 Principle of sound insulation
Volume (R) dB is an important parameter of the recording studio, to control the volume of the sound can be used to make the sound recording studio to be possible. Combined with the actual environmental noise, the average sound insulation amount is R=60dB, which can only be allowed to project to the surface of the one percent of the transmission. The low noise single value control at 25Db.
Sound insulation method can generally be divided into two categories,
One is active, passive acoustic block; two.
Active block: the object is to use a close sound insulation materials to block the sound, such as brick walls, concrete, damping noise. But to know that sound can be spread on any object (as long as the object is vibrating). Because we have to think of ways to stop the vibration of objects. To prevent the vibration can not be hard, on the contrary with the soft material can be a good effect. The sound insulation of the soft solid is usually better than the solid solid, because it is not easy to vibrate, like a shadow boxing to dissolve the vibration. Damping sound insulation felt is a good material, with a sound insulation felt around the room, there will be a very good effect of noise, in addition, to add a hard material to add a damping pad can contribute to noise.
Passive sound: the way is using sound-absorbing material is placed in a voice only, by a large number of sound absorption, naturally play a sound effect. All the sound-absorbing materials can act as it usually is, polyester fiber sound-absorbing cotton we also call it insulation cotton, the effect will be the best cheap.
We usually have two ways combined, using multi-layer design, like biscuits, a cover layer, a variety of hard, soft, combination of sound-absorbing material. The final sound insulation effect and your material, design, the overall thickness of the.
