Sound insulation materials refer to a type of material, component or structure that can block sound transmission or weaken transmittance sound energy.It is characterized by high quality and density, such as steel plates, lead plates, concrete walls, brick walls, etc.The principle of sound insulation follows the law of quality is that the larger the density of the unit dense surface of the sound insulation material, the greater the sound insulation, and the proportional proportion of the surface density and the sound insulation amount.
What are the sound insulation materials
I. Common sound insulation materials 1. Sound sound insulation felt is a better room sound insulation material in the market.It is mainly used to match the gypsum board, for wall sound insulation and ceiling sound insulation, and also applied to the sound insulation and damping vibration reduction of pipelines and machinery.The sound insulation felt is not a felt. It looks completely different in appearance. The felt is light and soft, but the sound insulation felt is thin.The sound insulation felt is refined by the tasteless EPDM rubber and a dozen organic mineral substances in accordance with a certain proportion. The product is black, environmentally friendly, and has a good sound insulation material for low -frequency and high -frequency sounds.The transmission of vibration, the thickness of this material is 1mm, 2mm, and 3mm. After testing by the National Building Materials Bureau, the weight of the barrier is 23DB, 27dB, 30dB, and the material is also very flexible.Construction is very convenient and fireproof sound insulation material.
