Design a New Type of Interfered Muffler Based on Pneumatic Tools

Abstract:

18The traditional interfered muffler has narrow noise elimination frequency range.It has large noise elimination volume only at contracting frequency part. When noise frequency is far lower than contracting frequency, the noise elimination volume will fall rapidly .Designing a composite muffler based on the principle of gas convection, sound wave diffraction, sound reflection and so on. The muffler is mainly used for noise caused by pneumatic tools. Test shows that without affecting the work performance of pneumatic tools, the muffler can be 10-12dB noise reduction, which is worthy applying.
