The HiPer Panel®,
(Flat Panel Diffuser) combines absorption and
diffusion into one sound panel. This device is
similar in appearance to standard fabric-covered
acoustical wall panels, such as Sonora®, and can
be intermixed with them.
Acoustical performance differs significantly
from outward panel appearance. The patented
internal structure uses two layers of
absorption, separated by a barrier septum, to
form a low-profile, composite absorber /
diffuser product.
The layers have a pattern of wells that yield an
equal distribution of absorptive and reflective
regions, both vertically and horizontally. Their
constructive and destructive interference with
incident sound, produced by the varied
hole-pattern combinations, creates significant
sound scattering in the critical
mid-frequencies. |
