The sound insulation principle of acoustic louvers is mainly realized through sound deadening and sound absorption. Specifically:
1、Muffling principle: soundproof louvers are composed of a series of louvers, which are connected with springs between the blades to form a kind of muffler. When the sound enters the muffler louvers, it will produce friction and interference between the blades, thus reducing the intensity of the noise.
2、Sound-absorbing principle: At the same time, the gap between the blades can also play a role in sound absorption, further reducing noise. In addition, soundproof louvers also have the advantages of simple structure, easy installation, remarkable noise reduction effect, long service life and wide range of application. In the industrial noise reduction project, soundproof louvers can be widely used in a variety of mechanical equipment produced by the reduction of Pinji, such as machine tools, stamping equipment, engines, exhaust systems and so on.

Product details description
Acoustic barriers are mainly used outdoors, and are designed to block the direct sound between the sound source and the receiver by inserting a facility between the sound source and the receiver, so that there is a significant additional attenuation of the sound wave propagation, thus attenuating the noise impact in a certain area where the receiver is located. YH-acoustics™ noise barriers are composite noise barriers that combine sound absorption with sound insulation.The combination of louvered panels and sound-absorbing cotton greatly improves sound insulation effect.
