1
Noise emissions in the environment are measured as sound power (L
WA
) in conformity with directive . The
difference between guaranteed and measured sound power is that the guaranteed sound power includes dis-
persion in the measured result and variations between different units of the same product according to direc-
tive .
2
Equivalent sound pressure level, according to EN ISO 19432-1, is calculated as the time-weighted energy to-
tal for different sound pressure levels in various working conditions. Reported data for equivalent sound pres-
sure level for the product has a typical statistical dispersion (standard deviation) of 1 dB (A).
