The simplest and most effective car soundproofing method

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.

Is it enough to make four doors or the whole car soundproofing

1. If you want to do it for soundproofing, it is recommended to do the whole car soundproofing. If it is for the economy, do the four-wheel soundproofing. If you want to be economical, if you only want to install the stereo, you should make it four doors.

2. Making four doors can effectively reduce wind noise and resonance: the four-door soundproofing should first disassemble the door, remove the interior panel on the inside of the door, and then start the double-layer soundproofing and noise reduction construction of the four doors, and assemble and restore it after the construction is completed. The position of the four-wheel wing plate can effectively reduce the noise caused by the friction between the tires and the road surface and the resonance of the sheet metal when the car is running.

3. We need to be clear that car soundproofing is divided into partial soundproofing and whole car soundproofing. Whole car soundproofing is said to be the best effect and the most expensive in car soundproofing. However, it is not recommended that all cars should be soundproofed, because it is very expensive to do so.

4. I believe that many car owners will choose four doors for soundproofing when doing car soundproofing modification, because four doors are the most basic soundproofing of the whole car, and the price is relatively cheap. However, some car owners have questions, is it necessary to soundproof the four doors of the car? Because many people say that the effect is not obvious after sorting out.

Tricks to reduce car noise

1. Install a soundproof panel on the engine. Installing soundproof panels on the car engine is also a kind of non-Although the cost-saving method is not very effective, it can only resist the noise transmitted by the engine. And the wind noise on the road can't be solved. The whole body of the car is equipped with soundproof cotton.

2. The second method is to replace the door seal. Some cars are originally very quiet, but more noise is generated after a long time of use. In this case, the seal loses its original effect. At this time, the door seal can be replaced to restore the sound insulation effect of the car.

3. The ways to reduce car noise are: replace silent tires and use well-known brands of all-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.

Car Sound insulation function and principle

Soundproofing: Automobile soundproofing engineering can effectively eliminate and block engine noise, vibration, resonance of body doors, friction sound generated by air resistance when driving, etc., giving you a quiet driving space and greatly improving the comfort of driving.

Paste a fireproof and soundproof blanket on the engine cover to absorb the engine rotation noise. Strengthen the rigidity under pillars A, B and C, reinforce the rear seat side panel, and improve the rigidity of the body structure, which has the effect of reducing noise.

Sound insulation is mainly carried out on the vibration damping plate and sound-absorbing cotton. The function of the vibration damping plate is shockproof, and the effect of the sound-absorbing cotton is sound absorption. The sound-absorbing cotton combination of the single-layer vibration damping plate is a sound insulation. In order to improve the sound insulation effect, it is necessary to increase the number of layers of vibration damping plate and sound-absorbing cotton.

Automotive soundproofing improves the defects of the speaker installation environment through vibration damping materials and sealing automobile sheet metal, restores the sound pressure and sound quality effect of automobiles, reduces the noise transmitted by automobile sheet metal structure and improves driving comfort through vibration damping materials and soundproofing materials.

Isolate the noise outside the car, eliminate travel fatigue and eliminate the harm of noise to the human body, protect your physical and mental health, and take care of your family. Absorb and reduce the noise in the car caused by oscillation, improve the ride comfort and the quality of the car environment, and increase the driving safety and stability of the vehicle.Heat insulation.

What is the sound insulation of the whole car

1. Door soundproofing: The four-door soundproofing usually adopts three-layer soundproofing method, the first layer is the lumen 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 board is to strengthen the thickness of the sheet metal and reduce the 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. The most important thing is to strengthen the empty seal of the door and door frame, and effectively reduce the carThe wind-cutting sound of high-speed driving can also replace the old and elastic waterproof adhesive strips, most importantly, to make the airtightness better in the annual use. The front and rear wheel arcs and leaf panels are soundproofed, which is the most common place for chassis noise.
