The surface of the wave sponge is shaped like an egg holder, which acts as a sound insulation. The principle of the wave sponge is to circle the sound wave in the wave crest, so that it weakens and disappears. Therefore, the larger the wave crest, the longer the gyration channel and the better the sound insulation effect.
Sound-absorbing wave sponge, egg cotton, sound-absorbing sponge and sound-insulating sponge are made of polyurethane sponge, which is foamed by complex process and has the functions of sound-silencing, sound-absorbing, sound-insulating and shock-absorbing. Wave shape or pyramid shape on sponge surface has good sound absorption and noise reduction effect. Wave-like materials or pyramid interior is filled with small voids. Porous structure can absorb a large amount of sound energy injected into it, and play a attenuation role. The sound absorption effect is excellent after testing. The absorption coefficient is as high as 0.85, which is a muffler. High Performance Products of Noise Reducing and Shock Absorbing Materials. Decorative design of sound absorption board, sound insulation ceiling has greatly improved the sound absorption performance.
Pyramid sound absorption sponge is made of high density sponge with a density of more than 30 kg. It has beautiful appearance and good acoustic characteristics. Sound waves are reflected back and forth in sponges to absorb sounds at frequencies above 500 Hz, reduce the interference and echo of indoor reflected sound, and improve the purity of sound. Based on this design, the Pyramid Sound Absorbing Sponge enhances the installation function. It provides a minimum joint, which can make the installation more beautiful. At the same time, the shape of the pyramid also provides a little additional diffusion effect.
Opening: Opening structure is to increase its sound absorption capacity and optimize the process of increasing its internal porosity, to ensure the sound absorption coefficient of pyramid sound absorption sponge, so a small amount of pyramid sound absorption sponge can be used in the room to get the expected reverberation time.
Density: The higher the density, the stronger the ability to absorb low frequencies. The high-density structure of pyramid sound-absorbing sponge gives it a very wide absorption band. The absorption frequency of 50 mm thick pyramid sound-absorbing sponge can reach more than 500 Hz.
Wave sponge is used in packaging shock-proof, shock-proof, skid-proof, sound absorption, sound insulation and so on.
