    Abstract: A device includes an ear occlude, an output transducer that is acoustically coupled to an ear canal of a wearer of the device, a voice microphone configured to generate a first electrical signal that is proportional to a voice-generated sound pressure at the microphone, and signal processing circuitry, electrically coupled to the output transducer and the microphone, including a compensator configured to generate, from the first electrical signal, a second electrical signal, and output the second electrical signal to the output transducer, wherein the compensator is tuned to cause GOE, a ratio of a sound pressure within the ear canal to a voice-generated sound pressure at a mouth reference point when the ear is occluded and electronically-aided to be approximately equal to GU, a ratio of the sound pressure within the ear canal to the voice-generated sound pressure at the mouth reference point when the ear is unoccluded.

    Abstract: A noise cancelling headset includes an earpiece, the earpiece including a feedback microphone, a feed-forward microphone, and an output driver. A first feedback filter receives an input from at least the first feedback microphone and produces a first filtered feedback signal. A first feed-forward filter receives an input from at least the first feed-forward microphone and produces a first filtered feed-forward signal. A first summer combines the first filtered feedback signal and the first filtered feed-forward signal and produces a first output signal. An output interface provides the first output signal as an output from the headset.

    Abstract: A method and system for a noise cancellation comprises an amplifier in communication with the three or more speakers disposed in an area. A system controller produces a driver signal for each of the speakers in response to a signal from at least one microphone detecting sound in the area and communicates the driver signals to the amplifier. The amplifier drives each speaker with the driver signal produced for that speaker. In response to the driver signals, the speakers emit sound that combined produces a substantially uniform sound pressure field for a particular zone within the area. The substantially uniform sound pressure field produced by the speakers has a magnitude and phase adapted to attenuate a noise field in the area corresponding to the sound detected by the at least one microphone.

    Abstract: A portable system for enhancing communication between at least two users in proximity to each other includes first and second noise-reducing headsets, each headset including an electroacoustic transducer for providing sound to a respective user's ear and a voice microphone for detecting sound of the respective user's voice and providing a microphone input signal. A first electronic device integral to the first headset and in communication with the second headset generates a first side-tone signal based on the microphone input signal from the first headset, generates a first voice output signal based on the microphone input signal from the first headset, combines the first side-tone signal with a first far-end voice signal associated with the second headset to generate a first combined output signal, and provides the first combined output signal to the first headset for output by the first headset's electroacoustic transducer.
