Absolutely, the problem is most people ignore the fact that frequency and duration are also vitally important. Listening to a concert for 2 hours at 110dB is quite bad for you and likely significantly worse than a few gunshots because of duration. A gunshot peaks over just a couple milliseconds. A suppressor lowers the sound but increases the duration (among other things) but for high pressure rounds (rifles, etc) its still quite loud.A single instance like that is enough to cause permanent hearing loss and tinnitus. Loud noises are no joke.
That's a bit low, I think. The zone where you should be concerned starts at around 80 decibels.
Noise is a significant source of hearing loss, but you can protect your hearing. An important first step is to understand how noise causes hearing loss.www.cdc.gov
So you have to take the noise level *and* duration into any recommendations. Its why OSHA adds a duration. I think once it hits 140dB OSHA says no sound over 140dB is safe at any duration since 140dB is the range where sudden accute damage can occur.
