Estimating the noise reduction effect of the Helmholtz resonator using a two-degree-of-freedom mass-spring-damping model
To reduce noise, Helmholtz resonators are widely used in internal-combustion engine intake systems, in the rocket engine's combustion chambers and building wall materials. As a bass-reflex-type loudspeaker, Helmholtz resonators may also be used to increase the sound pressure level. The adva...
