What is the type of noise board?
Such as the use of sound-absorbing cotton, sound-absorbing panels and other materials, the use of continuous analysis of the sound of the way to achieve the weakening of the transmission of sound, while changing the scope of sound transmission.
According to the location of noise classification, roughly divided into indoor noise and outdoor sound insulation two categories. Such as indoor noise, including: walls, tiles, ceilings, and other features that require sound insulation, the underground building noise is also the input of indoor noise parts; and outdoor sound insulation main projects are open-air wall noise and other outdoor noise The
According to the classification of civil engineering categories, can be divided into building noise and structural noise two.
Constructed from noise is a kind of soundproofing that uses a certain form or method to construct sound waves from noise or combine to block sound propagation.
According to the method of noise classification, can be divided into composite noise and structure from the sound and so on. Composite sound insulation refers to the use of a variety of sound insulation materials for a new sound insulation practices. In the use of different sound insulation sound insulation materials, the use of their own characteristics, in the noise in the composite use, to play the advantages of their respective sound insulation materials to improve the overall performance of noise, so that "rigid and flexible, multi-channel sound insulation, comprehensive protection "The effect.
