Abstract
A system for enabling a person to speak privately in a confined space having a plurality of listening zones includes a sound-generating unit, a person-detecting unit configured to detect a first location of the person within the confined space and to generate a first signal containing information indicative of the first location, and a processor operatively coupled with the sound-generating unit and communicatively coupled with the person-detecting unit. The processor is configured to obtain the first signal from the person-detecting unit, to identify a first listening zone of the plurality of listening zones where the person is located based on the first signal, and to control the sound-generating unit to emit the sound into a second listening zone of the plurality of listening zones. The sound is configured to render a conversation had by the person in the first listening zone substantially inaudible from the second listening zone.
