The comparison between acoustic board and soundproof board

Before the market emerged a large number of various types of sound absorbing board and sound insulation board, but caused more people's doubts, whether to use sound absorbing board or use sound insulation board better.
The following is a comparison between the sound-absorbing board and the sound-proof board:
The function of sound-absorbing board is to absorb natural noise, life noise and industrial noise through sound-absorbing materials for the sound absorption and noise reduction. Sound insulation board is used to limit the acoustic space, must be strict. Dismount sound absorption board space, good sound quality, but not sound insulation; sound insulation board space, small inside the house sound quality is not very good, but outside can not hear any movement inside.
In the comparison of sound absorbing board and sound insulation board is, should be compared from all aspects, including sound absorption coefficient, sound insulation coefficient, fire prevention performance, environmental protection performance, in the raw material comparison of ordinary base material, environmental protection base material and fire prevention base material, at the same time to understand its principle and function.
Sound-absorbing board installation is generally to want environmental protection and fire prevention, have large decibel sound is not suitable to choose sound-absorbing board.
Sound insulation board is suitable for large decibel sound near, or its own belongs to the sound source, without clear sound of places and buildings are suitable for sound insulation board. Some special circumstances, such as conference room, cinema, theater and so on entertainment places, both to sound insulation and sound absorption places, need to use two kinds of material composite way to achieve.
Actual sound-absorbing board and sound insulation board selection, but also should consult the relevant professional acoustic consultant. Finally, it should be noted that whether the choice of sound absorption board or sound insulation board, the installation is completed after the need to maintain, so as to extend its actual service life.
