Product Description

Metal shutter sound barrier is a device inserted between the sound source and the receiver to make the sound wave propagation have a significant additional attenuation, thereby reducing the noise impact in a certain area where the receiver is located. Such a facility is called sound barrier fence. In the process of sound wave propagation, three phenomena, reflection, transmission and diffraction, occur when the noise sound barrier is encountered. Usually we think that the barrier can prevent the transmission of direct sound and make the transmitted sound attenuate sufficiently, and the influence of transmitted sound can be neglected. Therefore, the sound insulation effect of the sound barrier can generally be expressed by noise reduction scale, which reflects the above two kinds of sound shielding capabilities of the sound barrier construction. A noise barrier is inserted between the sound source and the receiving point. The barrier is infinitely long. Sound waves can only be diffracted from above the barrier, and then a sound shadow area is formed, just as light is shaded by an object. In this sound and film area, people can feel that the noise is obviously reduced, that is, the noise reduction effect of the industrial park sound barrier shortens the construction time and reduces the cost of the project.

The noise barrier fence panel, which is between 1 m and 5 m in height, covers the effective area with an average noise reduction of 10-15 dB (A) (125 Hz-40 000 Hz, 1/3 octave), up to 20 dB (A). Generally speaking, the higher the road sound barriers, or the farther away from the louver upright sound barrier, the better the noise reduction effect.
