Why does noise do not mean sound absorption? How to use good sound insulation, sound absorption material to handle the hall? Ask the master enlighten me!
Second, to prevent the sound of vibration transmission: This plate requires a higher density of the unit surface, that is, the higher the density of the unit surface noise better, which is why the thick wall than the thin wall sound insulation better reason. Usually have fiber cement board and other products. Stone also has a good sound insulation, medium and thick steel plate has a good sound insulation effect.
First, silence: As the name implies, is to reduce the intensity of the sound source, can play this role is usually a porous material, generally common are cotton products. The most effective is the gradient of sound-absorbing cotton, the raw material is made of polyester fiber, but the density is gradient, what it means, that is, side is relatively soft, one side is hard, from soft to hard, soft side of the installation towards the source.
Simply put, the sound is to eliminate the sound outside the room, silence is to eliminate the noise inside the room. Depends on what you need in the end of the hall. Is too noisy outside or room sound is not good.
