Eggs sound insulation cotton

Sound-absorbing cotton, sound insulation cotton sound-absorbing materials insulation material colors: black, white, blue,
gray, pink, yellow City: Length 2M X width 1.5MX or thickness 5CM 3CM or 10CM (note that this is two combined thickness
measurement method ) Fei eggs sound insulation cotton aesthetically pleasing appearance and good acoustic properties, its
greatest feature is: because of its uneven surface, it provides a bit more porous diffusion of design, it makes you more
of a voice Seoul vitality. This product is made of polyester sponge material processing, environmental protection,
natural, healthy, and can not be in direct contact with human skin allergy. By the Company with unique equipment and
special transmission characteristics of conventional processing technology into the side of the pyramid-shaped surface.
After blowing through the complex from the noise, noise, sound-absorbing, vibration reduction as one of the sponge
material. Its products are full of fine micro air voids and semi-open-cell structure allowed a greater amount of energy
absorption of sound waves incident to cushion the effect of sound attenuation to reduce sound waves emitted indoors return
coefficient, mainly to eliminate echo played a major role. Gas to maintain the purity of sound, reducing interference echo
of high-performance products for noise reduction materials. Over principle: The main factors affecting the sound-absorbing
cotton sound absorption effect is the product of the thickness, density, and inside and outside air flow resistance and
the like. Than the material on both sides of the air pressure and air flow resistance per unit thickness of the air
stream. Filter air flow resistance is the most important factor sponge sound absorption performance impact. Sparse
explanatory material flow resistance is too small, easily passing through the radiant air vibration, acoustic performance
degradation. Description material flow resistance is too dense and difficult to pass the air vibration, acoustic
performance also declined. So when selecting the sound-absorbing cotton, sound insulation cotton in a considerable
knowledge or consulting professionals. Sponge inside and outside China Unicom has many pores goods and bubbles, when the
acoustic wave to the incident in which, it can cause vibrations in the air gap due to the viscous resistance of air, the
air and the hole wall friction so that a large part of the sound energy into heat energy to convey, and from there the
quilt consumption to achieve the effect of sound absorption and sound insulation. She coupled with uneven wavy shape
sponge let the rest of the sound wave is gradually reduced in unevenness repeated refraction. Also when the air adiabatic
compression continue to occur between the air and the walls of the hole limit heat exchange, due to the directed action it
will also make part of the sound energy into heat energy, so as to achieve sound-absorbing effect. Sound-absorbing effect
with cotton as well as the entire thickness of the size of the openings has an important public relations, too thin even
make a sound absorbing only a small part of the suction. Also opening discomfort and opened large is too large will not
sound-absorbing effect is too small to make life difficult sounds too much resistance. Sound-absorbing cotton Secretary to
absorbing some of the sound effects can also be achieved, because the sound after noise cotton sound-absorbing cotton of
time will create friction with the original sound wave will buffer some. It will reduce the original sound penetration.
Thus noise is still an auxiliary effect. But had to use sound professional expertise cotton sound effect is better! If the
purpose of: the sponge non-toxic, tasteless, environmental protection, is ideal for indoor acoustic audio sound-absorbing
material shot back. Widely used in the studio, recording studio, drum room, audio-visual room, audio-visual room, the
measured sound room, studio, KTV, language lab, acoustic test lab, conference room, studio, piano room, movie theater,
interior decoration and other occasions sound-absorbing. And a generator room silencer, silencers and other equipment..
