Dynasound has pioneered the development of sound masking systems since 1975. Our sound masking systems increase worker concentration, productivity & accuracy while reducing distractions. Our addressable system is the industry's only to utilize industry standard networks (Cisco, NETGEAR, etc.), incorporate Power over the Ethernet (PoE) to eliminate costly in-plenum, 120 Volt power drops while providing cost effective control of ALL speakers independently (volume, spectrum and audio functions). Our EAVESDROPPING PROTECTION SYSTEMS protect sensitive & classified (SCIF) conversations against human & electronic eavesdropping. We protect windows, walls, doors, HVAC ducts, pipes and plenums (ceiling & floor). The process begins with our award winning "Acoustical Programming Software" to quantify and value engineer speech privacy performance requirements. Our systems are designed for today and engineered for tomorrow.
