Melamine Foam Solves Your Car Noise Problem

CHENGDU, China - March 13, 2024 - PRLog -- Sources of noise in cars

First of all, we need to understand the source of noise in the car. Noise in the car usually comes from the following aspects:

Engine Noise: This is the most obvious of the car noises, mainly due to engine squeaking.

Tire Noise (https://www.sinoyqx.com/products/automobile-solutions/tires-with-acoustic-foam-inside/): This is air noise caused by the movement of air in the gaps between the tire treads. However, if the tire noise is too loud, it may be that the tire is aging or the depth of the tread groove is too shallow. It can be replaced if necessary.

Wind noise: This includes the noise caused by the pressure change caused by the separation of airflow around the car body, which is caused by the air sucked in from the gaps in the cab and car body and interacts with the airflow around the car body.

Chassis noise: This is usually due to a problem with the shock absorbers, and the entire car will make a loud noise when passing over uneven roads.

How to solve the noise inside the car?

1. Paste melamine foam under the engine cover to reduce engine noise. SINOYQX melamine resin foam is compounded with non-woven fiber, aluminum foil, PVC and other materials, and is widely used in automobile engine heat insulation and sound insulation covers, firewall, vanity mirror visor (melamine resin foam (https://www.sinoyqx.com/products/melamine-foam/) has excellent resistance to UV radiation), large vehicle body noise reduction and heat insulation filling, etc.

2. Install sound-absorbing cotton materials on the trunk, the bottom of the trunk and the wheel eyebrows on both sides of the trunk.

3. Install sealing strips in the car door to reduce noise inside the car.

4. Replace car tires, because new tires have good elasticity and have better performance in terms of noise and comfort. However, if the tire noise is too loud, it may be that the tire is aging or the tread groove depth is too shallow.

5. Pay attention to check whether the screws of body parts are loose. Generally, the problem can be solved by tightening the screws or replacing parts.

6. Clean the door lining, and install melamine sound-absorbing materials, mute materials, vibration-absorbing materials, etc. on the lining board.

7. Tire noise belongs to structure noise, and its main cause is vibration. In response to the high standards of quietness and safety required by new energy vehicles, SINOYQX developed special melamine foam for new energy tire noise reduction, which can reduce tire noise from 9 dB to 15 dB.

8. Check the air conditioning system: Various components of the air conditioning system, such as fans, compressors, etc., can be inspected and damaged components cleaned or replaced.
