SOUNDBLOX RSC & SOUNDBLOX RSC-RF
SPECIFICATIONS  

SOUNDBLOX Type RSC
SOUNDBLOX derive their excellent sound absorption from a unique cavity-slot resonator construction. The cavities are closed at the top, and the slots allow the cavities to function as damped (Helmholtz) resonators - an excellent sound absorption tool at low frequencies. The slots of the RSR, RSC and Q Type units are funnel shaped for superior acoustical performance.

The amount of sound absorbed by properly installed SOUNDBLOX is increased dramatically when units incorporating a metal septum (membrane or divider) and fibrous filler in the cavity are specified. Together with funnel-shaped slots, these units provide higher levels of sound absorption across a wider range of frequencies. In addition to sound absorption, SOUNDBLOX walls have a superior sound transmission loss (STC) performance rating when compared to walls of ordinary, hollow concrete blocks made of similar aggregates.

 

 

 

SOUNDBLOX Type RSC/RF
The Type RSC/RFSOUNDBLOX units provide the sound absorption of our Type RSC units by incorporating closed cavities and fillers with metal septa with two additional straight-through cavities for reinforcng or other use. This allows specification of this unit in applications requiring vertical reinforcing, thermal insulation or accommodations for vertical conduits and/or pipes. Available in 8", 10" and 12" thicknesses.
