Experimental Study on the Sound Insulation Performance of Periodic Parallel Helmholtz Structure
Helmholtz resonators (HR), which consist of a cavity communicating with the main duct through a neck, have been widely used to effectively attenuate the narrow-band low-frequency noise. In order to improve the sound insulation performance and expand the scope of engineering application
of HR, a kind of periodic parallel HR structure is designed. The structure samples were made by 3D printing technology. The impedance tube experiments has been employed to study the transmission loss (TL) of the periodic parallel HR structure. The experimental results show that the transmission
loss of the periodic parallel HR structure is 10 dB higher than that of the sandwich structure of the same size.
