Laboratory method of testing to determine the sound power in a duct.

Author(s) : ASHRAE

Type of monograph: Standard/Recommendation

Summary

This standard describes a procedure for the measurement of sound pressure levels in the inlet or outlet ducts of a fan and a method to use these sound pressure levels to calculate the sound power levels radiated by the fan to the duct system. It supersedes ANSI/ASHRAE 68-1986 (see IIR Bulletin, reference 1987-2047) and ANSI/AMCA 330-86.
