The most effective, intelligent, and flexible sound masking available. That’s not just typical sales hyperbole. You’re not just buying speakers and cables, you’re buying great-sounding intelligent privacy. The VoiceArrest™ System simulates the gentle whooshing sound of a high-end HVAC system that covers conversations and other distractions. Because we use speakers designed for music, the sound is full, yet you can’t pinpoint exactly where it’s coming from.
