- Definition
- ten times the logarithm to the base 10 of the ratio of the sound power radiated by the source under test to the reference sound power [W_0 = 1 pW]
- Definition source
- ISO 3740:2000, 3.3; ISO 4871:1996, 3.10
- 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
