Dynasound’s DS2022 return-air grill attenuator is designed for quick and easy installation into ceiling return-air grills in 2x2 suspended ceiling grid systems. The DS2022 is used to acoustically treat open return-air grills for sound masking uniformity by attenuating the amount of sound that can pass directly through. The DS2022 is sized for a standard 2'-0"x2'-0" return-air ceiling grill. Its center perforation allows for the attenuator’s steel planes to pitch upward and create a deflective effect when an acoustical hot spot poses a uniformity problem. When properly installed the DS2022 will attenuate as much as 10 decibel (dB) of sound. The DS2022 is also used to minimize cross-talk between adjacent closed offices or closed offices bordering open office areas.
