What is the difference between acoustic wall panels and sound-absorbing board? How to choose?

In the decoration need to use different sound insulation materials, acoustic wall panels is one of them, there is another is the sound-absorbing board. Most people don't know the difference between the two and what each does. Today, let's solve the difference between acoustic wall panels and sound-absorbing board.

1. The material difference between sound absorbing board and acoustic wall panels

Sound-absorbing board is generally porous material, groove wood sound-absorbing board is generally front slot, back hole; And the hole wood sound-absorbing board is full of holes, soft package sound-absorbing board inside is also a lot of tiny gaps, it can be said that sound absorbing material is basically "pore" material. And acoustic wall panels is not the same, it must be high-density material, sound is not easy to penetrate. acoustic wall panels is made of high-density materials, the appearance is generally not processed, usually several boards or sound insulation felt composite.

If you dig deeper, you'll see that they're on opposite sides. The sound-absorbing board is an extension of a line (sound wave), and the acoustic wall panels is a broken line of a line (sound wave). Sound absorbing board is used to extend the space of sound waves, must have a gap. The functions of the sound-absorbing board are: noise reduction, echo elimination, so that the sound quality is clearer, suitable for places with high acoustic requirements; And acoustic wall panels is used to limit the space of sound waves, must be tight. The room with the sound-absorbing board has good sound quality, but no sound insulation; The room with acoustic wall panels, if the room is small, the sound quality inside is not very good, but the outside is unable to hear any movement inside Oh.

2. sound-absorbing board and acoustic wall panels performance difference

In terms of performance, the sound-absorbing board has the functions of moisture-proof, mildew proof, fire proof and non-combustible, sound insulation and heat preservation, environmental protection, insect prevention and corrosion resistance. Acoustic wall panels sound insulation and noise reduction, water resistance, UV resistance, light safety, dustproof durable, can resist 10~12 typhoon. But they also have in common, environmental protection and non-combustible, in line with environmental testing standards, are A1 level non-combustible substrate.

If speaking normally, acoustic wall panels will certainly be better, when the house is decorated, the use of acoustic wall panels is equivalent to isolation from the foundation, can effectively in the fundamental sound insulation. If you use sound absorbing cotton, that is the general wall is not sound insulation, so it will be from the outside with sound absorbing cotton to sound insulation.
