Headphones and Hearing Loss

[iceblitzed]

Hello Tom's Hardware Forum

I am not very familiar with the headphone world. I recently read articles that keeping the sound of your speakers/headphones etc below 85 decibels will not cause hearing loss (or very little). I was wondering if there is some program or something to determine the decibel rating that is coming out of headphones?

There are sound level meters, or perhaps not quite as accurate, cellphone apps. You'd hold the meter (or phone mic) up to the headphones to do a measurement. Not many people probably go to the length of purchasing a meter for this purpose but don't listen at a higher than comfort level.

A thread at another forum: http/www.head-fi.org/t/607728/testing-headphones-decibel-level

For a rough idea, here's a chart that lines up 85dB with "city traffic (from inside a car)" with 80 dB as "telephone dial tone" and 90 dB "train whistle from 500 ft or truck traffic"

I wouldn't know where to look up that sort of specification (it's not the sort of thing ordinarily published). Why do you feel you need to know this?
