The difference between sound insulation board and sound absorption board

1.The difference between sound insulation board and sound absorption board

In our company, a very common situation, many customers in the selection of products, the sound insulation board and sound absorption board mixed together, it can be seen that they do not understand what is sound insulation and what is sound absorption, the two are different, there is a big difference between sound absorption is not equal to sound insulation, the same reason, sound insulation board is also different from sound absorption board.

2.Principle and function of sound insulation board and sound absorption board

Following a brief description, the difference and function between the sound insulation board and the sound absorption board: the sound insulation board and the sound absorption board are two different concepts, the sound insulation board material is dense, heavy, and the sound absorption board material is porous and light. It is suitable for family residences, Hotel rooms, leisure clubs, volume version KTV and other sound fields which need to reduce noise. It can be used for upgrading the sound insulation of inter-structure walls, original walls and ceiling.

The principle of sound insulation board is that when the sound insulation board starts to vibrate under the impact of sound wave, the polymer material in the middle of the board will undergo continuous compressive stress and shear stress under the action of shear stress, which effectively converts the mechanical energy of sound wave into heat energy consumption and dissipates, thus significantly improving the sound insulation effect of the sound insulation board. The main performance of sound insulation board material is sound insulation, and the sound absorption rate is low. The main performance of sound absorption board material is sound absorption, but the sound insulation rate is low. It is suitable for the interior wall decoration of public buildings such as cinema, concert hall, gymnasium, conference hall, lecture hall, multi-function hall, film and television hall, recording room, etc. to improve the sound quality and improve the voice clarity. Sound absorption board can effectively improve the environmental sound quality, fullness, clarity and stereo sense.
