Product Description

PrivacyShield Speech Privacy Without the Noise!

Speech Privacy Without the Noise!

The PrivacyShield® Light hood is installed over lighting fixtures in a suspended ceiling to reduce sound and noise transmission, while maintaining air flow. Lighting fixtures have been identified as a significant path for speech and noise to enter and exit the ceiling plenum and travel to neighboring enclosed or open rooms.

Light hoods can be installed in both new and existing spaces to reduce the amount of sound transmitted from one space to the next. These are used when wall partitions do not extend up above the ceiling grid to the roof deck and offer an economical alternative to building full partition walls.
