Acoustic tuning their own hands

Before proceeding with the description of how the interior noise insulation is carried out, we would like to note: if your car costs less than $ 50 thousand, then you can not be under the delusion that you will not need this article. Believe me, your car has enough problems with noise inside the cabin, and besides, not a single serial car is processed with noise-absorbing materials so well that you can fully enjoy the high-quality sound of your favorite songs.

At the same time, we are not going to talk about all the "jambs" of noise insulation, especially since each brand of car has its own. Today we will talk only about those problems that exist in absolutely any car and tell you how to do acoustic tuning with your own hands.

What is acoustic tuning and how to deal with noise?

Such tuning of the car can be roughly divided into two stages: carrying out the main noise insulation and preparing the cabin for sound.

1. The main insulation.

It will include the elimination of overtones that arise during the operation of any car, namely:

• noises from a running motor;
• noises from wheel rotation and their friction on the road surface;
• structural vibrations that occur at the time of movement of any car (the reason for their occurrence is poorly fixed metal body elements and plastic interior parts).

So, all these problems exist in every car, so if you want to improve its acoustic characteristics, then be prepared to get rid of all these sounds one by one. And for this you will have to carry out partial or complete damping of the body. In other words, it is necessary to stick in certain places the Shumoff Mix bituminous soundproofing materials, which, due to their unique structure, effectively damp vibrations in different body elements (ShumoFF Mix F is suitable for the same purposes). In this case, it is not so much the area of the processed surface that is important here, but the quality of the "rolling" of the materials.

For example, the most problematic areas in almost all cars are the wheel arches, the floor tunnel (especially if the car is rear-wheel drive) and the bulkhead . Therefore, special attention should be paid to these body parts. And the best effect can be achieved if, in these places, on top of the above-mentioned bitumen-based material, noise-absorbing materials with an open- cell structure Shumoff P4 are glued .

2. Acoustic tuning of the salon.

Here we mean the preparation of the salon for some kind of advanced system. Moreover, if this is not done, then you can generally forget about the high-quality low-frequency component of the sound. And first, let’s define what is most important in car audio? Of course, this is a victory over various "parasitic" and resonant noises and overtones, so it is necessary to treat the volumes in which the speakers will be mounted (most often installed in the door) with all the responsibility.

And here you need to understand that an effective acoustic volume can only be achieved with high-quality noise-insulating materials, for example, such as Shumoff Comfort 3 (glued to the inner surface of the doors).

The next step is to create volume under the rear shelf. But this will only be needed if speakers are also installed in this place.

And now the most important thing is tuning the roof of the cabin with your own hands, because it is she who is considered the most dimensional passive emitter, which can ruin all your previous efforts. Therefore, do not regret damping materials for this part of the cabin, and do not forget to paste over them with noise absorbers from above.

Everything, now you collect the car, turn on the audio system, enjoy the awesome acoustics and remember us.
