FWIW, recording engineers usually listen at about 82dB.
Learsfool, I'd be interested in clarification of what that means. Average level or the level of short-term peaks? And wouldn't the figure vary depending on the dynamic range of the music? A highly compressed rock recording that has perhaps a 4 db difference in volume between the loudest and softest notes would figure to be listened to at a very different setting than a well engineered classical symphony where that difference may be 30 or 40 db. The symphony tending to be listened to at a significantly lower average volume but a significantly higher peak volume.
I find the OP's question to be unanswerable without some idea of the dynamic range of the music being indicated, and without peak or average being specified. As RRog said, "It depends on the type of music."
