Laboratory Methods of Sound Testing of Fans Using Sound Intensity
This standard establishes a method of determining the octave band sound power levels of a fan. The method is reproducible when all requirements of the method are met. In this standard, sound power levels are determined using sound intensity measurements on a measurement surface that encloses the sound source. Guidelines are provided on suitable test environment acoustical characteristics, the measurement surface, and the number of intensity measurements.
