My room is in the 30’s when there is no traffic, goes up to the 40’s when there is traffic nearby.
I don’t particularly listen to my music loud, I usually listen in the 63 – 73 db range. Occasionally I go above the 73 db range, but I value my hearing so I tend not to go there for too long.
If I could keep my room in the low 30’s range all the time, there would be no need to play loud at all since I would not be fighting against the background noise.
