Abstract:
A sound processing system measures one or more periauricular muscle signals from one or more periauricular muscles of a user. Additionally, the sound processing system computes, based on the periauricular muscle signals, an estimate of an angle corresponding to a direction of a current auditory attention locus of the user with respect to a reference point or plane. The sound processing system controls, based on the estimate of the angle, an operating characteristic of the sound processing system.
Abstract:
A computing system comprising one or more electronic computing devices receives data from a hearing-assistance device. The computing system determines, based on the data received from the hearing-assistance device, a cognitive benefit measure for a wearer of the hearing-assistance device. The cognitive benefit measure being an indication of a change of a cognitive benefit of the wearer of the hearing-assistance device attributable to use of the hearing-assistance device by the wearer of the hearing-assistance device. The computing device outputs an indication of the cognitive benefit measure.

Various embodiments of a fall prediction system and method of using such system are disclosed. The system includes a hearing device for a user, a sensor operatively connected to the hearing device and adapted to detect a characteristic of the user and generate a sensor signal based on the characteristic, an accessory operatively connected to the hearing device, and a controller operatively connected to the hearing device. The controller is adapted to determine a fall risk value based on the sensor signal, compare the fall risk value to a fall risk threshold, and generate a fall prevention output if the fall risk value exceeds the fall risk threshold.
Abstract:
A system and method of determining a filter to cancel feedback signals from input signals in a hearing assistance device includes determining feedback signals for a plurality of feedback paths associated with the device, and determining a model of the plurality of feedback paths, with the model having an invariant portion and a time varying portion. A probable structure of the invariant portion is determined to generate a structural constraint to constrain the plurality of feedback paths, and probability distributions to impose the structural constraint on the invariant portion are determined. During an iterative process, the invariant portion is iteratively determined using the determined probability distributions and the feedback path measurements. A measurement noise variance representative of model mismatch is updated, for each iteration, to reduce a probability of a non-desirable determination of an invariant filter, and the invariant filter is determined in response to a criterion for ending the iterative process being satisfied.
