Introducing the QtPro®, one of Cambridge Sound Management’s sound masking solutions. The QtPro® is direct-field sound masking and uniform coverage. The Modern loud speaker driver technology allows small, barely-noticeable sound masking emitters that are unaffected by objects with variations in the ceiling or plenum.



Phase Integration doesn’t resell product, which allows us to provide unbiased recommendations based on functionality, timeline and budget. We are dedicated to making our customers the number one priority, which is why we look to manufacturers such as Cambridge Sound Management.

Precise, uniform sound masking coverage

QtPro® systems provide precise control over where the masking sound is emitted. This means that sound masking is dispersed only in the spaces in which it is needed, eliminating unwanted spill over into adjacent spaces. The system provides a uniform blanket of sound coverage throughout the work space and is unaffected by ceiling design. The sound is transmitted as four uncorrelated channels, creating a more pleasant and comfortable masking sound to reduce noise distractions and protect speech privacy.

Versatile, flexible to work in extraordinary spaces

Qt® emitters can be installed into any work space, no matter what type of ceiling is present. The system is designed to grow and change with your business. Qt emitters can be moved and reconfigured with minimal effort and impact when your work space changes.

Sound masking is precisely tuned to the frequency of human speech, so it can effectively mask human speech. Often misunderstood as white noise, sound masking is at a more comfortable frequency range

Simple, low impact installation

Qt® emitters are installed along a simple grid pattern with space determined by ceiling height. In new construction or in existing space, emitters can be installed rapidly and with low impact to the surroundings and little to no down-time for the business.

Designed to adapt

The Qt® system is designed to grow and change with your business. Qt emitters can be moved and reconfigured with minimal effort and impact when your work space needs to change.

Integrated paging and music

Qt® systems integrate paging and music functionality, making this 3-in-1 system a complete solution for creating better acoustic environments.

Energy efficient

Quiet Technology is the most environmentally friendly sound masking system on the market. All Qt® systems are GreenSpec listed for their energy efficiency. Qt can also contribute to your facility’s LEED certification by improving your acoustic environment and can mitigate the acoustic challenges created by some LEED requirements.

Pre-tuned, saving valuable time and money

Each Qt® system comes pre-tuned with our masking spectrum, specifically calibrated to efficiently mask the frequencies most commonly associated with the human voice.

Industry standards

Qt® Quiet Technology meets:

  • The DCID 6/9 Requirements for helping organizations reach a Sound Transmission Coefficient (STC) of 45 or better (sound groups 3 & 4) to secure verbal communications in Government and Military installations.
