Notes:
1.	L _WAd is the statistical upper-limit A-weighted sound power level (rounded to the nearest 0.1 B);

2.	L _pAm 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

5.	Preliminary Data
