I'm curious. What is your "normal" listening volume?

Guys, To simply state a number of decibels is not very informative. It depends upon the distance of your listening position to your speaker, the angle of incidence of your meter, the setting of the meter itself (weighting, etc), how accurately you aim it, if it's at all directional, and whether you use music signal (a mixture of frequencies from bottom to top) or a pure tone (e.g., 1000Hz). Small differences in any of these aspects can make a big difference in the SPL reading.

70-80db

At my listening chair 66 - 72 db. The chair is 9 feet from the speakers

75 db +-10, more or less. Maybe some peaks into 90-95 db when I play large scale orchestra music, but nothing louder than that. I use the NIOSH SLM iOS app to measure.
