Study on the Monolithic Muffler Acoustic Field Performance of the Train Air-Conditioning

This article take the monolithic muffler which is commonly applied in the train air-conditioning duct as the study objection. Simulates the monolithic muffler acoustic field performance with SYSNOISE. Gets the internal acoustic pressure distribution. Measurements on the test-bed of train air-conditioning duct have done and verify the correctness and rationality of the simulation results. We get the monolithic muffler transmission loss was obtained by simulation. It provides the basis for the muffler performance further study.
