Primacoustic Broadway Scatter Blocks 12" X 12" (305mm X 305mm)

  • Used to control flutter echo and reverberant field
  • The ultimate in Soft Diffusion™
  • Easy to install on practically any surface
  • Wide range of great looking patterns and colors

Broadway Scatter Blocks present an ‘easy-to-install' solution for acoustic treatment where you want to control sound, but do not want to eliminate natural ambiance.

Made from high density 6 pound per cubic foot high density glass wool, Scatter Blocks are designed to be randomly spaced on large wall surfaces to create an effect we call Soft Diffusion—an affordable alternative to full scale quadratic diffusion. By leaving reflective spaces in between the panels, some energy is absorbed while some is left to reflect back into the room. This helps control flutter echo and reduces standing waves while retaining a sense of ‘air' or space in the room.

This makes the Scatter Blocks an excellent choice for live-end, dead-end designs in studios, controlling chatter echo in home theatres and presents a cost effective solution for larger spaces such as dance studios, fitness centers and classrooms that need to be tamed in effort to reduce the reverberant field and improve intelligibility.

Broadway Scatter Blocks come in1" thick panels, in grey, black or beige.

Mounting

Mounting Scatter Blocks is easy and quickly accomplished using Primacoustic Surface Impalers. Most installations only require one impaler per panel. For areas with higher traffic, two
impalers may be used. For extra security, add a dab of construction adhesive on the impalers, to secure the panel in place. This is recommended in class rooms or public places.

*Notice: In our opinion, the short form sound absorption coefficient does not provide reliable data regarding the performance of a particular panel versus the problem frequency. This data is provided for comparison sake only. Please view the full frequency chart below to ensure that the panel you are considering will actually attenuate the frequencies you are attempting to absorb.

Test data provided by Bodycote Materials Testing Inc. This method, designated as ASTM E 84-05, "Standard Method of Test for Surface Burning Characteristics of Building Materials", is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire-hazard or fire-risk assessment under actual fire condition.
