Exploring the Impacts of Consistency in Sound Masking


  • Niklas Moeller K.R. Moeller Associates Ltd.


Electronic sound masking systems control the noise side of the signal-to-noise ratio in interior environments.  Their effectiveness relates directly to how consistently the specified masking curve is achieved.  Current system specifications generally allow a relatively wide range in performance, in large part reflecting expectations set by legacy technologies.  This session presents a case study of sound masking measurements and speech intelligibility calculations conducted in office spaces.  These are used as a foundation to discuss the impacts of local inconsistencies in the masking sound and to begin a discussion of appropriate performance requirements for masking systems.
