[Board] basic instructions noise damping noise problem we must first deal with a clear distinction between the mode of transmission of noise, sound propagation is divided into two ways: one is the acoustic structure, hit the floor with a hard object such as the noise generated by the structure is sound transmission; another species are airborne sound, such as outdoor vehicles to and from the voices of the room. Noise different modes of transmission, and its treatment in different ways. Sound damping structure would need to be treated at the source of the sound, and the air you need to use a high-density acoustic soundproofing material. Noise damping plate is sandwiched between two layers of high-density plastic polymer composite made noise, high sound volume density can average up to 37 decibels of noise in the middle, there are very good rubber damping effect, both noise damping soundproof panels, other single damping performance insulation materials or cushioning materials can not have. [Board] product features noise damping CD Ke noise damping plate for high-density materials to glass magnesium board for the materials, intermediate adding insulation materials made of composite production. Specifications Weight 50kg / block, 1440 * 1220 * 16mm / 18mm / 20mm fire resistance to glass magnesium board for raw materials, fire GB8624-1997A level, sound insulation 37DB, as an insulation materials, environmental protection E1 grade, 100% asbestos-free , fire smoke-free, and create green and healthy living space. [Board] damping noise deadening effect of the product advantages of good and bad is difficult to see that, so in the choice of high-quality noise damping plate first look at the density is high enough, quality high density damping soundproof panels smooth surface white sheet, in the middle of the black soundproofing glue, made from three-layer composite, 2440 * 1220 * 16mm weight 50KG a soundproof panels, hand you can feel its high hardness, and poor sound insulation board due to the low density, the weight is not enough , surface roughness, hardness is low, the amount of noise is certainly below standard, and in transportation and installation process is also easy to damage. Also, choose a reputable manufacturers to buy soundproofing material is also critical for the noise, the material is the most important, good material can reduce a lot of unnecessary trouble, but to achieve the best sound effects, I founded many years, Focus soundproofing materials research and development, production, on the quality of the material more secure.
