Wave-absorbing cotton
Wave absorbing cotton aka: Eggs crest cotton or cotton, is a widely used in KTV, recording studio, conference room, cinema studio, acoustic test chamber and other places of noise demanding that foam sponge made of polyester , wavy surface, similar to the egg carton loaded, so a lot of people like to call it egg cotton, colors are white, blue, yellow, red, gray, black, etc. The most commonly used is black and gray, because the darker The more dirt.
Conventional wave absorbing cotton size: 1.5mX2m, 1mX2m; thickness 3cm, 3.5cm, 4cm, several more than the thickness of both sides together, such as the thickness of 5cm.
Wave absorbing sponge non-toxic, tasteless, and environmental protection, it is very high quality interior soundproofing material.
Acoustic wave absorbing sponge principle: when an incoming sound wave crest, the gaps between the air will cause vibration; due to air resistance, the air and cause the bore wall portion of the friction sound energy into heat energy is consumed. Further, when the adiabatic compression of air, and continuously between heat exchange with the air hole wall due to heat conduction, but also make part of the sound energy into heat. So as to achieve a sound absorbing effect of the buffer as well, with the aperture size of the sound absorbing effect of the entire batting also has an important relationship between the thickness, if it is too thin sound-absorbing only a small portion of the suction, the other openings discomfort The opening is too large, it will not have sound-absorbing effect is too small it sounds too much power to make life difficult, suitable to work in this area, absorbent cotton can also play some acoustic sound effects, because the sound after absorbing too much time Back to friction with the sound-absorbing cotton, will cushion the original sound of the action for a moment, will reduce the penetration of the original sound, and thus the secondary effects of noise is still there, but the sound insulation cotton had to use a professional ideal .
