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.
Speech Privacy and Noise Reduction in Private Offices, Conference Rooms, HR Departments, Legal Departments and Medical Facilities.

A little difficult to fully install but I assume partially installed is worth it
it works just like advertised
product was used in a lab. install was and the product was excellent.
We may use it in additional rooms.
I am in an office surrounded by smaller offices and had zero privacy as sound carries so easily. Installation of this products transformed my sound, now my staff thinks I am out of the office when I am having phone conferences and employee meetings.
Not sure you can improve on the product but I wish there was an easier way to marry the pieces rather than liquid brush on adhesive.
