Environmental noise pollution seriously affects the health of people, and noise transmission can be effectively blocked by using materials or through structural design. Generally, the greater the areal density of the material, the better the sound insulation. However, the pursuit of high areal densities has led to increased economic costs. The honeycomb structure is widely applied to important fields of buildings, transportation, aerospace and the like due to the unique advantages of light weight, energy absorption, vibration reduction, energy storage, electromagnetic shielding, high specific stiffness, high specific strength, designable performance and the like. When the sound wave propagates to the walls of the honeycomb plate, the sound wave vibrates back and forth in each small honeycomb, and large sound energy loss is caused. Meanwhile, for sound waves with specific frequency, the diffraction phenomenon of the sound waves can be caused, so that the energy of the sound waves is diffused, and a good noise reduction effect is achieved. Typically, honeycomb structures are often combined with porous sound absorbing materials, microperforated panels, and the like into composite structures to improve the overall acoustic properties of the structure.
