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 -
