摘要： A method of programming a configurable signal processing unit of a hearing aid device comprises
• Providing a frequency transposition algorithm in the hearing aid device where content from more than one upper-lying source frequency band is copied or moved into one and the same lower lying destination frequency band;
• Providing a number of frequency transposition configurations, each comprising a specific combination of source regions and a destination region;
• Providing a weight parameter that specifies the amount of gain applied to a lowered signal resulting from a given frequency transposition configuration; and
• Providing a prescription algorithm that selects an optimum frequency transposition configuration for an ear of a user taking an audiogram for the ear in question and an amplification capability of the hearing aid device in question into account.
A purpose of the disclosure is to provide an improved audibility of high frequency sound for users with severe-to-profound hearing losses.

摘要： A hearing device adapted for being worn at or in an ear of a user, comprises a) an input unit comprising at last two input transducers each for converting sound around said hearing device to an electric input signal representing said sound, thereby providing at least two electric input signals; b) a beamformer filter comprising a minimum processing beamformer defined by optimized beamformer weights, the beamformer filter being configured to provide a filtered signal in dependence of said at least two electric input signals and said optimized beamformer weights; c) a reference signal representing sound around said hearing device; d) a performance criterion for said minimum processing beamformer. The minimum processing beamformer is a beamformer that provides the filtered signal with as little modification as possible in terms of a selected distance measure compared to said reference signal, while still fulfilling said performance criterion. The optimized beamformer weights are adaptively determined in dependence of said at least two electric input signals, said reference signal, said distance measure, and said performance criterion. A method of operating a hearing device is further disclosed. The invention may e.g. be used in hearing aids or headsets.

摘要： A signal processing method and a hearing device for isolating a user's own voice from microphone signals is disclosed. The signal processing method comprises the following steps. Providing at least two microphones at one ear of a user or at least one microphone at each ear of the user. Receiving sound signals by the microphones. Isolating a user's own voice from the microphone signals by way of a combination of at least two of the following processes: a) applying own voice detectors to the microphone signals, b) using monaural and binaural directional microphone systems, c) using monaural and binaural directional microphone systems with near field emphasis, and d) applying speaker identification models to the microphone signals. Estimating a stress level or cognitive load from the isolated voice. Adjusting settings of a device in dependence of the estimated stress level or cognitive load.

摘要： Ahearing device, e.g. a hearing aid, comprises
• an input unit for providing at least one electric input signal representing sound in a frequency sub-band representation (k, m), where k and m are frequency and time indices, respectively,
• an SNR estimation unit for estimating a signal to noise ratio and/or a level estimation unit for estimating a level of said at least one electric input signal, or a signal or signals derived therefrom, in said frequency sub-band representation,
• and a configurable frequency transposition unit for transposing content of a source frequency sub-band FB S into a destination frequency sub-band FB D so that the contents of the resulting destination frequency sub-band is determined as a weighted combination of the contents of the source and destination frequency sub-bands according to the expression P Dmod = αP D + βP S or MAG Dmod = αMAG D + βMAG S wherein P D and MAG D are the unmodified power spectrum and magnitude, respectively, of the destination frequency sub-band before frequency transposition, P S and MAG S are the power spectrum and magnitude, respectively, of the source frequency sub-band, and P Dmod and MAG Dmod are the resulting power spectrum and magnitude, respectively, in the resulting destination sub-band after the frequency transposition, and the parameters α and β are destination and source band weight factors, respectively, that specify details of the frequency transposition operation. The configurable frequency transposition unit is configured to determine at least one of said weight factors α and β in dependence of said estimate of signal to noise ratio and/or said estimate of level of said at least one electric input signal or a signal or signals derived therefrom. A method of operating a hearing device is further disclosed.
