Description
Product advantages
       Egg sound-absorbing cotton
       

   Egg cotton is also known as wave cotton and crest cotton. It is a kind of sound-absorbing cotton. Egg cotton is a kind of sponge that has been specially treated by equipment to form a convex and concave wavy shape. Its interior is full of small voids and semi-opened structures, which can absorb a large amount of incoming sound wave energy and attenuate sound waves, reducing the interference and noise of indoor reflected sound. Reverberation, improve the purity of sound, is a high-performance product of sound-absorbing and noise-reducing materials.

    It has a large number of internal and external pores and air bubbles. When the sound wave is incident into it, it can cause the air in the gap to vibrate; due to the viscous resistance of the air and the friction between the air and the hole wall, a considerable part of the sound energy is converted into heat energy and consumed. In addition, when the air is compressed adiabatically, heat exchange occurs continuously between the air and the hole wall. Due to heat conduction, part of the sound energy is also converted into heat energy. In order to achieve the effect of sound buffering and sound absorption, the sound absorption effect has an important relationship with the size of the opening and the thickness of the entire cotton. If it is too thin, even if it can absorb sound, it can only absorb a small part, and the opening is uncomfortable. If the opening is too large, it will have no sound-absorbing effect. If it is too small, it will help too much sound. In this regard, the workmanship is appropriate. The friction with the sound-absorbing cotton will buffer the movement of the original sound and reduce the penetrating power of the original sound, so it still has an auxiliary effect on sound insulation, but it is better to use professional sound insulation cotton for sound insulation.
