How to reduce noise and soundproof the engine noise?

1. The engine noise is loud, and the method of noise reduction is: the noise and vibration generated by the engine operation can be blocked by pasting sound insulation materials on the U-shaped groove, firewall and bottom plate. Engine cover and firewall sound insulation can choose aluminum foil soundproofing and vibration damping plate combined with aluminum foil soundproofing cotton or aluminum foil sound-absorbing cotton, which are all good soundproofing materials.

2. Make a fire barrier wall U-groove in the engine compartment for soundproofing. You need to use fire barrier wall sandwich cotton and damping sound insulation and vibration damping pad. To remove the dashboard in the cockpit for soundproofing, you need to use a damping sound-insulating cushion, damping sound-absorbing cotton and polyester fiber cotton.

3. If you are very concerned about this noise and want to soundproof it, we suggest the following method: install soundproof cotton on the engine cover.This can effectively block some noise. Soundproof cotton can also be installed inside the car door, which can also shield some of the noise in the car.

4. Sound insulation and noise reduction method with loud engine sound: install a soundproof panel on the engine. Installing soundproof panels on car engines is also a very cost-saving method. Although the effect is not very big, it can only withstand the noise from the engine. The wind noise on the road can't be solved.

How to solve the problem that the engine is too noisy?

1. Solution: In this case, replacing better quality fuel can generally reduce the engine noise. The engine is fixed and loose. You should know that the engine is not simply placed in the engine compartment, but is supported and fixed by parts such as claw pads. If those parts are aging and loose, it will lead The engine makes noise when it is working.

2. The loud noise of the car engine can be solved by installing sound-absorbing foam, pasting sound-absorbing cotton, installing door seals, attaching vibration damping plates, changing tires, and regularly maintaining the car on time.

3. Solution: Same as above, check the plastic parts in the engine compartment, and generally fasten or adjust.

How to reduce engine noise and soundproofing

Use soundproofing materials: Installing appropriate soundproofing materials around the engine compartment can effectively reduce engine noise. Installing a soundproof screen: Installing a soundproof screen can effectively suppress noise and reduce the intensity of noise.

The engine is equipped with soundproof panels. Installing soundproof panels on the car engine is also a very cost-effective way. Although the effect is not very great, 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.

The engine is noisy, and the way to reduce noise is: the noise and vibration generated by engine operation can be blocked by pasting sound insulation materials on the U-shaped groove, firewall and bottom plate. LaunchFor the sound insulation of the motive cover and firewall, you can choose aluminum foil soundproofing and vibration damping plate combined with aluminum foil soundproofing cotton or aluminum foil sound-absorbing cotton, which are all good soundproofing materials.

Check whether the soundproofing materials in the key parts are loose. Sound insulation cotton is an essential material for car noise cancellation, but it is much more than good quietness.

If you are very concerned about this kind of noise and want to soundproof it, we suggest the following method: install soundproof cotton on the engine cover. This can effectively block some noise. Soundproof cotton can also be installed inside the car door, which can also shield some of the noise in the car.
