Sound insulation boardIs the role of sound insulation plate. Buildings and structures have sound insulation ratings. Acoustic panels do not block all frequencies of sound. An object has a natural resonance frequency. Sound close to the resonance frequency of the object will significantly reduce the sound insulation effect of the sound insulation board. Sound insulation board has the difference between air sound insulation and vibration sound. The air sound insulation board is a board that blocks sound transmitted in the air. Vibration and sound insulation panels are panels and systems that prevent sound from propagating in rigid components.

  At the same time, another sound transmission is cross-media transmission. That is, from one medium, through the critical contact surface of two media, and into another medium. At this time, the transmission of sound energy is essentially the transmission of vibration amplitude. The greater the density difference between the two media, the greater the acoustic energy loss when propagating across the medium. In practical applications, air is the space for human activities under normal circumstances, so materials with different densities from air are generally high-density materials (materials with much lower densities than air, except for vacuum, are really not much), That is, it can be regarded as a sound insulation material. The higher the density, the better the sound insulation effect. Panels made of such materials are called acoustic panels.

  In addition, the installation effect of the sound insulation board will be affected by the installation construction on the one hand, and the material of the sound insulation board on the other hand. Because the sound insulation board is a high-density material, the higher the density of the sound insulation board, the better the sound insulation effect. In the current decoration construction, the common sound insulation board mainly includes: wood sound insulation board, mineral wool sound insulation board, fabric sound insulation board and polyester fiber sound insulation board. The following is a brief introduction, the follow-up will introduce these sound insulation products in detail one by one!

  Although in theory the general object has a certain sound insulation effect, but only the average sound insulation capacity in30dBThe above plate can be called sound insulation board. Under normal circumstances, the sound insulation board is usually installed in the conference room, recording studio,KTVand other special places. In some highway sections, sound insulation panels have also been installed to avoid affecting the lives of surrounding residents.
