Abstract: A hearing aid and a method performed by a hearing aid including at least one microphone unit, an accelerometer unit, and a processor. The method performed by the hearing aid includes generating a processed microphone signal including attenuating the microphone signal in accordance with an attenuation value; wherein the attenuation value is based on a measure of correlation between a microphone signal from the microphone unit and an acceleration signal from the accelerometer unit. The hearing aid instantly reduces noise arising from mechanical handling of the hearing aid based on input from the microphone unit and the accelerometer unit.

Abstract: A hearing aid includes a feedback control system for handling external feedback from an output transducer to an input transducer. The feedback control system includes an open loop gain estimator for providing an instant open loop gain estimate; an adaptive filter configured to provide a current estimate of the feedback path transfer function; a feedback change estimator configured to provide an instant estimate of the feedback path transfer function in dependence of the forward path transfer function, the instant open loop gain estimate; and an adaptive filter controller for providing an update transfer function estimate for the adaptive filter in dependence of the instant estimate of the feedback path transfer function. The hearing aid is configured to use the update transfer function estimate in the adaptive filter to update the current estimate of the feedback path transfer function. A method of detecting a sudden change in a feedback/echo path is further disclosed.

Abstract: A hearing device, e.g. a hearing aid, comprises an input transducer for providing an electric input signal representative of a sound in the environment of the hearing device, an output transducer for providing an output sound representative of said electric input signal, a signal processor operationally connected to the input and output transducers, and forming part of an electric forward path for processing said electric input signal and providing a processed electric output signal, and a feedback detector for providing first and second indications of current feedback in an external—acoustic and/or mechanical—feedback path from said output transducer to said input transducer. The feedback detector is configured to determine the first and second indications of current feedback, respectively, based on said electric input signal or a processed version thereof and—optionally—on a current open loop magnitude of a feedback loop defined by said forward path and said external feedback path. The first and second indications of current feedback are generated with first and second time constants, respectively, where the first time constant is larger than the second time constant. The application further relates to a method of estimating feedback in a hearing device.

Abstract: The application relates to a hearing aid system comprising a hearing aid device comprising a configurable signal processing unit, a programming device configured to program the configurable signal processing unit, and a communication link allowing the exchange of data between the hearing aid device and the programming device. The application further relates to a method of programming configurable signal processing unit to provide an increased speech intelligibility by frequency lowering. The hearing aid system is configured to program the configurable signal processing unit of the hearing device according the claimed method. The invention may e.g. be used in hearing aids.
