Bibliography
Relates with the determination of the acoustic performance of industrial fans. Also 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.
