Abstract: Disclosed herein are systems and methods for eardrum acoustic pressure estimation for hearing device applications. A receiver signal is produced through a receiver of a hearing device, or a physical extension of the receiver, placed inside an ear canal of a user. A microphone signal is sensed, in response to the receiver signal, using a microphone placed outside the ear canal. Based on the receiver signal and the microphone signal, a reliability signal of the microphone signal and a feedback-path signal are computed. A spectral representation signal of the feedback-path signal is computed, and a real-ear response signal is computed using a mathematical combination of the spectral-representation signal and the reliability signal. The computed real-ear response signal is used to modify an operational characteristic of the hearing device, or to make a recommendation for modification of an operational characteristic or a physical characteristic of the hearing device.

Abstract: An audio input signal is digitized via circuitry of an ear-wearable device. An adaptive feedback canceller has an adaptive filter producing an output that is inserted into the digitized audio input signal to cancel feedback. A motion detector provides a motion signal indicative of motion of the car-wearable device. A processor is operable to determine a change in a feedback path based on the motion signal. The processor causes the adaptive filter to have faster adaption in response to the change in the feedback path is above a first threshold. The processor also causes the adaptive filter to have slower adaption in response to the change in the feedback path being below a second threshold.

Abstract: Secondary path measurements and associated acoustic transducer-to-eardrum responses are obtained from test subjects. Both a least squares estimate and a reduced dimensionality estimate are determined that both estimate a relative transfer function between the secondary path measurements and the associated acoustic transducer-to-eardrum responses. An individual secondary path measurement for a user is performed based on a test signal transmitted via a hearing device into an ear canal of the user. An individual cutoff frequency for the individual secondary path measurement is determined. First and second acoustic transducer-to-eardrum responses below and above the cutoff frequency are determined using the individual secondary path measurement and the least squares estimate. A sound pressure level at an eardrum of the user can be predicted using the first and second receiver-to-eardrum responses.

Abstract: A hearing device includes a deep/recurrent neural network trained to jointly perform sound enhancement and feedback cancellation. During training a neural network is connected between a simulated input and a simulated output of the hearing device. The neural network is operable to change a response affecting the simulated output. The neural network is trained by applying the simulated input to the deep neural network while applying the feedback path response between the simulated input and the simulated output. The deep-neural network is trained to reduce an error between the simulated output and the reference audio signal and used for sound enhancement in the device.

Abstract: Disclosed herein, among other things, are systems and methods for artifact detection and tuning of a feedback canceller. A method includes detecting an artifact of a feedback canceller during operation of a hearing device. Artifact data associated with the detected artifact is stored in a memory of the hearing device, the artifact data including information related to the detected artifact and information related to the hearing device during occurrence of the detected artifact. Artifact statistics are computed based on the stored artifact data, and the artifact data and the artifact statistics are transmitted to an external device. Comparison data is received from the external device, including results of a comparison of artifact data or artifact statistics of the hearing device to artifact data or artifact statistics of other devices. Parameters of the hearing device are automatically adjusted based on the comparison data to improve performance of the feedback canceller.

Abstract: Disclosed herein, among other things, are systems and methods for setting acoustic coupling parameters for hearing devices. A method includes producing a receiver signal through a receiver of a hearing device, or a physical extension of the receiver, placed inside an ear canal of a user. A microphone signal is sensed, in response to the receiver signal. Based on the receiver signal and the microphone signal, an estimate of an acoustic coupling characteristic of the hearing device is computed. The estimate of the acoustic coupling characteristic may be compared to stored reference data from a memory or to a second estimate of the acoustic coupling characteristic computed for a second hearing device in a second ear of the user to obtain an improved estimate of the acoustic coupling characteristic. The improved estimate of the acoustic coupling characteristic is used to modify an operational characteristic of the hearing device.
