1. L is the declared (upper limit) sound power emission level for a production series of machines.
WAd
2. L is the mean value of the A-weighted sound pressure emission levels at the operator position (if
pAm
any) for a production series of machines.
3. <L > is the mean value of the space-averaged A-weighted sound pressure emission levels at the
pA m
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
