Sound Barrier Manufacturers

Flat perforated acoustic panels Features: 1, Screen panel of high-density small holes (in a variety of sheet-like material or a metal plate perforated derived), after the sound into the holes, will be reflected in the inner wall of the structure at random until Most of the acoustic energy is converted into heat energy, in order to achieve sound results. 2, the kind of sound-absorbing panels to absorb high-frequency sound waves mainly fibrous tissue accumulation inner filling a variety of organic or inorganic fibers or open-cell foam and expanded perlite products, the combination of flexible material and a perforated plate use, greatly expanded the scope of sound absorption, increase the absorption coefficient. 3, the porous material allows no reflection of sound energy into sound-absorbing material, not only can efficiently absorb airborne sound, solid sound and vibration can weaken the air chamber air sound caused. Filled within the porous material composed of a variety of sheet-like material composite structure, to improve the sound insulation capacity and reduce the structural weight. 4, flat perforated sound barrier used as a sound absorbing member of the surface layer in road traffic noise barrier, urban rail barrier, high-speed rail and other sound barrier sound barrier project, according to the noise frequency characteristics, customized with different perforation rate, the aperture metal micro-perforated acoustic board.
