Sewer Pipe Sound Insulation Cotton

The principle of sound insulation cotton

The vibration of the object produces sound → sound waves are transmitted in the air → cotton has multi fiber structure → sound waves are reflected, superimposed and collided by countless fibers when passing through cotton, and sound energy is converted into heat energy → sound intensity is weakened → sound disappears. The transmitted sound energy is attenuated to 3 / 10 ~ 4 / 10 or less of the incident sound energy.

For sound insulation cotton, to weaken the transmitted sound energy and block the transmission of sound, it cannot be as porous, loose and breathable as the sound-absorbing material; on the contrary, its material should be heavy and dense, such as lead plates, steel plates and other materials. The requirement of sound insulation cotton material is that it is dense without pores or gaps; it has a larger weight. Because this kind of sound insulation material is dense, it is difficult to absorb and transmit sound energy and the reflection energy is strong, so its sound absorption performance is poor.
