A method for personalized sound modification, with a personal sound system having a microphone; a user device which includes a processor, computer readable medium, and optionally the microphone; and a sound output device; is provided. The method includes: providing a user hearing profile including lower and upper limits of the user's auditory dynamic range at a plurality of sound frequencies, prepared with the personal sound system; receiving a sound signal from the microphone; optionally separating the sound signal into a plurality of frequency channels; amplifying or attenuating sound frequencies in the sound signal which have a volume level outside the lower or upper limits of the user's auditory dynamic range, respectively, and forming a modified sound signal with which the sound output device will produce sounds within the user's auditory dynamic range; and providing the modified sound signal to the sound output device.

A hearing device includes a processor and a wireless transceiver operatively connected with the processor and configured to connect via a wireless link with a remote device and to exchange bi-directional audio packets with the remote device. The processor is configured to monitor an audio link quality and adapt a transmit power of the hearing device as a function of the audio link quality.

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.

A method includes: initializing signal-processing parameters of the hearing aid at different frequencies based on attribute data and hearing characteristic data of a user, wherein the signal-processing parameters comprising a gain; processing a hearing test signal to be played based on initialized values of the gain, and obtaining a processed hearing test signal; playing the processed hearing test signal and determining a hearing test result of the user using the hearing aid; and in a case where the hearing test result indicates that the hearing aid does not meet a preset first hear-aiding requirement, adjusting values of the gain of the hearing aid at different frequencies based on the hearing test result, and continuously iterating a hearing test based on the adjusted values of the gain until the hearing aid meets the preset first hear-aiding requirement. A hearing aid is also provided.
