AUTOMOTIVE INSULATION & NOISE CONTROL
Sound insulation is a package of measures intended to reduce the level of noise penetrating the car from the outside. So how does the noise penetrate in the car? The noise in the car ensues from the resonance of metal products that are transmitted from the engine, driveline, wheels during their work. A vehicle consists of large parts that produce noise driven by vibrations, such as:
Bonnet (Is exposed to high temperature, as well as vibration from a running engine)
Roof (Transmits to the passenger compartment noise of headwind)
Platform (Transmits noise and vibrations from a running driveline and road noise)
Wheel arches (Transmit noise and vibrations from the wheels)
It is impossible to completely get rid of such noise, but with the help of Allmat soundproofing materials, it can be reduced to a minimum. The long-term experience of Allmat has made it possible to achieve the maximum mechanical loss factor, which is 0,29 unit
How does the sound insulation work?
The main operation principle is CLD (Constrained Layer Damping). Allmat sound insulation sheets consist of a high-tech polymer layer and aluminum foil that absorb most of the vibration and do not allow noise to get into the car.
It is necessary to learn the difference between vehicle sound insulation and other types of sound-absorbing products. Household soundproofing material, such as roofing tape or repair tape, could not only provoke rust on the vehicle body and bad smells, but also a vehicle fire. Such materials are not intended to work in aggressive conditions, such as: sudden changes in humidity, constant vibrations and high temperatures.
Sound insulation Allmat is a choice of professionals in many countries around the world. Through the use of high-tech polymer layer and high-quality aluminum foil, you will get comfort and silence in the passenger compartment.
Besides the use of soundproofing materials is one of the most important steps in preparing a vehicle for an installation of an audio system. Each manufacturer is trying to provide only minimum requirements for the acoustic comfort of the vehicle, so when installing an audio system in an unprepared vehicle, you couldn’t achieve the required sound quality.
The installation process may seem complicated to you, but you can install sound insulation by yourself without experiencing any specific problems.
The main aim of the installation of sound insulation is to increase comfort for drivers and passengers. It will help to:
- Reduce vibrations from the engine and road noise, getting into the vehicle
- Remove creaking and crackling in the passenger compartment, which emit plastic trim parts
- Improve the sound of your audio system
- Warm the passenger compartment
