Bibliography
Applicable to industrial fans as defined in ISO 5801 and ISO 13349. Determines sound power by using sound intensity measurements on a measurement surface which encloses the sound source. It provides guidelines on the acoustical environment, ambient noise, measurement surface, and number of measurements.
