What is the soundproofing principle of acoustic panels?

Acoustic panels are devices that reduce the transmission of noise by using the properties of the material to force the noise to reflect, scatter and absorb. 

Acoustic panels are usually made of sound-absorbing materials such as foam, fabrics, polyester fibres, etc. These materials have a high sound absorption coefficient and are able to absorb noise. These materials have a high sound absorption coefficient and reduce the transmission of noise by converting the noise energy into heat or other forms of energy loss. 

When installing acoustic panels, the size, shape and density of the panels need to be taken into account and additional sound insulation materials, such as acoustic tape or acoustic membranes, are often required to ensure that the sound insulation effect is maximised.

1、Reflection:The material on the surface of the sound insulation board, such as metal or glass, can reflect the noise back to the source and reduce the noise spread to other areas.

2、Diffusion:the concave-convex or porous surface of the sound insulation board can make the noise scatter at different angles, thus dispersing the energy of the noise.

3、Absorption:the sound-absorbing material inside the sound insulation panel can absorb the noise energy and convert it into heat or other forms of energy, thus reducing the spread of noise.

Acoustic panels are widely used in construction, transport, industrial equipment and other fields, can effectively reduce the impact of noise on human health and working environment.
