Experiment Analysis on Noise of the Minibus Exhaust Muffler

On the basis of analysis and research on an automobile exhaust noise, the theory and test combination method was adopted to improve the muffler, and then the acoustics performance of muffler was validated by doing some experiments with the engine. On different speeds of the engine, the inserting loss and spectrum characteristic under several muffler methods were studied. Finally the best muffler method was confirmed, and the purpose of reserving was achieved.
