Notes about Noise Emission Values:
1. L
WAd
is the declared sound power emission level for a production series of machines
2. L
pAm
is the mean value of the sound pressure emission levels at the operator position (if any) for a production series of machines
3. <
LpA
> is the mean value of the space-averaged sound pressure emission levels at the one-meter positions for a production series of machines
4. N/A = Not Applicable (no operator position).
5. All measurements are made in accordance with ISO DIS 779, and reported in conformance with ISO DIS 7574/4
