Abstract: A hearing device configured to be worn by a user comprises one or more microphones, a processing unit, a speaker, a wireless communication unit, and stress evaluator. The user wearing the hearing device is in an environment defined by an acoustic scene. The microphones receive audio signals from audio sources in the environment and provide them to the processing unit which applies processing parameters to thereby process the audio signals. The speaker provides the processed audio signals to the user. The stress evaluator generates an indication of stress of the user, stress of the user being related to the acoustic scene. The processing unit then decides whether to perform an action on the basis of the received audio signals and the indication of stress of the user.

Abstract: A hearing aid system may include an ear-mould for a child, an output transducer, and an electrical feedback path. A forward path includes a signal processor that modifies an electrical input signal to a specific hearing profile over a predefined frequency range which includes a number of frequency bands. Maximum forward gain values IGmax for each band are stored in a memory, restricting loop gain to a predetermined value in each band. The hearing aid system further includes a relatively slow online feedback manager unit configured to, with a predefined update frequency, identify current feedback gain in each frequency band, and to subsequently adapt the maximum forward gain values IGmax in each of the frequency bands in accordance with a predefined scheme. The feedback manager unit is thus reduces the risk of howling by decreasing the maximum forward gain values IGmax in said ear-mould for a child.

Abstract: The invention relates to a method of identifying and correcting errors in a noisy binary mask. An object of the present invention is to provide a scheme for improving a binary mask representing speech. The problem is solved in that the method comprises a) providing a noisy binary mask comprising a binary representation of the power density of an acoustic signal comprising a target signal and a noise signal at a predefined number of discrete frequencies and a number of discrete time instances; b) providing a statistical model of a clean binary mask representing the power density of the target signal; and c) using the statistical model to detect and correct errors in the noisy binary mask. This has the advantage of providing an alternative and relatively simple way of improving an estimate of a binary mask representing a speech signal. The invention may e.g. be used for speech processing, e.g. in a hearing instrument.
