The principle of sound insulation board

 

    Felt is an effective soundproofing material, suitable for controlling the spread of noise and making spaces quieter. So what is the principle?

     First of all, we understand that sound waves propagate in the form of waves, and porous materials mostly absorb sound waves to isolate them.

    Sound insulation felt has high density, strong internal damping performance and is not prone to vibration. When attached to the veneer, it can also prevent the vibration of the veneer, thereby making the noise lose the possibility of vibration transmission.

    Sound insulation felt is made of  PVC + polymer metal powder and various additives. Polymer metal powder is one of the main raw materials of sound insulation felt. It is made by rolling and ultimately becomes a new type of sound insulation material. It is also ultra-thin and can achieve the best sound insulation effect when paired with sound-absorbing cotton.
