How do you know it is 80 dB? Is it dBA? Most people are not very good at guessing a level.
If you’re listening to music at 80 dBA for an hour, I think most guidelines would say that is safe. OSHA says you can safely have 90 dBA for 8 hours a day. This guideline is a bit dated and possibly assumes that the background noise one experiences for the rest of the day is lower than it actually is, but with a 10 dB safety factor and 6-7 hours in difference of length, you are likely fine if you trust OSHA.
