Abstract

The effect of geometry shape of the Helmholtz resonator on its resonant frequency and noise attenuation capability is discussed in this paper. The theory of resonant frequency depending on the shape of the vessel of the resonator is verified analytical and numerically using COMSOL for one and two degrees of freedom resonators. The simulation was validated experimentally and has shown very good agreements.  Various shapes of the resonators were compared in arrays. A better understanding of the shape effect is shown through simulations.
