Notes:
1.  LWAd is the statistical upper-limit A-weighted sound power level (rounded to the nearest 0.1 B);
2.  LpAm is the mean A-weighted emission sound pressure level measured at the 1-meter bystander positions (rounded to the nearest dB);
3.  10 dB (decibel) = 1 B (bel);
4.  All measurements made in conformance with ISO 7779 and declared in conformance with ISO 9296
