Acous® SOUND ABSORPTION AND INSULATION SANDWICH PANEL

The experimental results show that when the test range is 100-5000Hz, the average sound absorption coefficient of Acous^® is 0.64, and the noise reduction coefficient NRC is 0.75. Excellent sound absorption performance, indoor noise reduction by 1/3 after application; Noise reduction coefficient of common metal plate NRC=0.15, lower than the classification range; Acous^® Noise reduction coefficient NRC=0.75, belongs to the II level, much higher than the noise reduction coefficient of ordinary metal plate; Noise reduction performance is excellent, close to the plate rock wool noise reduction coefficient NRC=0.85.

Experiments show that the sound insulation performance of Acous^® is 100% higher than that of ordinary sandwich boards when the high-frequency noise transmittance is less than one in 10,000.

PE coated punching plate after 480h neutral salt spray, punching position no corrosion phenomenon, meet the requirements of indoor use.
