Jiangling County ktv noise damping pad soundproof fireproof material

 Shock absorber factory direct Kun-resistant building materials Co., a ground noise damping pad Application: Ground floor mat acoustic noise damping mainly for KTV, disco, factories, home theater and other strong noise sources. The product is especially suitable for commercial or entertainment center connected to ground noise Liu: 15926397066 13725355629 QQ: 247574381 Taobao soundproofing :( King) (poetic pig) two, ground noise damping pad Product features: for percussion throughout the frequency range with a particularly good sound blocking effect, can most effectively isolate the impact of noise and airborne noise. This foam is a high-density foam, the perforation rate, aperture, etc. are made with a special design, can do noise, vibration, water, mold, suitable for a variety of wet environments. Is a green, life of more than 30 years. Construction is simple, when you install a knife, cut cut, no other tools Third, ground noise insulation principle a cushioning, impact sound insulation through the nano bubbles forming elastic floating floor the entire building structure, cut off the solid audio effects. And improved upper fit ground effect, enhancing the acoustic impedance of the power. Nano-tiny holes through the foam ear-sensitive frequency bands makes acoustic energy generated cavity resonance, weaken the energy of the sound, to reach isolated percussion purposes. 2, the airborne sound insulation foam cavity through the nano resonance effect to change the frequency of the sound transmission, reducing the number of reflections, to cut off the air sound purposes. Fourth, the floor mat acoustic noise damping effect: the laying of the product on the concrete floor 14cm and wiping 4cm thick layer of cement, tiles and insulation effect after following: Rw (C; Ctr) 55 (-1; - 3) dB ISO 717-1 (air sound) Ln, w (Ci) 48 (-1) dB ISO717-2 (percussion) five, ground noise damping pad installation method, smooth, clean surface, before installing the Products by cutting the required size. 2, the foam laid on the floor, the seams are aligned and sealed with tape. 3, to avoid air bubbles between the product and the ground. 4, after Puwan the product, immediately covered with cement and tiles.
