The LogiSon Acoustic Network is a digital sound masking, paging and music system. It distributes an engineered background sound that improves speech privacy and reduces noise disruptions in the workplace, increasing both comfort and concentration. The Network is easily installed in new or existing facilities of any size, providing an effective way of addressing acoustical issues as nominal cost and without large-scale remodeling. It provides the most sophisticated level of component integration in the industry, allowing the masking sound to be custom-tuned to your environment. It offers networked control down to individual, addressable speakers. All settings are programmed using a central control panel or laptop. There is no need to access the ceiling in order to rezone or retune, providing speed, ease and versatility.
