Fifteen minutes at 100dB is said to cause potential permanent hearing loss. I suspect 45 minutes at 90 would too. Certainly not an expert in the matter but as one who has whacked his hearing with loud music, guns and tractors....I don't listen at 90 dB for very long anymore........ just trying to protect what I have left.
For me 'loud' is usually around 80 dB and about as loud as I want it anyway. For most typical well recorded music that is a little past halfway on my volume dial. For over compressed stuff (everything new) that is about 1/3 on the dial. Usually listen at around 60-70 according to a smart phone dB meter (probably not very accurate but close enough).
Was recently at a small venue concert. Around 115 dB the whole hour-and-a-half show. I wore ear plugs. I saw a few others with plugs too...but not many. When I was kid I saw Foreigner. Ears rang for nearly two weeks after the show. Ironic that a wannabe audiophile (me) ruins his ears listening to music.
