Sound Absorption Panels
Wide band sound absorbing panel is our proprietary product that is able to absorb wide frequency of sound wave. The inventor, Dr. Wang won recognition in 1995 under the Invention Convention Award in the category of Architecture and Industrial Technology.
Wide band sound absorbing panel consists of sound focusing units that are very efficient in preventing noise reflection and diffraction. Its unique patented design has four times larger surface area compared with normal acoustic panel. Hence, it is able to trap a wide frequency of sound wave and the experts named it as the “blackhole of sound”. It has been tested to ASTM C423 and is proven to be the only sound adsorbing panel that can achieves an average NRC (Noise Reduction Coefficient) of more than 110% over a wide band of soundwave from 100-4000 Hz.
Wide band sound absorbing panel can be installed in both indoor and outdoor as it is durable, weather-proof and aesthetically pleasing for any application. It is very useful in many applications such as theatreatte, music studio, railway/MRT tracks, highway/expressway, condenser towel, engine room & etc.
