Since my home is situated on a 1/3 acre property and there are copious amounts of insulation in the walls and ceiling, I am fortunate enough to need not worry about bothering the neighbors with my music. This was, of course, by design.
When I’m busy with other things, background levels are fine, as lower volumes don’t pull my attention away from whatever task is at hand. But when I’m relaxing in my listening chair and focused on my music, I prefer an average SPL in my room that produces a lifelike representation of the recorded instruments and vocals.
The graphic below is a frame grab of a jazz piece played back at my usual "focused" listening level using Z-weighting (essentially unweighted, so a more accurate reflection of the actual overall volume in the room without compensation for the nonlinearities human hearing). A-weighting would have resulted in values about 20 dB lower.
For those who can’t decipher the banner text in each quadrant of the image:
- Linst = Instantaneous SPL
- Leq = Average SPL during the measurement run
- Lmin = Minimum SPL during the run
- Lmax = Maximum SPL during the run
The dynamic range is indicated by the difference between the Lmin and Lmax values
