With the continuous improvement of people's living standards, they are more and more sensitive to the surrounding environment. Nowadays, noise nuisance has become a normal phenomenon. How to control the generation of noise in your own home or noise source? At this time, we need to use the sound-absorbing board. So the sound-absorbing board and sound insulation wall are different to a certain extent. Please look down on the differences.

The difference between sound absorption panels and sound insulation walls is that the sound absorption of materials focuses on the size of the reflected sound energy on the side of the sound source, and the principle is to reduce the reflected sound energy. The sound insulation wall focuses on the size of the transmitted sound energy on the other side of the incident sound source, and the principle is to reduce the transmitted sound energy. Generally, the attenuation and absorption of sound absorption material to incident sound energy is only a few tenths. Therefore, the sound absorption coefficient can be expressed by decimal; while the sound insulation material can make the transmitted sound energy attenuate to 10-3 ~ 10-4 or less of the incident sound energy. For the convenience of expression, the sound insulation loss is indicated by the measurement method of decibels.

The difference between the two materials in terms of raw materials is that the reflection of the sound absorption material to the incident sound energy is very small, which means that the sound energy is easy to enter and pass through the material. It can be imagined that the raw material of this material should be porous, loose and breathable, which is a typical porous sound-absorbing material, which is usually made of fibrous, granular or foamed materials to form a porous structure; Its structural characteristics are: there are many interconnected micropores from the surface to the inside, that is to say, it has certain air permeability. When the sound wave is incident on the surface of porous material, it will cause air vibration in the micropores. Due to friction resistance, viscous resistance of air and heat conduction effect, an appropriate part of sound energy will be converted into heat energy, so as to achieve sound absorption effect.
