Acoustic attenuation performance of double expansion chamber silencers with interconnecting tube

Z. Ji


A three-dimensional substructure boundary element technique was employed to predict the acoustic attenuation performance of double expansion chamber silencer with inter-connecting tube. The effect of the lengths of inter-connecting tube and expansion chambers, as well as the extensions of inlet and outlet tubes was studied. Overall, significant results were obtained.
