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.

Soundblox® Acoustic Masonry Units: The Future of Soundproofing Masonry

In the realm of architectural advancements, Soundblox® Acoustic Masonry Units stand out as a testament to innovation. These units are not only designed for structural integrity but also prioritize acoustic excellence.

Key Features of Soundblox® Acoustic Masonry Units:

  • CSA Standard Compliant: Meeting the CSA standard A16511964 for hollow load-bearing concrete masonry units, Soundblox® ensures both safety and performance.

  • Enhanced Acoustics: With an impressive NRC value of 80 or greater, Soundblox® units offer sound absorption similar to typical 25mm acoustical panels.

  • Structural Strength: Being part of the building structure, Soundblox® units are both cost-effective and durable, making them ideal for various applications.

Soundblox® Acoustic Masonry Units are more than just masonry blocks; they represent a harmonious blend of structural design and acoustic engineering. Opt for a solution that delivers on both sound control and architectural integrity.

  • Walls

    These can be used as stand-alone exterior walls, or as part of a larger building.

  • Education Sector: Gymnasiums, Auditoriums, Hallways, Corridors, Etc.

    Recreation Sector: Pools, Fitness Studios, Curling Rinks, Etc.

    Entertainment Sector: Theatres, Performance Spaces, Community Halls, Etc.

    Industrial Sector: Transformer Stations, Noise Enclosures, etc.

  • In construction specifications, the content is organized into divisions that detail requirements for different construction components. Acoustic masonry, given its structural and sound control nature, would typically not be found under Division 9, which is dedicated to "Finishes."

    Instead, acoustic masonry would likely be located under Division 4, titled "Masonry." Within Division 4, you would find various sections related to brick, block, stone, and other masonry materials. Acoustic masonry would be situated under a subsection dedicated to specialized masonry products or systems. Depending on the specific format or version of the specification in use, acoustic masonry might be categorized under a title like "04 72 00 - Acoustic Masonry Units" or a similar designation.

    Within this section or subsection, you would encounter detailed specifications for acoustic masonry, including material descriptions, installation procedures, performance criteria, and other relevant specifics.

    If you're working with a particular set of construction specifications or a unique format, it's always recommended to consult the table of contents or index to locate the exact section where acoustic masonry is detailed.

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.
