Industrial fans - Determination of fan sound power levels under standardized laboratory conditions - Part 1 : general overview

In addition, it may be used to determine the acoustic performance of fans combined with an ancillary device such as a roof cowl or damper or, where the fan is fitted with a silencer, the sound power resulting from the fan and silencer combination.
