Abstract

The Helmholtz resonator is widely used as an effective way to reduce noise around the resonance frequency. But the resonator is a single degree of freedom and has a narrow resonance frequency band which determined by its geometry. This paper used three-dimensional finite element method to calculate the acoustic characteristics of different arrangement of the Helmholtz resonant. It is can be found that 2 Helmholtz resonators connected in parallel, the narrow-band not be changed and the performance of muffler is enhanced. As for the 2 degrees of freedom Helmholtz resonator has two resonance frequencies, and the narrow-band has been broaden. From the simulation, the performance of muffler has no significant change with distance change, but the effect of two Helmholtz resonators has been changed by the angle between the two Helmholtz resonators.
