ABC's of SOUNDBLOX | sound absorption coefficients | specifications

A. ABSORPTION [NRC .85]
SOUNDBLOX wall as a sound ABSORBER. Sound energy is absorbed rather than reflected, dramatically reducing "reverberation times"
   
B. BARRIER [STC 56]
SOUNDBLOX partition walls, in an enclosed space, act a BARRIER, greatly reducing sound energy from being transmitted to an adjacent room, increasing speech privacy. When used as an outside, free standing barrier, the high STC assured maximum performance.

C. COMPOSITE: An "Absorptive Barrier"
In addition to sound absorption, SOUNDBLOX walls have superior sound transmission loss characteristics when compared to ordinary hollow core CMU's made of similar aggregates. The combination of an "Absorptive Barrier" makes SOUNDBLOX ideal for applications such as Highway and Railway Noise Barriers and Transformer Noise Screens.
