Description

Construction Road Noise Barrier Fence Roadway Soundproof Sheet

Acoustic barrier for highway is mainly used as a noise reduction of road, highway, viaduct and other noise sources. It refers to a kind of barrier set at the edge of road or railway in order to reduce the impact of vehicles' noise on residents nearby.A kind of facility is established between sound sources and recipients to let sound transmisson have a remarkable additional reduction, thus alleviating the bad influence of noise on areas where recipients are in; this kind of facility is Acoustic Barrier For Highway.

The function of sound barrier is to prevent the transmission of direct sound, isolate the transmitted sound, and make the reflected sound have enough attenuation. Therefore, the attenuation of sound barrier is designed by using the principle of sound reflection. Sound waves (noise) for transmission on the way, if meet barriers (sound barriers), reflection will happen, so within the scope of a certain distance behind obstacles to form the "shadow", the area size depends on the size of the voice (frequency), see from this, the noise attenuation of noise barrier is closely related with the center frequency value.
Due to the high frequency sound shadow area is large, short wavelength, so the most easy to be blocked, the second is the intermediate frequency sound, the sound barrier formed behind the sound in the shadow of the low frequency sound, due to the long wavelength, circling around the barrier, it is easiest to diffraction in the past, so the surrounding environment will produce certain effect, so the noise barrier on its low-frequency noise sound insulation effect is poorer, proved by actual measurement: The sound barrier has no obvious attenuation for low-frequency sound with a frequency below 250Hz, but it has a better attenuation effect for medium and high-frequency sound.
