  • Patent number: 10764668
    Abstract: An adjustable sensor mount and associated headset that may include a band with circumaural earcups and cushions may be configured to position a sensor forward of the tragus of a user. The headset may include a speaker, a microphone, and a controller. The mount may include a base configured for sliding engagement with the cushion and a sensor holder secured to the base and configured to receive the sensor. The base may be made of a generally C-shaped resilient plastic or metal material. The holder may be pivotably secured and/or slide relative to the base. The holder may include a support arm that slides and/or pivots relative to the base and receives a housing adapted to secure the sensor. The housing may slide and/or rotate relative to the support arm, and may have an elastomeric covering. Sensor signals may be processed to provide a gating signal for the microphone.

  • Patent number: 9191732
    Abstract: An active-noise-reduction (ANR) headset includes at least one auxiliary connection to an output of at least one device, such as a personal communications, computing, and/or entertainment device. An exemplary headset also includes a primary connection to a two-way radio or public-address system and circuitry for automatically suppressing or muting the volume of an auxiliary input signal relative to that of a primary input signal. Other exemplary features include a headset power supply, a microphone, a microphone preamplifier, and a device-detection circuit. The device-detection circuit selectively couples the power supply to the microphone preamplifier, enabling it to provide audio signals to the microphone input of the auxiliary device.

  • Patent number: 8320591
    Abstract: An innovative automatic-noise-reduction headset includes numerous enhancements. For example, one embodiment includes added noise-control circuitry at each of one or more auxiliary inputs to reduce audible hiss in the earcups. Another embodiment includes integrated crossfeed processing circuitry to enhance the spatial imaging of stereo audio perceived by headset users. Still another embodiment provides superior perception of noise cancellation by focusing noise cancelling at midband frequencies, such as 400-800 Hertz, as opposed to just lower frequencies. And another embodiment provides earcups formed of magnesium or a magnesium alloy for improved strength-weight as well as passive noise attenuation in the 400-800 Hertz range.

  • Patent number: 7907721
    Abstract: Headsets are used in variety of applications to facilitate one- or two-way audio communications between users and/or devices. The present inventor recognized that conventional headsets lack means for successfully integrating more than one audio source, despite their use in proximity to multiple sources of audio signals, such as cell phones, laptops, aircraft radios, and so forth. Accordingly, the present inventors devised one or more devices, circuits, and methods related to connection of at least two audio input signals to a headset. For example, in one embodiment, an active-noise-reduction (ANR) headset includes at least one auxiliary port for connection to an output of at least one device, such as a personal communications, computing, and/or entertainment device. This exemplary headset also includes a primary port for connection to a two-radio or public-address system and circuitry for automatically suppressing or muting the volume of an auxiliary input signal relative to that of a primary input signal.

  • Patent number: 7317802
    Abstract: Active-noise-reduction (ANR) headsets protect the hearing of their users from loud persistent noises, such as airplane engines and construction equipment. These headsets generally include ear speakers and special circuitry to cancel or suppress certain types of loud persistent noises. One problem the present inventor recognized with active headsets, particularly those manufactured in mass quantities, concerns the performance variations that stem from inevitable variations in the fit of their earcups against heads of their users. For example, in putting on and taking off these headsets, some users experience low-pitched noises. Accordingly, the inventor devised, among other things, headsets that include front-cavity vents for equalizing the pressure between a front cavity portion of an earcup and an ambient environment.
