Remove iPod European Volume Cap
bsodmike writes "This is a complete how-to for removing the EU Cap in the new iPods allowing 104dB bliss! Thanks to everyone @ #eucap including UnixMonkey, Keaner, Silvacow, m@rk et al." Some countries have an upper limit of 100dB for consumer devices, so the European version of the iPod is "crippled."
It said "140db" cap! Hot damn! If it did that, I'd buy 2 for my car and drive around like a hoodlem.
Actually in most European Countries the Taxpayer will pay for your disability. So it is in the interest of everybody to protect dumbasses from themselfs Just my 2 cents
How much money was spent in the House of Reps. and Senate debating, drafting, and approving this bill?
Since the law is European, my guess would be $0.00.
104 dB is (10^0.4) = 2.51188643150958 times louder than 100 dB.
2B = 10 times louder than 1B
2dB = 10^0.1 times louder than 1dB
got it?

It's not your eardrums that are damaged, but the cilia in your cochlea. These are fine hairs that are vibrated as sound waves travel past them, and stimulate the nerves to which they are attached.
These hairs do not recover from damage. Once the hair is killed, you have lost the ability to hear the frequency that hair was "tuned" for.
You will experience permanent, irreversible hearing damage at 104dB within five minutes.
Decibel Exposure Time Guidelines
Accepted standards for recommended permissible exposure time for continuous time weighted average noise, according to NIOSH and CDC, 2002. For every 3 dBs over 85dB, the permissible exposure time before possible damage can occur is cut in half.
Continuous dB Permissible Exposure Time
85 db 8 hours
88 dB 4 hours
91 db 2 hours
94 db 1 hour
97 db 30 minutes
100 db 15 minutes
103 db 7.5 minutes
106 dB 3.75 min (< 4min)
109 dB 1.875 min (< 2min)
112 dB .9375 min (about 1 min)
115 dB .46875 min (about 30 sec)
Don't fuck with loud sounds. It's just not worth it.

Are you saying loud music is a major cause of baldness?

Shoulda listened Mom...
IIRC, Apple did this because France complained about the 104dB Max volume. iPod sale was banned in France for a short while over this. Blame the French ! :)
This assumes, of course, that they're talking about 100+ dB of sound pressure (SPL).
But that's completely ludicrous. The SPL levels are a function of the speaker/headphone design and proximity to your ears in addition to the power output of the amplifier.
A dB is a unit of ratio between a given level (power, pressure, whatever) and a reference level.
In this particular case, they're probably talking about dBu or dBV or dBm or some other ratio involving output voltage/power levels.
104dBu is not the same as 104dBV which is not the same as 104dBm. Either one can translate into high SPL levels, low SPL levels, or anything in between, depending on what kind of speakers, headphones or other amplifiers are attached.
According to Apple the iPod can put out up to 30mw of RMS power per channel. This is about 29 dBm (20 log(30) ),so it's obviously not what the original article is talking about.
I'm actually rather curious now to know what that unqualified "104 dB" figure is referring to, since every different brand/model of headphones you use will have a different SPL for any given power level.
