Implant system
A compensation system for an implantable actuator is disclosed where the implantable actuator includes a sealed housing containing a driving arrangement for the actuator. The compensation system includes an external pressure sensor for measuring an external pressure outside of the sealed housing and a compensation module for determining a compensation factor for the implantable actuator based on the external pressure. In one embodiment, the compensation is directed to a direct acoustic cochlear stimulation (DACS) implantable actuator.
Ear-worn electronic device incorporating motor brain-computer interface
An ear-worn electronic device comprises a plurality of EEG sensors configured to sense EEG signals from or proximate a wearer's ear. At least one processor is configured to detect, during a baseline period of no wearer movement, EEG signals from the EEG sensors, and detect, during each of a plurality of candidate control movements by the wearer, EEG signals from the EEG sensors. The at least one processor is also configured to compute, using the EEG signals, discriminability metrics for the candidate control movements and the baseline period, the discriminability metrics indicating how discriminable neural signals associated with the candidate control movements and the baseline period are from one another. The at least one processor is further configured to select a subset of the candidate control movements using the discriminability metrics, each of the selected control movements defining a neural command for controlling the ear-worn electronic device by the wearer.
Hearing aid for placement in a user's ear canal
A hearing aid for placement in an ear canal of a user, includes: a shell; a faceplate comprising an upper face, and a lower face, and a circumference, the upper face being exposed when the shell is placed in an ear of the user; a coil arranged at the faceplate; and a button arrangement comprising a plunger configured to control an integrated circuit arranged below the coil, the coil comprising one or more windings, the one or more windings being circumferential of an inner cavity of the coil with respect to a center or longitudinal axis of the coil, the button arrangement being configured such that the plunger in at least one position extends through the inner cavity of the coil for engaging the integrated circuit.
Binaural hearing system having two hearing instruments to be worn in or on the ear of the user, and method of operating such a hearing system
A binaural hearing system for assisting a hearing of a user includes two hearing instruments each to be worn in or on an ear of the user. An audio signal is modified in each of the two hearing instruments by way of a programmable signal processor of the respective hearing instrument by executing a plurality of software modules of firmware of the hearing system and is output by an output transducer of the respective hearing instrument. The executed software modules of the firmware are distributed asymmetrically on the two hearing instruments, so that at least one of the software modules of the firmware is selectively executed in one of the two hearing instruments.
Binaural hearing system for providing sensor data indicative of a physiological property, and method of its operation
The disclosure relates to a hearing system including a first hearing device configured to be worn at a first ear of a user and a second hearing device configured to be worn at a second ear of the user. The first hearing device includes a first physiological sensor configured to provide sensor data indicative of a physiological property of the user and the second hearing device includes a second physiological sensor configured to provide sensor data indicative of the same physiological property as the sensor data provided by the first physiological sensor. A processing unit may be configured to control the first and second physiological sensor to alternatingly provide the sensor data in subsequent time intervals.
Feature extraction in hearing prostheses
Presented herein are techniques for extracting features from sound signals received at a hearing prosthesis at least partially based on an environmental classification of the sound signals. More specifically, one or more sound signals are received at a hearing prosthesis and are converted in to stimulation control signals for use in delivering stimulation to a recipient of the hearing prosthesis. The hearing prosthesis determines an environmental classification of the sound environment associated with the one or more sound signals and is configured to use the environmental classification in the determination of a feature-based adjustment for incorporation into the stimulation control signals.
Method for operating a hearing device
A method is disclosed for operating a hearing device, comprising a receiver and an active vent. The method includes 1) upon request to switch the active vent into a different state, estimating a transfer function (H, H.sub.rec.fwdarw.mic) from the receiver to obtain a first transfer function (Ĥ.sub.a), 2) subsequently switching the active vent, 3) subsequently estimating a transfer function (H, H.sub.rec.fwdarw.mic) from the receiver to obtain a second transfer function (Ĥ.sub.b), 4) comparing the first transfer function (Ĥ.sub.a) to the second transfer function (Ĥ.sub.b) to obtain a divergence measure (D), 5) concluding that the active vent has actually been switched into the different state if the divergence measure (D) exceeds a threshold (D.sub.diff).
End-to-end deep neural network for auditory attention decoding
In one aspect of the present disclosure, method includes: receiving neural data responsive to a listener's auditory attention; receiving an acoustic signal responsive to a plurality of acoustic sources; for each of the plurality of acoustic sources: generating, from the received acoustic signal, audio data comprising one or more features of the acoustic source, forming combined data representative of the neural data and the audio data, and providing the combined data to a classification network configured to calculate a similarity score between the neural data and the acoustic source using one or more similarity metrics; and using the similarity scores calculated for each of the acoustic sources to identify, from the plurality of acoustic sources, an acoustic source associated with the listener's auditory attention.
Remote microphone devices for auditory prostheses
Presented herein are techniques for adapting settings/operations of a remote microphone device associated with an auditory prosthesis based on a desired/preferred listening direction of a recipient of the auditory prosthesis. More specifically, an auditory prosthesis worn by a recipient and a remote microphone device, which are configured to wirelessly communicate with one another, are both positioned in the same spatial area. At least one of a recipient-specified (e.g., recipient-preferred) region of interest within the spatial area, or a recipient-specified listening direction, is determined. Based on a determined relative positioning (e.g., location and orientation) of the remote microphone device and the auditory prosthesis, operation of the remote microphone device is dynamically adapted so that the remote microphone device can focus on (e.g., have increased sensitivity to) sounds originating from the recipient-specified region of interest/listening direction.
Sound modification based on direction of interest
Techniques for modifying sound based on a direction of interest include determining a direction of interest associated with a user; receiving a set of audio signals associated with the direction of interest; determining one or more salient frequency bands within the set of audio signals; in response to receiving a command from the user to enhance or suppress the set of audio signals, enhancing or suppressing a portion of the set of audio signals corresponding to the one or more salient frequency bands to create a modified set of audio signals; and outputting the modified set of audio signals.
