    Cavity resonant absorbing materialIt is a material used to reduce noise and reflected waves, and its principle is to use cavity resonance to absorb noise waves. Cavity resonance absorbing materials are usually composed of multi-layer structures, with a layer of air or foam sandwiched between each layer to form a cavity. These cavities can absorb sound waves and convert them into micro vibrations or thermal energy, thereby reducing the reflection and propagation of noise.

Characteristics of cavity resonant absorbing materials:

1. Good absorption effect: Hollow resonant absorbing materials can effectively absorb sound waves, reducing the reflection and propagation of noise.
   

   
   

2. Adjustable resonant frequency: According to different application requirements, the resonant frequency of the material can be adjusted by designing and adjusting parameters such as cavity size, thickness, and spacing to achieve different absorption effects.
   

   
   

3. Good durability: The cavity resonant absorbing material is made of high-strength and wear-resistant materials, which have good durability and compressive performance and can be used for a long time.
   

   
   

4. Easy installation: The cavity resonant absorbing material is easy to install and can be directly pasted or installed on buildings, equipment, and other parts.
