BYD Song max's car door needs sound insulation. First, the inner layer of the door panel should be sound-insulated. Sticking the cut damping plate on the outermost steel plate of the door can effectively suppress the noise generated by the vibration of the door panel and the outer sheet metal, making the door thicker. First of all, we should do a good job in sound insulation of door panels. The refitted technician made double-layer sound insulation treatment for the front and rear four doors with anti-vibration devices, which effectively reduced the introduction of wind noise and road noise, as well as the * * * vibration of the doors, formed a sealed box of the doors, and provided a good acoustic environment for the speakers.
