What is the principle of noise board?
- Another transmission of sound is the spread of the media. That is, from a medium, through the two media critical contact surface into another medium, this time, the transmission of acoustic energy is the transmission of vibration amplitude. Cross-media propagation, the greater the difference between the density of the two media, the greater the loss of sound energy. In practice, the air is the human normal space, so the greater the density of the material with the density of the material is generally a very high density material (much lower than the air density of the material in addition to vacuum, really not much), that is, Can be regarded as sound insulation material. The higher the density, the better the sound insulation. Such materials made of sheet metal, known as sound insulation boards
