Sound insulation felt is the thicker the better?

 Soundproof walls to build its intention is to choose the appropriate sound insulation, sound insulation, sound insulation and vibration felt felt production data, with construction science is very important, but consumers in the purchase of insulation materials when not only to common sense thinking, some general insulation board for the traveling sound effect and talent. To simply add data weight and thickness to travel noise rate, this method is of course useful, but there are many defects in storage:
1: when the noise volume relatively moving, the noise power is low, according to the physical rules based panel density doubled on the sound insulation theory can only add 6 dB, while the sound insulation wall density increased four times, the highest amount added 12 db;
2: wall thickness add relatively space of more use to build the indoor area of relative reduction; (sound deadening felt felt, Cheng Jing)
3: the wall is thicker, the raw material to produce wallboard price rise, economic investment increased, add, and relatively sound harvest is very small.
So, to consider the plan noise factors, the balance of the two resident arrived in sound insulation, sound insulation, sound insulation mat letter static Cheng felt professional sound information is the principle of new sound insulation products, the sound insulation effect is to add weight and thickness to the end, and the relative market with the same thickness with the components of the sound insulation of goods he felt, static, sound deadening felt not only the noise power is high, the effect is good, and arrived at the same thickness than other functions with more excellent heavy goods.
