【Abstract】 Theoretical study of mufflers used in water pipeline was carried out through characteristic method,and the transfer loss of several mufflers was calculated. The contrast between the results of characteristic method and experiment showed that this method can be used to calculate the transfer loss of mufflers. The result also show that muffler can be used to centrol fluid_born noise in water piping system.更多还原
