A method and a device are provided for modifying audio signals in accordance with hearing capabilities of an individual who is listening to audio signals played by a music player. The method comprises the steps of: providing a music player operative to play audio signals, wherein the music player comprises a processor configured to modify audio signals that are about to be played, by taking into account the hearing capabilities of the individual; providing information that relates to the hearing capabilities of the individual; forwarding the information that relates to the hearing capabilities of the individual, from an electronic device to the music player; and using the music player processor to modify audio signals when the individual is listening to audio signals being played by the music player, wherein the audio signals are modified before they are played by taking into account the individual's hearing capabilities.

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 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 signal processing device, comprising a high band attenuation filter which attenuates a signal component in a bandwidth of frequency higher than at least a predetermined frequency in an audio signal that is input, and a hearing aid processor which performs hearing aid processing on a signal output from the high band attenuation filter, wherein the predetermined frequency is determined according to the upper limit of a target bandwidth of frequency for hearing aid.

A system and method for is provided for operation of an orthopedic system. The system includes a load sensor for converting an applied pressure associated with a force load on an anatomical joint, and an inertial sensing device configured to measure alignment. The inertial sensing device provides alignment measurement data to measure alignment. An ultrasonic transducer, MEMs microphone, electromagnets, optical elements, metallic objects or other transducers can be configured to convert or convey a physical movement to an electrical signal and support measurement of muscular-skeletal alignment. The load sensor can be used to measure load magnitude and position of load of an applied load by the muscular-skeletal system.

The present invention relates to a receiver unit comprising a plurality of moveable membranes, a motor assembly being adapted to drive a first moveable membrane and one or more successive moveable membranes in accordance with an incoming electrical drive signal, wherein the first and at least one of the successive moveable membranes have different frequency responses in order to enhance the frequency response of the receiver unit. The present invention further relates to a hearing aid instrument comprising the receiver unit.
