Communication system for establishing and providing preferred audio
09747367 · 2017-08-29 · ·

An audio customization system responsive to one or more audio profiles to define a transformation to apply to audio information. The system allows users to select the profiles that dictate the nature of the customization of the audio delivered to an audio output devise such as a headphones. The system is set up to be able to lessen the influence of undesirable audio and enhance desirable audio. The system may specify aspects of audio to be modified by specification of filtering algorithm, characterization of audio samples, monitored distortion, user selection, location specification or environmental specification and may be used in a social networking system.

A method (300) of operating a hearing aid system (100), wherein the dynamic range of input signal levels is improved by reducing the sensitivity of an input transducer in response to a trigger event while at the same time applying a gain adapted to compensate the reduced sensitivity and a hearing aid system (100, 200) adapted to carry out the method.

Method, device and system for increasing a person's ability to suppress non-wanted auditory percepts

The present disclosure relates to a method for reducing a listener's task-irrelevant auditory perception, the method comprising providing a measuring device or system configured for measuring the listener's alpha, beta gamma and/or theta activity and providing a generation device or system configured for generating an alpha, beta, gamma and/or theta activity boosting signal that, when provided to the listener will increase the listener's ongoing alpha, beta, gamma and/or theta activity. The listener's alpha, beta, gamma and/or theta activity is measured and if the measured alpha, beta, gamma and/or theta activity is below a predefined threshold, the listener's ongoing alpha, beta, gamma and/or theta activity is increased by the provision of the alpha, beta, gamma and/or theta activity boosting signal to the listener. This results in the listener's ongoing alpha, beta, gamma and/or theta activity being increased, resulting in facilitating reduction of task-irrelevant auditory perception, such as the auditory perception of noise or tinnitus, and thereby also increasing the listener's ability to understand speech under adverse listening conditions. The present disclosure further suggests using the listener's measured alpha, beta, gamma and/or theta activity to judge if the listener is ready to understand speech, and if this is not the case to delay a speech signal until a sufficiently high activity is present.
