EXPERIMENTAL INVESTIGATION ON ACOUSTIC ATTENUATOR BASED ON PERIODIC HELMHOLTZ RESONATOR WITH EMBEDDED MEMBRANE
Helmholtz resonator (HR) is widely used as an effective silencer in duct noise control applications. The HR reduces noise at its resonant frequency with a narrow attenuation frequency band. To get a wider attenuation frequency band, HR can be arranged periodically with a certain distance. The extens...
