Abstract

Commercial airplane air conditioning system noise is one of the primary passenger cabin noise sources. Silencers are extensively used to quiet airplane air conditioning system noise. Silencer acoustics performance is influenced by the inner form and acoustic damping materials in silencer. The noise attenuation effect is verified by simulated analysis and laboratory experiment. Acoustics experiment results on airplane show that passenger cabin noise reduces more than 5 dB with silencer.
