Office Ceiling Aluminum Micro Perforated Acoustic Panel Interior Soundproofing Building Material

Micro Aluminum Perforated Acoustic Panel :Seamless Acoustical Ceiling and Wall System gives you the design flexibility and monolithic visual of gypsum board in a sound reducing alternative. Treat it like gypsum board, enjoy the performance.Excellent acoustical performance Fine texture finish provides and smooth, uninterrupted appearanceSimilar installation and finishing methods to gypsum board- for the easiest installationThe microperforated product adopts the microperforated sound absorption concept proposed by the academician Ma Daxuan of China, who is a famous international acoustician . The micro-wave structure on the surface of micropores changes the transfer path under the clever arrangement of the shin and the rib, absorbing a large amount of particle impact energy, and the micro holes in the trough cause the particles to be squeezed and rubbed because of the speed difference caused by the oblique microperforated acoustic impedance effect which will lead to the loss of kinetic energy when particles are penetrated. The remaining energy particles after penetration also cause particle viscous effect and diffusion interference due to the 500,000 "geometric surfaces" per square meter on the backside resonate in the cavity , allowing the sound energy to decay in the process of resonance in cavity to achieve good sound absorption.Core : AluminumAuminum Thickness :0.6mm - 1.2mmFinish : Wood grain grain / Pure colorCoating :Clear anodized , Mil finish for power coatApplication :Wall and ceilingPanel size : Length max 3000mmEdge detail : Square , BeveledCertificates : ISO , SGS , Interket , ASTM etcDelivery time : Standard 15 days Payment term : TT, LC at sightMore service : OEM , ODMMain production : Acoustic panelAbout NRC Test Method :Measurement according to ASTM C423-07a Standard Test Method for Sound Absorption and Sound Absorption Coefficients by the Reverberation Room Method  OR  The measurements were carried out according to BS EN ISO 354 : 2003 Acoustics Measurement of Sound Absorption in a reverberation room (equivalent to GB/T 20247-2006) in the Acoustic Testing Services Limited .
