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
