Muffler Used on Civil Aircraft Air Condition Noise Reduction
Abstract— Civil aircraft air condition noise is one of the main resource of cabin noise. Muffler is widely used to reduce aircraft air condition noise. Muffler acoustics performance is related to the interior structure and sound absorption material in muffler. The noise reduction effect is varied by simulation and laboratory test. Acoustics test result on aircraft with muffler indicate that cabin noise drop more than 6 dB with muffler
