Sound masking is the addition of an unobtrusive background sound, similar to airflow, to reduce the intelligibility of human speech and reduce distractions. The resulting environment leads to greater productivity and increased privacy and comfort.

With the direct field approach to sound masking, the Qt® system uniformly disperses the masking sound into the space and eliminates masking sound overflow into undesired areas. The pre-tuned masking sound is emitted through four sequenced channels that eliminate acoustic interference. Additionally, our Qt® systems deliver more energy in the octave bands that are related to speech, resulting in a more energy efficient system that successfully masks speech at lower volume levels.
