Cambridge Sound Management Inc. is the developer of Qt Quiet Technology™ sound masking systems.

CSM offers innovative, simple and intelligently designed solutions to the problems of privacy and acoustic distractions. Qt Quiet Technology combines exceptional audio performance, low impact installation, and affordability. Qt™ systems consume less power than a 40 watt light bulb per 16,723 metres squared.

CSM has a distinguished heritage in the field of acoustics, as a descendant of the highly regarded Bolt, Beranek and Newman's acoustics consulting group that was founded in 1948.

This group of distinguished acousticians received the American Institute of Architects Honor Award as recognition for having "...created an awareness of acoustical considerations in building design... and integrating solutions based on scientific principles with architectural and artistic concepts."
