Max sound pressure (measured)
91.4dB5Measurementdxomark.comRead 23 October 2026DXOMARK, 2 February 2021, firmware 0.1.3, tested with a Motorola G8 over Bluetooth: SPL at maximum volume in dBA. The highest of the six test signals is 91.4 dBA with correlated pink noise. The others are 87.3 (uncorrelated pink noise), 86.2 (hip-hop), 81.3 (classical), 86.3 (Latin) and 80.1 (Asian pop). The page gives no measuring distance and says maximum volume is somewhat softer on battery, without naming the power source of the table. The value is A-weighted and comes from a pink noise signal.
