Abstract: Systems and methods for controlling an environment of a vehicle receive information about a characteristic of at least one of the vehicle's operation, the vehicle's location, and an operator of the vehicle. The information is analyzed to assess a driving condition. An environmental setting of the vehicle is adjusted based upon the assessed driving condition.

Abstract: The present disclosure provides hearing assistance devices and methods of generating a resonance within hearing assistance devices that use moving coil drivers, e.g., electro-dynamic coil drivers. As small moving coil drivers are typically inefficient within the voice band of frequencies, e.g., above 1 kHz, the hearing assistance devices described herein utilize the resonance of a mass within the hearing assistance device and a compliance of air within the housing of the hearing assistance device or within portions of the acoustic driver housing to aid in amplification of select frequencies within the voice band of human speech, e.g., between 2.5 kHz and 6 kHz. By using the assistance of the resonance created, the moving coil driver utilized does not need to operate as efficiently within the range of resonance frequencies.

Abstract: Aspects of the present disclosure provide techniques, including devices and system implementing the techniques, to provide feedback to a user of an event when the user is wearing a wearable device. For example, the wearable device may provide high quality noise canceling audio playback to the user, lowering the user's situation awareness. The techniques include measuring ambient sound using two or more microphones on the wearable device. The measured ambient sound is used to determine a related event worth relaying to the user. Based on the location attribute and sound properties, the nature and/or classification of the event may be ascertained using pattern recognition algorithms according to user threshold settings. Insignificant events that the user prefers to ignore will be ruled out by the algorithm. Upon determining the event that merits the user's attention, the wearable device provides feedback to the user indicating the nature and location of the event.

Abstract: A flexible arm that is configured to be located between and physically and electrically connect an acoustic module of an open-ear headphone to a battery housing of the open-ear headphone. The flexible arm defines an original resting length and position between the acoustic module and the battery housing. The flexible arm includes a flexible printed circuit that extends through the entire original resting length of the flexible arm and comprises a conductor that is configured to carry electrical energy between the acoustic module and the battery housing, and a flexible material that encases at least some of the flexible printed circuit. The length of the flexible printed circuit within the flexible arm is greater than the original resting length of the flexible arm. The flexible printed circuit can thus better accommodate tension or compression on the flexible arm as the flexible arm is bent from its original resting position.

Abstract: Aspects of the present disclosure provide techniques, including devices and systems implementing the techniques, for detecting a current state of a wearable audio device of a user. One example technique for detecting the current state of the wearable device generally includes transmitting, with a driver, at least one pulsed signal associated with the current state, receiving, at a microphone, a received signal of the at least one pulsed signal, determining an acoustic signal associated with the current state based on the received signal, determining a difference between the acoustic signal associated with the current state and a prior acoustic signal associated with a known state, and determining the current state of the wearable audio device based, at least in part, on a comparison of the difference to a threshold. In some aspects, the at least one pulsed signal comprises at least one pulsed ultrasonic wavelet.

Abstract: A first input signal captured by one or more sensors associated with an ANR headphone is received. A frequency domain representation of the first input signal is computed for a set of discrete frequencies, based on which a set of parameters is generated for a digital filter disposed in an ANR signal flow path of the ANR headphone, the set of parameters being such that a loop gain of the ANR signal flow path substantially matches a target loop gain. Generating the set of parameters comprises: adjusting a response of the digital filter at frequencies (e.g., spanning between 200 Hz-5 kHz). A response of at least 3 second order sections of the digital filter is adjusted. A second input signal in the ANR signal flow path is processed using the generated set of parameters to generate an output signal for driving the electroacoustic transducer of the ANR headphone.

Abstract: An apparatus includes a noise reduction headphone comprising one or more microphones and an acoustic transducer, the one or more microphones configured to generate an input signal; and a controller comprising one or more processing devices, the controller configured to: process the input signal through one or more noise reduction filters to generate a noise-reduction signal, compare the input signal to an estimate of ambient noise to determine if the energy of the input signal is greater than the estimate of ambient noise, wherein if the energy of the input signal is greater than the estimate of ambient noise by a predetermined amount, a change in the noise reduction signal is suppressed; and generate an output signal, the output signal comprising, at least in part, the noise-reduction signal, wherein the acoustic transducer is configured to produce an acoustic output in accordance with the output signal.

Abstract: A wind noise reduction system including a beamformer, a comparator, and a voice mixer is provided. The beamformer may be an MVDR beamformer, and generates a beamformed signal based on a first microphone signal and a second microphone signal. The comparator generates a comparison signal based on the beamformed signal and a wind microphone signal. The comparison signal may be further based on a beamformed energy level of the beamformed signal and a wind energy level of the wind microphone signal. The voice mixer generates an output voice signal based on the beamformed signal, the wind microphone signal, and the comparison signal. The wind noise reduction system may further include a wind microphone corresponding to the wind microphone signal. The wind microphone may be arranged on a portion of a wearable audio device configured to be seated in a concha of a wearer.
