What is the noise insulation material of the car?
Materials to light, lightweight is the development of the entire automotive manufacturing sector trend, lightweight materials will not increase the weight of the body after the construction of too much to increase fuel consumption.
Car noise products are divided into four categories: A, shock absorber material B, sound-absorbing material C, sound insulation material D, sealing material, from the lightweight development trend, the ideal car sound insulation material is not shock absorption, sound insulation, sound-absorbing products Of the paste, but should be a product of these kinds of sound insulation principle of the integrated use.
The effective way to block the noise transmission is mainly: sealed, shock, sound insulation, sound absorption. In the shock on the basis of noise, sound absorption and sealing treatment, you can achieve a quiet and comfortable effect. In the whole car for noise reduction process, the use of sound insulation products with their own sound and sound performance will also directly affect the noise reduction effect.
In theory, any kind of material (material) are different degrees of shock absorption, noise, sound absorption ability, even if it is a piece of paper, a piece of cloth.
