You are one of the lucky ones then.i know ill get laughed at for saying this, but the installs at my CC are actually pretty darn good. we have some very skilled, knowledgeable people
we cut through the dash and rear deck of a 63 impala and installed 6x9's and an eclipse h/u. sawing through the dash of an antique car aint basic
You're right, a 120 db high piched squeel would definitally hurt my ears real quick, but we were talking about subs in the+3 dB is twice the acoustic power+6 dB is double the physical volume
+10 dB is perceived as double the volume to the human ear
BTW, the "tech" probably confused dB with dBA ... 120 dB @ 50 Hz (90 dBA) is moderately loud ... 120 dB @ 1000 Hz (120 dBA) is very loud ...
Yes it is (if you consider a 24 year old car an antique). I ran all my own wires for my HU in my 81 buick. The 12v+ constant, the 12v+ ignition, the ground, the speaker wires to the doors (through the factory gromits), and all the wires going back to the trunk in one day. And on top of that I installed a viper alarm myself (first and only time) within 4 hours.we cut through the dash and rear deck of a 63 impala and installed 6x9's and an eclipse h/u. sawing through the dash of an antique car aint basic
ish, well i must be superman then, because i roll around daily listening to music at over 130 db's //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gifSo I went to best buy today to see if we could pick up some speaker ends ($5 for 4, I passed it up), and we decided to test the subs they had, and the tech guy came to help us. It was quit comical"
Him: "120db will make your ear drums explode and you're ears will bleed, exceding 110db is very dangerous."
Me: "Don't bandpass boxes peak at a certain frequency, and sound bad at others?"
Him: "No, they perform very well at all fequencies when they're in a trunk, only in open air are they loudest at one frequency."
Him: "One more db is twice the pressure on your eardrums." (that might be true, I don't know, but it doesn't sound right.)
I'm not exaderating any of those quotes, that is exactly what he told me.
i wouldn't think so, it may cause a short period of "deafness" but thats about it.cant 120db's at a high frequency like 5k plus make you go deaf?
if you could stand listening to it for that long, normal human reflex would be to turn the hand counter clockwise......or if your at work just put in ear plugsYes ... Approximately 3.5 minutes @ 120 dBA will cause permanent hearing damage ...
