Description

A highly durable perforated metal acoustic panel. Ideal solution to airborne noise problems in demanding environments. Suitable for indoor and outdoor applications. Cleanable/wipeable surface. Available with flat or V-groove face.

KNP sound absorbing panels are functional and aesthetically pleasing perforated panels which are used to control reverberant noise problems. Although primarily intended as an absorber, KNP perforated metal panels will act as a barrier when a solid back is added. KNP sound absorbing panels are useful as additions to existing metal or concrete barriers to reduce reverberation time and to lower reflected sound.

KNP perforated metal panels can be attached to walls, ceilings, or other surfaces and can be located in a manner to achieve an aesthetically pleasing pattern. Kinetics sound absorbing panels are available with optional rear backing to increase transmission loss and be used as a barrier. Available faced with perforated material on both sides and used as hanging absorptive baffles.
