Automotive articles — Soundproofing

Even luxury cars do not have the best indicators of noise insulation, so car owners decide to correct the situation on their own. The success of the procedure is largely determined by the selected materials. The question of how to choose noise isolation occurs even in those who do not first encounter it, because the technology does not stand still and the range grows every day.

The material is divided into the following types:

Sound absorber. It is necessary to minimize external noise, which is about 60% of the total. At this stage, several types of material are used. Accent is the main element that provides thermal insulation and sound reflection. Bitoplast — helps to get rid of the creaking, has a special structure. Isolon: according to its design characteristics is very similar to the accent.

Sound-proof: differ with a face-opener and a structure with closed cells. The main task of such materials is to retain heat and improve the tightness.

Vibration — reduce the degree of vibration in the car interior. One of the main differences of such materials is the viscoelasticity, as a rule, bitumen or rubber is used.

Interlining materials — elimination of squeaking when metal elements come into contact.

The choice of noise insulation is largely determined by your desire and capabilities. So, if you spend most of your time on the road, then it is recommended to use a comprehensive approach, and if not, you can only use directional noise insulation, for example, to eliminate squeaks or vibrations.

When choosing the right material, consider the following nuances:

The quality of the mastic should be high, otherwise it will not touch the surface well, and even at high temperatures it will drain.

The foil layer should not be too thin, otherwise there is a risk of tearing it during installation.

For vibration isolation it is of fundamental importance that the weight of the material is small.

Soundproof material must have high waterproof qualities.

Soundproofing The hood is made in order to protect the motor from freezing in winter: take into account that you need a lightweight material, so as not to weight the hood cover. To get rid of external noise, the procedure is carried out for doors: the sound quality of the music will be much higher. Noise insulation of the roof and ceiling is done to reduce noise during precipitation.
