dur-SONIC® TUBE is used to improve the acoustics in rooms with open ceiling systems. As a broad-band absorber it is suitable for rooms with a high noise level, such as canteens or open-plan offices. The absorber improves room acoustics in all frequency ranges by reducing resonance times and, depending on installation density, it can achieve NRC values of up to 0.95.
