Product name: Hard Cotton Sound-Absorbing Cotton
The principle of sound insulation and silencer cotton: it has a large number of pores and bubbles that communicate with the inside and outside. When sound waves are incident into it, it can cause air vibration in the gap. Due to the viscous resistance of air and the friction between air and the pore wall, a considerable part of the sound energy is converted into heat energy. It is consumed. In addition, when the air is compressed adiabatically, heat exchange occurs continuously between the air and the hole wall. Due to the effect of heat conduction, part of the sound energy will also be converted into heat energy.
