Noise is one of the strongest irritants for a person that we have to deal with all the time. So, for example, it brings great inconvenience while driving.
Noise can not only interfere with hearing important sounds for the driver, but it also distracts from driving, and just interferes with talking to the passengers sitting in the cabin. However, you can solve the problem of noise very simply: make noise insulation on the car.
Sound insulation can be partial or complete - it all depends on how much time and money you plan to spend on this modification of your car. By isolating the car from noise, you will immediately notice the benefits: for example, the radio will sound much better.
Car soundproofing has several principles.
The first principle is weight. Noise isolation of any object improves with increasing weight, as this reduces the frequency of resonance and vibration. It is on the principle of increasing weight that foam soundproofing materials work.
The second principle of noise insulation is called barrier. Dense rubber or multilayer materials can be barrier. Noise barrier is most effective for low frequency vibration.
When planning to make soundproofing for a car, first decide what kind of noise you want to isolate the interior from. To isolate road noise, you will need to fill the doors with foam and place rubberized mats over the wheels. At the same time, make sure that the drainage holes above the wheels remain free of rubber. Basically, noise isolation is required for the stereo system and the rear doors of the car.
If you need more sound insulation, insulate the ceiling, the floor of the car, and try to isolate the dashboard and the engine to reduce noise from the engine. To do this, you will need to remove the car's interior trim, seats and control panel. In addition to rubber mats and foam insulators, you also need fluids that can penetrate the most difficult-to-reach areas to provide better insulation.
The isolation process is quite laborious. First of all, prepare the surface on which you plan to glue the sound insulator - it should be as clean and grease-free as possible. Cut the material to the exact dimensions of the parts to prevent sound penetration.
