For me my listening levels vary all over the place, when I am listening late at night which I often do, levels are very low probably no more than 60-65 dbA. During the day, when there is not a concern about disturbing anyone, those levels can have 100 dbA peaks, though I never listen at those high levels for very long. Long term levels at loud volumes 80-90 dbA but even that is not continuous. Already sporting measurable hearing loss, I am trying not to make it any worse than it already is. That said, when I am practicing trombone, which I do almost daily, the SPL easily exceeds 100 db and while it is possible to reduce the level a little bit, its not easy to play much quieter than that.
