@atpfm 2 feedbacks: 1. Apple has privacy.apple.com to export data (maybe just for CA and EU?). Trying now to see if it includes messages under “other”.
2. Research shows as overall volume decreases, bass frequencies are perceived quieter than high frequencies which is why some speakers try to bass boost at quieter levels. https://en.m.wikipedia.org/wiki/Equal-loudness_contour
