Common materials: Including polyurethane, rubber, EVA foam, etc. These materials have characteristics such as high elasticity and good damping properties, which can effectively absorb vibration energy and block sound. There are also some shock-absorbing and sound-insulating mats made of a mixture of acrylic resin, rubber, and fiber cotton, such as the Huanuobang acrylic composite rubber sound-insulating mat.
Some shock-absorbing and sound-insulating mats have special structures, such as nano-foam structures. They absorb sound energy through small holes and use the cavity resonance effect to change the sound propagation frequency, achieving effective isolation of impact sound and air-borne sound.
