Acoustic Performance

DECLARED NOISE EMISSIONS in accordance with ISO 9296

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 sound pressure level measured at the operator position (rounded to the nearest dB).
3. 1 B (bel) = 10 dB (decibel).
