Abstract

A hands-free intercom may include a user-tracking sensor, a directional microphone, a directional sound emitter, a display device, and/or a communication interface. The user-tracking sensor may determine a location of a user so the directional microphone can measure vocal emissions by the user and the directional sound emitter can deliver audio to the user. The hands-free intercom may provide privacy to the user. The hands-free intercom may prevent an eavesdropper from hearing the user's vocal emissions, for example, by canceling the vocal emissions at the eavesdropper's ear. The directional sound emitter may deliver out-of-phase sound to cancel the vocal emissions. The hands-free intercom may also, or instead, cancel ambient noise at the user's ear. The hands-free intercom may measure or predict a filtration of the sound to be canceled and compensate for the filtration when canceling the sound.
