Today, car manufacturers do not pay due attention to noise and vibration insulation of manufactured cars to reduce the cost of production. Therefore, any car needs additional sound and vibration isolation.
Noise and vibration insulation of a car is a technological process aimed at reducing the degree of penetration of various noises and ambient sounds into the car interior, as well as removing vibrations caused by the metal. To obtain a proper result during the work on noise insulation, it is necessary to correctly position vibration and noise-absorbing materials on the body elements and interior. You need to insulate the following:
Doors: the doors are made of very thin metal and external noise passes through them into the car interior; therefore, the vibration and noise insulation of the doors will help improve the acoustic characteristics of your car.
Ceiling: the ceiling is also made of thin metal, and when driving at high speeds you can hear a rumbling noise from the incoming air stream and the sound of raindrops. If you make noise and vibration insulation of the ceiling, you will protect yourself from this ambient noise.
Floor: vibration and noise insulation of the floor will help you eliminate the noise that gets into the car interior while driving on a bad road, vibration of car suspension, and silencer noise.
Arches: a very high noise comes from the car wheels, which is transmitted through flat surfaces of the body to the passenger compartment. Noise-vibration isolation of wheel arches will help you to avoid excess noise from wheels.
Trunk: by insulating noise of the trunk floor, you will avoid noise at the back of the car.
Hood: the hood of any car is large enough, so all vibration coming from the engine causes unpleasant noise and roar.
