The whole carWhere to do sound insulation

1. Door soundproofing: Four-door soundproofing usually adopts a three-layer soundproofing method, the first layer is the inner car soundproofing, the second layer is the outer car soundproofing, and the third layer is generally the interior panel soundproofing cotton treatment. The effect of the soundproofing panel is to strengthen the sheet metal thickness and reduce resonance.

2. The four doors and chassis of the car, as well as the engine, are the most useful places for soundproofing. Car soundproofing can provide you with better noise reduction effect, isolate noise, and also reduce engine noise. The sound insulation effect of cars is related to sound insulation materials, soundproof parts, worker skills and other factors.

3. For car soundproofing, the door, cockpit floor, trunk, rear wing plate, front wing plate, hood, fire barrier wall, U-shaped groove and roof are generally used for soundproofing. Different parts have different functions.

4. The most important thing for the door soundproofing strip is to strengthen the empty seal of the door and door frame, effectively reduce the wind cutting sound of the car driving at high speed, and can also replace the waterproof adhesive strip of old and elastic fatigue, and the most important thing is to improve the airtightness in the year. The front and rear wheel arcs and leaf panels are soundproofed, which is the most common place for chassis noise.

5. In-car floor soundproofing. In-car floor soundproofing is the most complex part of soundproofing modification, and it requires a lot of car disassembly. Therefore, car owners should be mentally prepared before doing this kind of soundproofing.

6. Expand all What should I do if the car's soundproofing effect is not good? After having a car, when you encounter loud noise, the first thing to do is not to complain negatively, but to find out the cause and take the right medicine. Vehicle noise is divided into three types: tire noise, wind noise and resonance.

How to reduce car noise?

Many cars also have soundproof cotton in the engine compartment, which can not only reduce the noise of the engine, but also has other wonderful uses, such as heat insulation and preventing the aging of the cover paint. Choosing to install soundproofing materials, such as soundproofing cotton, soundproofing blankets, etc., can effectively and quickly improve the quietness of the car. Because the cost is not high, it is also the method chosen by many car owners.

The ways to reduce car noise are: replace silent tires and use well-known brands of fully compound oil (which can effectively reduce engine noise) to maintain appropriate speed, drive at a uniform speed, and remove all additional parts on the exterior of the car to soundproof the whole car.

The sealing strip can fill the gaps, closely combine the door and rear trunk lid with the car body, enhance the airtightness of the car, effectively reduce air noise entering the car, and naturally make less noise in the car.The seal also has the effect of blocking dust and heat.

The noise in the vehicle is mainly caused by the three aspects of engine noise, wind noise, and tire noise. Noise reduction should start from these three points: reduce engine noise.

The way to reduce engine noise is to paste sound-absorbing material under the hood. How to reduce wind noise: install seal + door soundproofing. Methods to reduce tire noise: door, door edge, upper part of the wheel arc, wing plate and chassis are pasted with soundproof materials; replace comfortable tires; front and rear wheel covers are pasted with soundproof cotton curves.

How to soundproof the car

1. Install soundproofing cotton. If the sealing of the car is not particularly good, the sealing strip cannot have the effect of sound insulation. You can block the noise by installing soundproofing cotton on the car.In particular, the whole car is equipped with soundproof cotton to remove noise, which has the best effect. Replace the door seal.

2. How to soundproof cars? How to soundproof cars? The most obvious thing about car noise should be engine noise, but it is difficult to avoid. The simplest and most effective way is to install soundproofing cotton, which can isolate most of the noise.

3. The most obvious car noise should be the engine noise, but it is difficult to avoid. The simplest and most effective way is to install soundproof cotton, which can isolate most of the noise. In addition, it is usually necessary to fix the foot glue, etc., which can greatly reduce noise.

The method of car soundproofing. Among the car noise, the most obvious should be the engine noise, but it is difficult to avoid. The simplest and most effective way is to install soundproofing cotton, which can isolate most of the noise.In addition, it is usually necessary to fix the foot glue, etc., which can greatly reduce the noise. Tire noise.

The simplest and most effective way to soundproof cars is to install soundproof cotton. The effect of car soundproofing is related to sound insulation materials, soundproofing parts, staff skills and other factors. Usually, the noise that car owners hear during driving mainly comes from tire noise, wind noise, engine noise, environmental noise, vibration, etc.

Noise can be blocked by adding soundproof cotton to the car. In particular, the whole car is equipped with soundproof cotton to remove noise, which has the best effect. Replace the door seal. If the car's seal loses its original effect, the car can have better sound insulation by replacing the door seal.

The ways to reduce car noise are:Replace the silent tires using well-known brands of fully compound oil (which can effectively reduce engine noise) to maintain appropriate speed, drive at a uniform speed, and remove all the additional parts on the exterior of the car to soundproof the whole car.

Noise reduction method 2: Install the door seal. Function: to deal with external wind noise. The seal can fill the gaps, closely combine the door and rear box cover with the car body, enhance the airtightness of the car, effectively reduce the air noise entering the car, and naturally make less noise in the car. The seal also has the effect of blocking dust and heat.
