Short Description: Acoustic sponge is a Sound-absorbing cotton,it is the result of the formation of a unique special handling equipment side convex shape of the wave through the complex process of foam generation after silencer, sound-absorbing, reducing vibration of polyurethane foam materials. Product filled the gap and fine structure allowed the opening half acoustic energy can play a greater absorption of the incident sound attenuation effect, reducing indoor acoustic echo reflected sound interference and maintain the purity of the sound; the sound is acoustic noise reduction material high-performance products.
Place of origin: China,Sell to worldwide.

Uniquely shaped peaks absorbing sponge, filled with small internal voids wavy material, porous structure can absorb a lot of acoustic energy incident on the play acoustic attenuation. Used in acoustic noise in the high frequency absorption capacity is very strong, but also can be used for acoustic treatment, and require a higher playback room, such as the control room, mixing room, listening room, piano room, home theater, acoustics lab, music studio, audition room, surveying room, KTV room, star hotels and buildings silencer muffler factory construction project, silencer generators, air conditioners, automobiles (heavy machinery) industry and other industries and places. Crest absorbing sponge also often used in precision instruments, electronic equipment packaging as packaging pad, can be a good cushion vibrations, protection equipment, fire-retardant properties, but also to more secure instruments. Wave absorbing sponge (eggs cotton) is the use of polyurethane sponge material. After the formation of special treatment equipment side convex shape of the wave through the complex process of foaming silencer, sound-absorbing, sound insulation, shock absorption sponge materials. Its interior is full of tiny gaps and semi-open cell structure can absorb a lot of incoming acoustic energy to play acoustic attenuation, reducing internal reflection sound interference and response, enhance the purity of the sound; noise absorbing material is high-performance products. Cotton acoustic wave principle: Having a large number of pores and bubbles within and outside the Unicom, when the sound wave is incident thereto, can cause vibrations in the air gap due to air viscous drag, friction with the hole wall of air, so that a considerable part of the sound energy into heat energy is consumed. In addition, when the adiabatic compression of the air, the air continue to occur between the heat exchange with the hole wall, due to heat conduction, but also make part of the sound energy into heat energy. Wave cotton Application: Control room, mixing room, listening room, piano room, home theater, acoustics lab, music studio, audition room, surveying room, KTV room, star hotels and buildings silencer muffler factory construction project, generators silencer , air conditioners, automobiles (heavy machinery) industry and other industries and places.
Pyramid acoustic sponge
pyramid-acoustic-sponge absorbing cotton
Specifications: 500 * 500 * 80MM Color: blue, pink, white, black, yellow Pyramid sound-absorbing sponge absorbing cotton newest pyramid: It is made of a high density of more than 30 # density foam, good acoustic properties, sound waves reflected back and forth through the landscaping in the sponge to absorb low frequency sound than 500HZ, reducing indoor reflection sound interference and response improve the purity of sound. Its most important feature: four pyramid shape also provides a diffusion effect, it makes you sound more dynamic. 1. opening: open cell structure in order to increase its sound absorption capacity and optimized to increase the porosity of its internal processes to ensure the sound absorption coefficient of the pyramid sound-absorbing sponge; so the use of a small amount of the pyramid sound-absorbing sponge in the room, you can get expected in the mix snooze time. 2. Density: the higher the density, the stronger the ability to absorb low frequency. High-density structure of the pyramid sound-absorbing sponge, it has a very broad absorption band, pyramid absorbing sponge absorbing frequencies can reach more than 500HZ, thus ensuring that the room acoustic treatment, there is a flat absorption curve; then even if you use the many also heard a dry sound, rather than a take off of the tweeter’s muffled. Application principle: adjust the sound field inside the chamber and the reverberation, the sound melodious. Home decorating interior walls, is widely used in recording studios, recording studios, audio-visual room, audio-visual room, KTV, soundproof room, conference room, studio, studios, theaters and other occasions: Uses Installation: the glue evenly coated on the back of each sound-absorbing cotton, 80% to be the glue dry sponge tile up, little can beat the level. Common Glue: all-purpose adhesive water, foam rubber, resin glue. Ordinary hardware store which you can buy. With relatively strong double-sided adhesive sticky, posted on cotton or wall, pressed flat to press.

Working Principle on “Acoustic sponge”
Principle: Impact eggs cotton absorption effect is mainly due to the reason the product thickness, product density and the inside and outside air flow resistance and so on. Than the material on both sides of the air pressure and air flow rate per unit thickness of the barrier is air flow. Air flow resistance is the most important factor affecting egg sound absorption properties of cotton. Flow resistance is too small, indicating that the material is sparse, easily through the air vibration, acoustic performance degradation; flow resistance is too large, indicating that the material dense, difficult to incoming air vibration, acoustic performance also dropped. Eggs cotton has many pores and bubbles inside and outside of China Unicom, when acoustic waves incident to 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 is consumption, coupled with uneven wave cotton egg shape, so that the rest of the sound waves repeatedly bump refraction decreases. In addition, when the adiabatic compression of the air, the air continue to occur between the heat exchange with the hole wall, due to heat conduction, but also make part of the sound energy into heat energy. Eggs absorbing cotton, non-toxic, tasteless, environmental health, is ideal for indoor acoustic audio reflective material, widely used in recording studios, recording studios, audio-visual rooms, rehearsal rooms, auditorium, drum room, KTV, Tone Room, a language lab , studio, audition room acoustics lab, conference room, studio, theaters and other places of the interior, as well as room silencers, generator noise, speakers and other places and equipment.
Eggs cotton variety of colors, can be used with different colors, due to the different needs of customers can choose Normal or flame retardant products themselves. For a large number, the product color, size, thickness can be customized according to the requirements.
Pyramid absorbing sponge is made with a density of more than 30 # high density polyurethane foam, with beautiful appearance and good acoustic properties; by sound waves reflected back and forth within the sponge to absorb low frequency sound 500HZ above, to reduce interference of the reflected sound indoor and response, enhance the purity of sound.
Its most important feature: with beautiful appearance and good acoustic properties, based on this design, the pyramid sound-absorbing cotton enhanced installation features, it provides a minimum of seams, which allows to install more beautiful; pyramid shape while also provides a little extra diffusion effect, it makes you sound more dynamic.
1. opening: open cell structure in order to increase its sound absorption capacity and optimized to increase the porosity of its internal processes to ensure the sound absorption coefficient of the pyramid sound-absorbing sponge; so the use of a small amount of the pyramid sound-absorbing sponge can be expected in the room reverberation time.
2. Density: the higher the density, the stronger the ability to absorb low frequency. High-density structure of the pyramid sound-absorbing sponge, it has a very broad absorption band, 50mm thick pyramid sound-absorbing sponge absorbing frequencies above 500HZ can reach.
3. Uses: Widely used in interior decoration studio, recording studio, audio-visual room, audio-visual room, KTV, soundproof room, conference room, studio, studios, theaters and other occasions.
4. Install: Brush glue (all-purpose adhesive glue or resin, etc.) on the back of sound-absorbing sponge, until the glue to dry after seven or eight small force pushing on the wall to steady.
