波浪棉细节特写


吸音原理: Wave sponge sound absorption principle:

It has a large number of internal and external pores and bubbles. When sound waves are incident into it, it can cause air vibration in the gap. Due to the air's viscous resistance and the friction between the air and the pore wall, a considerable part of the sound energy is converted into heat energy and consumed. In addition, when the air is adiabatically compressed, heat exchange occurs between the air and the hole wall. Due to the heat conduction effect, a part of the sound energy is also converted into heat energy.
