Recent studies have found that more than 75% of all workers in open-plan offices are distracted by out-of-office conversations. Sound masking technology, proven effective in thousands of open office installations, constructively adds background noise to dramatically reduce remote speech intelligibility. Experiments show that when office background noise increases, the clarity of intrusive speech decreases and distractions are reduced. The Sonet sound masking systems (APS) unique technology achieves this interference with a minimal increase in acoustic background level. © Cambridge Sound Management 27 Moulton Street Cambridge, Massachusetts 02138 800 / 219-8199 617 / 349-3779 telephone 617 / 349-3788 fax info@cambridgesoundmanagement.com
