Noise emissions in the environment are measured as sound power (L
2000/14/EC. The difference between guaranteed and measured sound power is that the guaranteed sound
power includes dispersion in the measured result and variations between different units of the same product
according to directive 2000/14/EC.

Equivalent sound pressure level, according to EN ISO 19432, is calculated as the time-weighted energy total
for different sound pressure levels in various working conditions. Reported data for equivalent sound pressure
level for the product has a typical statistical dispersion (standard deviation) of 1 dB (A).
