ohoh! db...
I know that car system know a days can go realy loud (high 150db). Tonight i went to a friend and just for fun we wanted to know how many db my sounds system could go to...tested it out...ends up goes to 130 db or so...after we stop cranking the music up... got back home and look at a couple site... 130db can really damage your hearing...
I am just thinking here...my set up is nothing special 2 10" kappa 4 gauge wiring kit, FS vented box... Alpine MRD-M1001 amp... if this set up can get in the 130db range and really damage your hear what can happen in the long run... and what the hell happens to you crazy **** which have better sound system then me...are you guys all DEAF!!! (sry had to yelled that out so you guys could hear me
)
anyways here a few facts i found on the net... from know on i wont crank my music as loud to show off.... not really worth it is it
-When the noise-levels reach 115 dB our ears should be exposed to them for less than 30 seconds a day.
-Noise levels at 130 dB damage your hearing, if you are exposed to it for more than one single second a day.
Dosage = Intensity x duration
82 dB 16 hrs
85 dB 8 hrs
88 dB 4 hrs
91 dB 2 hrs
94 dB 1 hrs
97 dB 30 min.
100 dB 15 min.
109 dB 1 min.
It is important to note that 110 dBs is a lot louder than 100 dBs because the dB scale isn't linear, it's logarithmic. Every 3 dB's doubles the level
also i am wondering if people here actualy found a diffrence in their hearing capacity...

i may be wrong but i think 130 db high pitch or low pitch is still 130... 130 db will damage your hear... 130 from a high or low frequency is still the same pressure to your inner ear... may be wrong tho
for the comp i know they control from outside their car...lol but still when you guys are driving dont you crank up the music sometime or are those big subs only for comp?

The tweets definitely get to me before the bass does. But I am with audiofool, I stopped crankin my system cuz I don't want to be def when I am 50. If I am rollin with my friends I make them turn the music down, they will thank me later.

There is no known risk of hearing loss associated with sound levels below 70 dBA, no matter how long you are exposed to the sounds. However, as sound levels increase, the duration of daily exposure becomes an important risk factor for hearing loss.
