soundblox ACOUSTIC masonry units

SOUNDBLOX® meet CSA standard A165.1-1964, for hollow load-bearing concrete masonry units and can be incorporated wherever ordinary hollow masonry blocks are used. Rugged durability permits the use of SOUNDBLOX® units in walls of industrial plants, gymnasiums, etc. where acoustical treatment is often most advantageously placed. This is usually impractical using soft, non-durable materials. Due to the rear thru-chamber design and knock-outs, the 25/30 cm Type RSC-RF SOUNDBLOX® can be horizontally and vertically reinforced and may be used in situations requiring high load bearing capacity.

SOUNDBLOX® Type RSC-RF series offers an enhanced sound absorption rating (NRC value) of .80 or greater – similar to a typical 25mm acoustical panel. SOUNDBLOX® Masonry Units are part of the building structure so their supplied and installed cost is comparatively less. The 20cm Type RSCF SOUNDBLOX® uses a sequential design with 4 chambers. The 25/30 cm Type RSCF SOUNDBLOX® uses a sequential design with three chambers to increase the NRC value without affecting the structural ability.

Noise Reduction Coefficient (NRC) is calculated by averaging the sound absorption coefficients of a material at four frequencies (250 Hz, 500 Hz, 1000 Hz, and 2000 Hz) as measured in a reverberation room according to ASTM C423 standards.

Measured for a wall constructed of 20cm Type RF Soundblox Units. Using the same method (NCMA-TEK 69B, KAL 369-5-66), ordinary hollow concrete blocks show a STC rating of 46. Soundblox walls have markedly better sound transmission lass than walls constructed of ordinary blocks of the same dimensions.
