Sound insulation of doors: inexpensive and efficient

Even if you only occasionally sit behind the wheel of a car, the issue of comfort in the cabin can not be left out. It has already been proved that the noise insulation of doors and the interior of the car as a whole has a beneficial effect on the health of the driver: fatigue is reduced, and attention is increased . The noise level does not just have to fit into the norms. And the comfort zone automatically implies at least relative silence. How to turn a car salon into a comfortable and cozy space?

Where does the noise come from and how to remove it?

The work of all the components of the car is somehow accompanied not only by noise, but also by vibration, which can cause resonance of all surfaces to which vibrations are transmitted. So there is additional noise, which can be amplified because of the errors of streamlining.

The initial actions aimed at reducing the noise level in the cabin should concern technical methods. A carefully adjusted engine, complete serviceability of the car, proper installation of the audio system - all this reduces and partially eliminates various noises even before the work. Sound insulation of doors significantly improves the smoothness of opening and closing, also increases the thermal insulation, which is important when working a heater or air conditioner in the cabin. You can order an appropriate upgrade at a maintenance station, but there is an opportunity to manage on your own.

Effective sound insulation of doors with your own hands

To bring the car doors into the right condition you need to stock up on special materials. Vibroplastic and sound absorber, as well as special glue and means for preliminary preparation of surfaces will be required. The noise insulation of the doors begins with the removal of the inner skin. Take advantage of the case and put in order the mechanisms hidden in the body of the door, if necessary. All dirt is eliminated with rags impregnated with white spirit: you wash dust, dirt and degrease the surface.

Vibrodempfer (vibroplast) is a material that absorbs and damps vibration, which is the cause of noise. It should be noted that in places of sizing the ability of a material to absorb vibration is somewhat reduced, but this is normal.

Vibroplastic covers the outer layer of the door shell from the inside, at the same time, care should be taken to avoid accidentally opening the drainage and ventilation holes. The inner skin is also pasted with a vibroplastic. After that, all surfaces are glued with a silencer, and the inner skin is put in place.

How much does the noise insulation of doors cost?

Depending on the high cost of materials and the chosen method - alone or on SRT - the cost will be from three to ten thousand rubles. In this case, you must take into account the starting characteristics of your machine. If incidentally requires a small repair, strengthening the handles and glass lifts, the price may be higher than you expected. However, independent noise isolation of car doors is possible only if you are confident in your own abilities, because it is not enough to dismantle and glue the doors - you need to collect them correctly.
