I'm currently using Foobar and AD700s, I was wondering what would be a safe volume to listen to music at? I listen at -5.17 db and it feels like a concert in my ear.
I like driving along to loud music though so I'm guessing my car is over 95-100db+
OSHA TABLE G-16 - PERMISSIBLE NOISE EXPOSURES (1) ______________________________________________________________ | Duration per day, hours | Sound level dBA slow response ____________________________|_________________________________ | 8...........................| 90 6...........................| 92 4...........................| 95 3...........................| 97 2...........................| 100 1 1/2 ......................| 102 1...........................| 105 1/2 ........................| 110 1/4 or less................| 115 ____________________________|________________________________ Footnote(1) When the daily noise exposure is composed of two or more periods of noise exposure of different levels, their combined effect should be considered, rather than the individual effect of each. If the sum of the following fractions: C(1)/T(1) + C(2)/T(2) C(n)/T(n) exceeds unity, then, the mixed exposure should be considered to exceed the limit value. Cn indicates the total time of exposure at a specified noise level, and Tn indicates the total time of exposure permitted at that level. Exposure to impulsive or impact noise should not exceed 140 dB peak sound pressure level.
Guys, you CANNOT go by what any player tells you - it has no real way of knowing how loud the sound is, because it has to know the efficiency of the headphones in order to calculate it! Maybe the Apple one would be accurate ONLY for the Apple-supplied earbuds, but that's all. Otherwise, you have to use an SPL meter to measure.
