Description
A highly durable, abuse resistant perforated metal acoustic panel. Available with a flat or V-groove surface.
Kinetics Model KNP Acoustic Panel Absorbers are functional and aesthetically pleasing perforated panels which are used to control reverberant noise problems in factories, waste water treatment facilities, pump rooms, equipment yard barrier walls and other factory and enviromental applications. Although primarily intended as an absorber, the panels will act as a barrier when a solid back is added. KNP acoustic panels are also useful as additions to existing metal or concrete barriers to reduce reverberation time and to lower reflected sound.
