ATTENUATION CHARACTERISTICS OF MUFFLERS WITH GAS RESERVOIR IN LIQUID PIPE SYSTEM -- 1. THE EFFECTS OF AXIAL DIMENSIONS

Theoretical equations which give transmission losses are presented for newly invested mufflers which have a gas reservoir in their expansion chamber so that the normal to the free surfaces agrees with the direction of sound propagation. Transmission losses of many mufflers, which have different axial dimensions, are calculated theoretically and measured experimentally. It is found that this type of mufflers are superior in the low-frequency range to those that have no gas reservoir. The effects of axial dimensions are discussed.
