Why can sound insulation board sound insulation

The sound insulation board is a kind of sound insulation board. Sound insulation rating of buildings and structures. The sound insulation board will not block the sound of various frequencies. The object has a natural resonant frequency. Sound close to the target resonance frequency will deteriorate the sound insulation effect of the sound insulation board. The difference between the sound insulation board is the sound of air and vibration. The sound insulation board is used to cut off the sound in the air. Vibration and sound insulation panels are panels and systems used to prevent sound from being transmitted through rigid components.

At the same time, another voice is transmitted across media. That is, from one medium, through the critical contact of the two media, into the other medium. At this time, the transmission of the acoustic energy is substantially the transmission of the amplitude. The greater the density difference in the two media, the greater the energy loss when transmitted across the media. In fact, air is a space for human activities under normal conditions, so materials with a density different from air are usually high-density materials (the density is many times lower than that of air, except for vacuum, which is really very small), so it can be regarded as a sound insulation material. The higher the sealing, the better the sound insulation. The board made of this material is called sound insulation board.

In addition, the installation effect of the sound insulation board is affected by the installation construction on the one hand, and the sound insulation board material on the other hand. Since the sound insulation board is a high-density material, the greater the density of the sound insulation board, the better the sound insulation effect. In the current decoration construction, the sound insulation board mainly includes: wooden sound insulation board, mineral wool sound insulation board, cloth sound insulation board, polyester sound insulation board, etc. The following brief introduction, the follow-up will be detailed one by one these sound insulation Products!

Although in theory, ordinary items have a certain sound insulation effect, only the average sound insulation capacity above 30dB is called a sound insulation board. Sound insulation panels are usually installed in conference rooms, recording studios, KTV and other special places. In order to avoid the impact on the lives of the surrounding residents, some highway sections are also equipped with sound insulation panels.
