Sound insulation screen:
The sound barrier is placed between the sound source and the receiver by using a baffle or a wall to block the sound from directly radiating to the receiver. The main function is to prevent the transmission of the direct sound, to isolate the transmitted sound, and to make the diffraction sound sufficient. attenuation.
The sound barrier is a barrier or partial barrier that obviously interferes with the propagation of sound waves. It can block the propagation of sound and form a sound shadow zone. The noise reduction effect increases with the increase of the path difference. A sufficiently high and long sound barrier can reduce noise by 5-18dB(A) at the acceptance point in the shadow area.
