud stuff, but all I am saying is, please be aware of what you are doing to your self. Just be careful. Moderation is the key.

Speaking of moderation:

I don't mind, I find it interesting.

 

[white96x]

i want to know what everyone else is hitting at-maybe i'll get mine tested this weekend for fun!

 

[BruceWayne]

local shops meters are always high... im waiting for a comp near me just to get metered, and possible win a trophy ;]
