Notes:
1. L is the statistical upper-limit A-weighted sound power level (rounded to the nearest 0.1 B).
Wad
2. L is the mean A-weighted emission sound pressure level measured at the 1-meter bystander position
pAm
(rounded to the nearest dB).
3. 10 dB (decibel) equals 1 B (bel).
4. All measurements are made in conformance with ISO 7779 and declared in conformance with ISO 9296.
Measured at 25° Celsius at a 500 meter altitude.
