Very funny. High volume is 90+db.
I remember when in my early twenties hanging out at a high end audio store with the two salesmen while cranking their demo system. We chuckling and slapping each other on the back when we were able to see the spl meter hit 120db with their Klipschorns. That’s loud. Sounded terrible. The noise floor was probably 95db.
More than once, at that age, young and stupid. The mark of a good system was it could crank over 100db. Usually not sounding good at all, because of the incredibly high noise floor and tremendous distortion.
These days 65 to 75db is my normal volume. Although once in a great while it is fun to crank it to 85db on some old punchy rock and roll. Fortunately my system sound great at either level. Some youngsters came over to listen to my system and had it cranked over 95... sounded great... as I was quickly vacating the room.
