摘要： Disclosed herein, among other things, are systems and methods for active noise cancellation (ANC) for hearing device applications. A method includes measuring a receiver-to-inward-facing microphone response during an in-situ calibration stage for the hearing device, estimating a receiver-to-eardrum transfer function using the measured receiver-to-inward-facing microphone response, and measuring an outward-facing microphone to inward-facing microphone transfer function for an external noise sound field during run-time operation of the hearing device. The method also includes estimating an inward-facing microphone to eardrum transformation for the external noise sound field in the inward-facing microphone using the measured outward-facing microphone to inward-facing microphone transfer function, computing an ANC controller using the estimated receiver-to-eardrum transfer function and the estimated inward-facing microphone to eardrum transformation, and cancelling acoustic noise for the hearing device using the ANC controller.

摘要： Disclosed herein, among other things, are systems and methods for active noise cancellation (ANC) for hearing device applications. A method includes estimating a first sound pressure on an ear drum of a wearer of the hearing device caused by a hearing processing signal, estimating a second sound pressure on the ear drum of the wearer of the hearing device caused by a leakage path of the hearing device, and computing a ratio of the first sound pressure and the second sound pressure to predict a comb-filtering effect for the hearing device. The method also includes computing an ANC controller using the computed ratio in one or more frequency ranges, and canceling leaked sound into an ear canal of the wearer for the hearing device in the one or more frequency ranges using the ANC controller.

摘要： Disclosed herein, among other things, are methods and apparatus for providing a time-stamp based controller for synchronization of sink or source sampling rate with external packet rate. A method for wireless communications includes receiving a transmission of a packet using a wireless transceiver of an electronic device, and using a processor of the electronic device to read a first value of a system timer and store the first value as an arrival time-stamp. The packet is decoded and processed by the processor, and sent to an output. When the processed packet is sent, a second value of the system timer is read, adjusted and stored as a departure time-stamp. The arrival time-stamp and the departure time-stamp are used to calculate an adjustment stimulus for a sample rate actuator of the electronic device. The sample rate actuator is configured to maintain synchronization of sampling rate with an external packet rate.

摘要： A hearing device may include an earpiece, and ear-tip suspension element disposed in the earpiece, a solenoid actuator, and a controller. The earpiece and the ear-tip suspension element may include passageways that connect to form a vent through the earpiece. The solenoid actuator may include a solenoid and a core. The core may be movable between an open position and a closed position to open and close the vent. The controller may include one or more processors and may be operably coupled to the solenoid actuator to control movement of the core between the open and closed position. The controller may be configured to move the core using the solenoid based on at least a listening environment of the hearing device.

摘要： A processing system determines, based on a set of input datapoints, a current state of charge (SOC) of a battery of a hearing instrument. Additionally, the processing system determines a predicted agenda of the hearing instrument, the predicted agenda comprising one or more future time segments. The processing system estimates, based on the current state of charge and the predicted agenda of the hearing instrument, an amount of time remaining until the future SOC of the battery of the hearing instrument reaches a threshold.

摘要： A hearing device includes a microphone that produces an audio input signal and a loudspeaker that outputs an amplified audio signal into an ear canal. A signal processing path is coupled to the microphone and the loudspeaker. The signal processing path includes a deep neural network configured to predict an instantaneous gain margin of the hearing device based on a set of inputs. The set of inputs includes a first parameter of the audio input signal, a second parameter of the amplified audio signal, and a gain of the signal processing path. A feedback reduction module of the device receives the predicted instantaneous gain margin and adjusts feedback reduction parameters to reduce an onset of feedback in the hearing device
