PrivacyShield™ Speech Privacy Without the Noise!Speech Privacy Without the Noise!

The PrivacyShield™ Plenum Return Silencer G2 stops airborne sound transmission through ceiling grid air returns to increase speech privacy. As a component of the PrivacyShield™ system, use this in combination with the PrivacyShield™ Ceiling Tile Barrier and Light Hoods to prevent sound from flanking over interior partition walls. Unlike other speech privacy systems, like sound masking, creating a soundproof ceiling grid provides a better, long-lasting alternative without adding fatiguing noise.

By and large, open plenum ceiling grid systems are intended to provide a low cost air return solution for office spaces and buildings. What is often overlooked is the need for speech privacy and sound control. Given that an open air return permits air to cycle into the plenum, but by the same token, it also allows any sound and conversations to pass with it. This is especially the case when the partition walls do not extend up to the roof deck.  To address this issue, something needs to be placed at the sound source to prevent this sound transmission.

As the next generation of air silencers from Acoustical Solutions, the unit was specifically designed to provide a solution to this problem. As the air and sound enter the silencer, it is presented with a tortured path of sound absorbing material. Consequently, the sound is reduced and prevented from escaping to other rooms, while maintaining air flow.

As a result of soundproofing your grid, you can keep your conversations confidential and prevent annoying distractions that will lead to increased privacy and productivity as well as create a comfortable, relaxing space.

For use in standard 2’x2′ and 2’x4′ grids systems, the PrivacyShield™ Plenum Return Silencer G2 is available for new or retrofit construction projects. Each shipment includes a pre-cut barrier tile backer, a vertical air chute with included 5″ corner extensions, your choice of standard hood or hood with a 1 lb. per sq. ft. barrier septum and tape for assembly.
