PRIME7™ BIFRACTAL

BROADBAND HARDWOOD DIFFUSER-ABSORBER

Overview

Prime7™ BiFractal is an attractive broadband acoustical product that diffuses sound uniformly from all angles of incidence. This product is a quadratic residue design derived from mathematical number theory sequences for phase grate technology, then precisely manufactured to provide what can only be described as a diffuser nested within a diffuser, together providing uniform back-scattering of sound energy within it’s own frequency range without lobing associated with periodic arrays or unwanted absorption due to viscous losses between wells. Finished profiles are solid core materials to prevent resonances and resist damage with standard or customer specified wood species.

Applications

Prime7™ BiFractal is an ideal solution for rooms and spaces where single-dimension broadband diffusion is desired. Some applications include:

Music Spaces — Recording Studios — Auditoriums — Performing Arts Centers — Lecture Halls — Churches
