Qt™ Systems for Speech Privacy and Office Noise Management

Qt™ Systems for Speech Privacy and Office Noise Management

Qt™ Ceiling-Mounted Speech Privacy Systems are unique in several important dimensions. Qt Systems produce a sound that is so effective in masking speech that the sound produced by these systems is patented. In practice, the sound produced by Qt Systems provides effective masking of speech at much lower sound levels than are required for similar results when using other brand systems. Listen to a clip of the patented Cambridge Masking Sound produced by QT™ Systems.

We recommend ceiling mounted QT Systems for open cubicle spaces over 500 square feet in area, and for installations in which treatment of 4 or more offices is desired. Qt Systems are modular and easily expandable to cover from a single office to a million square feet or more of space. Unlike other ceiling or plenum mounted systems, QT Systems are designed for user-level installation, with no special skills or experience required.

Building a System is Simple and Easy.
Qt Systems require a Qt Control Module (Qt 100, Qt 300, or Qt 600) control module and emitters (special ceiling-mounted speakers) in sufficient numbers to cover the area to be treated. The number of emitters is generally recommended to equal the total area to be treated, divided by the square of the ceiling height. So for example a space with 2,000 square feet total, and a 10 foot high ceiling would need 20 emitters (2000/(10 x 10) = 2000/100 = 20). Both the Qt Control Module and the emitter kits come with all the parts you need to complete your installation. Emitters are adjustable, letting you customize the sound level in each area as needed to achieve your goals of reduced distraction and/or improved speech privacy/confidentiality.
