    Road sound barrier

    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.
    product material:
    Outer plate: 1.0-2.0mm galvanized steel plate, stainless steel plate;
    Sound absorbing panel: 0.4-2.0mm galvanized steel plate, stainless steel plate, hole diameter φ3, punching rate>25%;
    Sound absorbing material: 24-80kg/m3 centrifugal glass wool board, stable performance, good sound absorption performance, non-combustible, wide application range;
    Protective glass cloth: alkali-free water-repellent glass fiber cloth, which protects sound-absorbing materials;
