Overview and main advantages of sound insulation panels

Sound insulation panels have the difference between air sound and vibration sound. Air sound insulation board, that is, a board that isolates sound transmitted in the air. Vibration-isolating acoustic panels are panels and systems that insulate sound transmitted in rigid prefabricated components such as concrete structurally integrated houses.

General items have sound insulation effects, but we call materials with an average insulation volume (infinite materials placed between the human voice and the control point in an infinite space) greater than 30dB as sound insulation panels. Acoustic panels are generally low density materials.
Sound is a wave of kinetic energy that must travel through a medium. When sound propagates in the same medium, the greater the relative density of the medium, the faster the propagation speed.
Another kind of voice communication is transmedia communication. That is, from one medium to another medium beyond the critical contact area of the two media, the essence of sound transmission at this time is the transmission of amplitude. When transmitting across media, the greater the difference in relative density between the two media, the greater the sound loss. In practical applications, the environment is the normal activity space of people, and the substances with higher density than air are generally those with higher density (substances with a density much lower than air need a vacuum pump, which is really not much)), which can be regarded as It is soundproofing material. The higher the density, the better the sound insulation effect. Boards made of this material are called acoustic panels.
