I read in another FAQ that if I send you my earphone model and inform you that I am using an ipod (which I am), you'll be able to let me know which levels are safe for listening without damaging my ears.
I have the SE210's and a Third generation iPod, I would really appreciate it if you could help me determine which levels are safe!
In the United States, the safe listening level for 8 hours is 90 dB SPL (Sound Pressure Level).
The SE210 has a rating of 114 dB SPL with an input level of 1 milliwatt. Working backward:
.5 milliwatt(mW) = 111 dB
.25 mW = 108 dB
.12 mW = 105 dB
.06 mW = 102 dB
.03 mW = 99 dB
.015 mW = 96 dB
.007 mW = 93 dB
.0035 mW = 90 dB
Now you must ask Apple this question: What setting on my Ipod will deliver .0035 mW into a earbud with an impedance of 26 ohms? Apple's answer will provide the setting you seek.
