Metadata#
- Note
- the frequency weighting or the width of the frequency band used should be indicated; for example A-weighted sound power level (L_WA).
- Remark
- The sound power level is describing the noise emission of a machine and independent of the environment in which the machine is situated. It allows the selection of quiet machines and is a key quantity to carry out a forecast of the resulting sound pressure levels when placing a machine into an environment
