Acoustic Performance
Declared noise emission values in accordance with ECMA-109
| Sound Power Level L W A,m (B) | Sound Pressure Level Operator Position L p A,m (dB) |
---|---|---|
Idle | 1.7 (K V = 0.3) | 7 |
Wireless web | 1.7 (K V = 0.3) | 7 |
L W A,m is the mean A-weighted sound power level, rounded to the nearest 0.1 B.
L p A,m is the mean A-weighted sound pressure level measured at operator position (rounded to the nearest 1 dB).
1 B (bel) = 10 dB (decibel).
K v is the statistical adder for computing upper-limit of A-weighted sound power level.
The quantity, L W A,c (formerly called L W Ad) may be computed from the sum of L W A,m and K v .
