ACOUSTIC CERTIFICATES

The accreditation of Perfopan products has acoustic certificates tested in with international criteria. In acoustic panel tests, each model is subjected to different tests. The system we recommend in wooden acoustic panel application is to add rock wool to the back of the panels. The values given in our reports are American Standards, NRC- (Noise reduction coefficient), SAA (Sound Absorption Average) values and XW sound absorption values in European standards. In the graphs we give in the technical information section, the X axis shows the resonance frequency, and its unit is Hertz- (Hz). Y-axis shows the amount of sound absorption coefficient, and its unit is called Sabin (as).
