Advanced acoustic and scientific knowledge led to the development of our patented sound masking systems. Below, through our series of Tech Notes, you’ll learn more about the science behind our systems directly from our engineers.
Disabling Sound Masking in an Emergency
All Cambridge Sound Management sound masking systems have a method where sound masking may be disabled in the event of an emergency announcement. This document describes a code compliant method of which this feature may be implemented when requested.Download»
Addressing Sound Masking Requirements in the National Fire Alarm and Signaling Code® and UL Standards
This Tech Note will provide an awareness level of information about NFPA 72 as well as how the Code integrates with the UL requirements found in ANSI/UL 864 and ANSI/UL 2572, Sound masking systems are not required to comply with UL 2572 or UL 864 when a sound masking system is interfaced with an MNS or a fire alarm system.Download»
Speech Privacy Standards
As employees in open office environments are more frequently reporting speech/acoustic privacy concerns, there becomes a need to understand what employees are experiencing and how to best define and measure acoustic privacy.Download»
Sound Masking Health and Safety Overview
Does sound masking have any adverse health effects? The short answer is “no, sound masking is perfectly safe,” but a more detailed explanation follows.Download»
