Ultra-clean Sound Absorption Board
SHENZHOU Ultra Clean Sound absorption board is a versatile sound absorption material specifically designed for different acoustic applications. It has excellent sound absorption properties and acts as a barrier to sound waves (transmission loss); For vibration problems can play the role of damping and de-fluid-structure coupling (vibration isolation).
Product Features
01
Sound Absorption
The design of combination of open-hole structure and composite hole, realizes the effective absorption of air sound in the wide band. The unique combination of physical properties maximizes absorption at critical noise frequencies.
02
Vibration Damping and Decoupling
The relatively high density and high flow resistance provide an effective barrier to sound waves and can replace the multilayer composite foam sound barrier to a certain extent.
03
Sound Barrier Effect
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 vibration isolation pad, it can effectively reduce the structural sound propagation.
