Optimal design of acoustic metamaterials for noise suppression by the frequency division in military equipment

Optimal design of acoustic metamaterials for noise suppression by the frequency division in military equipment

This paper presents a multi-Helmholtz unit series–parallel acoustic metamaterial with a segmented noise control effect designed by taking advantage of the adjustable frequency band of an acoustic metamaterial, aiming to change the main noise spectrum characteristics under different driving condition...
