Sound insulation material Sound insulation material refers to a material that can weaken or block the propagation of sound waves. The sound insulation performance is expressed by the decibel difference between the incident sound energy and the transmitted sound energy of the material. The greater the difference, the better the sound insulation performance.
For a building space, if its enclosure structure vibrates under the action of external sound field or is directly impacted by objects, it will radiate acoustic energy to the building space, so the sound outside the space will be transmitted to the building space through the enclosure structure, which is called "sound transmission". The incoming sound energy is always less than the external sound or impact energy, so the enclosure structure isolates a part of the sound energy acting on it, which is called "sound insulation". Sound transmission and sound insulation are just a phenomenon, and a pair of complementary concepts are obtained from two different angles.
