SHENZHOU Polyurethane rubber vibration damping cushion by environmental protection rubber particles,rubber foam, Cork and other materials,combined with polyurethane glue adhesive autoclaved from the environmental protection of sound insulation material paving. The special structure of the polyurethane rubber sound insulation cushion can insulate the impact noise between floors, and reduce the vibration transmission in the building structure.
Characteristic
01
Impact Sound Isolation
02
Shock Absorption Effect
03
Aero-acoustic Isolation
Good viscoelastic characteristics can effectively reduce or eliminate the resonance of the metal sheet structure (such as sound insulation cover, pipe wall, etc.), so as to reduce the radiation noise of the structure. When used as a shock absorbing pad, it can effectively reduce the structural sound propagation.
Through the elasticity of nano-foam, the whole floor is formed as a floating structure, and the solid sound transmission effect is cut off. The anastomosis effect of the upper floor is improved, and the acoustic impedance is enhanced. Through the tiny holes of the nano-foam, the sound energy of the sensitive frequency band of the human ear can produce cavity resonance, weaken the energy of the sound, and achieve the purpose of isolating the impact sound.
Through the nano foam cavity resonance effect to change the frequency of sound propagation, it will reduce the number of reflections, in order to achieve the purpose of isolating air sound.
