How perforated Metal Are Used in Acoustics.
|Minimum Order Quantity||1000 Square Feet|
|Usage||Sound Absorbers,Sound Diffusers,Noise Barriers,Sound Reflectors,ACOUSTICAL USES FOR PERFORATED METAL|
Ther are Two principals applications for perforated metal.
A. AS A FACING FOR SOME THING ELCE
B. IN A TUNED RESONENT ABSORBER
A- Here the perforated metal is used as a protective and decoratiive covering for some special acustical material that material may be designed either to absorbe sound or to reflect or scatter sound in a special way so , the purpose of the PERFORATED MATERIAL
in asuch a way application is to be transparant that the sound waves passes through without being diminished or reflected to encounter the acustical treatment that lies behind.
B- The tuned resonant Absorber
In a many ways noice control applications, the objective is to remove or reduce sound that occuring only in a narrow range of frequancy for such situations it is possible to design a sound absorbation system that is tuned to those targatted frequancies in which PERFORATRD METALS PLAYS
a critically active role. This kind of system is called a tuned Resonant Absorber. From ACOUSTICAL USER FOR PERFORATED METALS....
