Sound masking is the process of adding background sound to reduce noise distractions, protect speech privacy and increase office comfort. By adding sound masking to a workplace, conversations are notably less intelligible or noticeable, and thus less distracting. The workplace becomes more comfortable, private, and productive. Telephone & Network Technologies partners with Cambridge Sound for all our sound masking needs. The offer top of the line products for emitters as well as the QT 300 and QT 600.
