Noise Attenuation Performance of a Helmholtz Resonator Array Consist of Several Periodic Parts
The acoustic performance of the ducted Helmholtz resonator (HR) system is analyzed theoretically and numerically. The periodic HR array could provide a wider noise attenuation band due to the coupling of the Bragg reflection and the HR’s resonance. However, the transmission loss achieved by a period...
