Development of a test facility for making in-duct sound measurements according to Astm E477-1984

Duct silencers must reduce sound levels enough to be noticed by the human ear. By placing the appropriate duct silencer in the air-conditioning duct system, sound levels in rooms where noise is a problem can be significantly reduced. Only through insertion loss measurements can the appropriate silencer be determined for the desired noise reduction; This thesis involves the modification and qualification of the reverberation chamber in the Multi-Function Lab at the University of Nevada, Las Vegas, for the purpose of creating a controlled sound testing environment. It also involves the design and construction of facilities for making insertion loss measurements. The thesis concludes with the testing and analysis of five duct silencers.
