🚗Best materials for car soundproofing for 2020

In order for the car to deliver maximum pleasure to its new owner, everything must be perfect. This is possible provided that the purchase is aesthetically pleasing, the movement is comfortable and there is no noise. If during a trip in the cabin you can clearly hear the sounds made by plastic parts and the main components of the car, then there is a reason to sound the alarm. Owners of elite brands are deprived of such problems. Inexpensive brands have sacrificed the quality of sound insulation to reduce cost and thus shifted this problem onto the shoulders of future drivers. The result is a salon filled with all sorts of sounds.

In this case, it is necessary to think about the independent implementation of comprehensive measures to improve the parameter. Online stores offer a wide range of different materials that can cope with the task. Each of them has its own nuances and features of use. Regardless of how exactly the work will be performed (by a qualified specialist or independently), it is necessary to understand the type of material.

Expected Result

Before proceeding with the task, it is necessary to study the problem step by step and develop measures to eliminate it. Soundproofing is a costly process, and I would not like to find out after it that what I wanted was not achieved. First you need to understand the nature of the problem. Allocate:

• Structural noise. The reason for the appearance lies in strong vibrations of the power unit, mechanism, transmission and chassis. In this case, the suspension elements that transmit to the bodies and the floor become the conductors.
• External. Sources - engine and transmission, noise enters the vehicle interior by air. In addition, tires, door seals and exhaust are the causes. Much depends on the quality of elaboration of the above nodes.

To achieve the desired silence, manufacturers offer a wide range of products in various directions. The choice of material determines the source of greatest discomfort.

Is there any benefit

1. The safety of movement increases. Excessive sound that affects a person for a long time negatively affects the nervous system. A driver who is in a cabin for a long time, filled with various kinds of extraneous noises (creaking of the body and plastic, hum from passing cars, etc.) is distracted from the road and can get into a traffic accident. An experienced owner, who has traveled more than a dozen thousand kilometers, will not hear the resulting breakdown (knocking shock absorber struts, worn out pads). Delays in resolving the problem will worsen the situation.
2. Comfort. Reducing noise has a positive effect on the well-being of those in the cabin. The driver is enjoying the ride. Carrying out work will allow you to get a full range of positive emotions from the installed audio system and subwoofer.
3. Other benefits. The materials used protect the body from corrosion. Such a car will last longer without carrying out body repair work.In cold winter, the material will keep the cabin warm, and in the summer it will keep the air conditioner cool.

What happens

When choosing a material, it is necessary to take into account their variety and the tasks performed. It is possible to achieve maximum results by combining several different directions.

• Sound absorbers.

The most popular type of insulation. They reduce the noise level from the road and vehicle elements. The material absorbs various sounds. Premium coating dampens up to 95% of external noise. Many motorists make the mistake of using it alone. The maximum effect is only possible when combining several types of material. The basis can be natural or synthetic fiber-structured products, gas-filled plastic materials. Silencers of the first type are used by the vehicle manufacturer. It is generally accepted that they have the greatest efficiency, but due to the absorption of moisture they quickly become unusable. Plastic-based material is devoid of such problems.

• Vibration dampers.

When driving, most of the body elements create vibration and noise. The main task of the vibration damper is to damp the vibration amplitude of mechanical units. Sound arises in elements as a result of hitting a surface and then converting it into vibration. To repay them, use a viscous material based on bitumen, and mastic, covered with foil on top. The elastic part rubs against the foil, and due to this, mechanical energy is converted into heat. The adhesive base provides secure attachment to the body. The main characteristic that should be paid attention to is the mechanical modulus of elasticity. In addition, the mechanical loss factor is important. Its magnitude affects weight, size and absorption efficiency.

• Antiskrip.

Dense matter with a sticky composition below. With its help, the minimum gaps in the joints of the ducts are closed. Cases of replacement with soft sound insulators and even ordinary foam rubber, window insulation, plasticine and other similar solutions are not uncommon. High-quality antiskrip is durable, resistant to abrasion, tolerates negative environmental influences and is convenient to use. The latter quality is especially important, since it is used in hard-to-reach places.

• Liquid insulation.

It is mainly used in places where the use of sheet metal is impossible. As a rule, outside, this is due to the negative impact of the environment. There are two large groups of products: aerosol and oil. To apply the latter, use a brush or a spatula. This group is resistant to temperature fluctuations, strong chemical and physical influences.

Do all parts need to be processed

1. Hood. Under it is the main source of all problems, which can significantly spoil the experience of the trip for passengers and the driver. When carrying out work, it must be remembered that it is impossible to completely eliminate the motor noise. The main task is to reduce its level as much as possible and insulate it when cold weather sets in. When choosing an insulator for the hood, special attention must be paid to weight. Otherwise, in a short time, the shock absorbers will become unusable. An important factor is the absence or presence of a noise isolator installed at the factory. In the absence, preference is given to insulators with a thickness of at least 15 mm.
2. Doors. The element with the largest area, the main source of noise. Made of thin metal and low insulation. They are practically not an obstacle to sound. The maximum possible area inside is covered with a noise isolator. Elements are treated with antiscrip to eliminate any kind of sounds.
3. Roof. The purpose of the work is to save the owner from knocking on it in the rain and to eliminate buzz when driving at high speeds. Use a lightweight insulator to avoid shifting the center of gravity. After installation, the headliner should return to its original position without any difficulty.
4. Floor. Suspension vibrations, stones hitting the bottom, this and many other things cause noise.It is recommended to use two layers of a thin vibration damper for this.
5. The trunk. Eliminates sounds coming from the rear of the car (hum when accelerating, hitting rocks, branches, movement of a transported load, etc.) and improves acoustics. The surface is covered first with a vibration isolator and then with an antiskrip.
6. Wheel arches. Not deservedly deprived of attention by many motorists. When driving, they transmit vibrations from the wheels to the entire body. To carry out the work, it is necessary to remove the stationary wheel arches and, after a comprehensive cleaning of dirt, install a vibration damper and treat it with anti-gravel.

How to choose

To achieve the most effective result, it is necessary to choose the right material. For this, a number of factors are taken into account:

• Specific gravity. Vibration damping is achieved through the flexibility and construction of the fibers. High efficiency is not possible if the purchased material is too light. It is generally accepted that the thickness of the reinforced aluminum vibration isolator is at least 1 mm. An increase in this parameter allows increasing efficiency, but at the same time, installation and acquisition costs will increase.
• Mechanical loss factor (LF). Its performance ranges from 10 to 50%. The higher the value, the better. Flexibility. Affects the density and quality of adhesion to the surface.
• Life time. To determine it, you need to study the warranty and all available information from more experienced motorists.
• Resistance to mechanical stress. High-quality sound insulation retains its shape and quality during its entire service life. This is due to the fact that in the places where it is mounted, mechanical deformation is almost impossible.
• Thickness. Determined by the type and place of use.
• Mastic. If it is of poor quality, problems will arise during the rolling of the insulation layer. It will squeeze out. In addition, it does not adhere well and flows out of the sheet at high temperatures.
• Adhesion. The amount of effort required to apply for high-quality adhesion to the treated surface. The recommended value is 5 6 Newtons per square centimeter. Many unscrupulous manufacturers in the instructions indicate a value several times higher than it. As a rule, this is a standard marketing ploy.
• Foil. Its thickness should be such that it is impossible to tear it with your hands. Otherwise, there will be problems during rolling.
• Ease of installation. It's about how specific the tools are needed to carry out the work. It depends on whether a self-installation is possible.
