Study on Band Gap and Sound Insulation Characteristics of an Adjustable Helmholtz Resonator

To solve the problem of low-frequency noise in the environment, a Helmholtz-type phononic crystal with adjustable cavity structure and labyrinth tubes was designed. The unique design of the labyrinth tube greatly increases the length of the tube, improving low-frequency sound insulation performance,...
