Abstract:
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.
Abstract:
The application relates to a hearing assistance system comprising first and second spatially separated parts adapted for being mounted fully or partially at a first ear and on the head of a user, respectively, the first and second parts comprising a number of first and second electrodes located at a surface of first and second housings, respectively, to allow said first and second electrodes to contact the skin of the user when said parts are operationally mounted on the user's head. The first and second electrodes are adapted to pick up low-voltage electric signals from the user's brain and a reference voltage, respectively, to provide voltage difference signals. An improved binaural hearing assistance system further comprising a comparison unit for determining the voltage difference signal, and an electric interface allowing the reference voltage or a measure representative thereof to be transferred from said second part to said comparison unit is provided.
Abstract:
A system for operating a hearing instrument is disclosed. The system comprises one or more electrodes for measuring the brain wave signals of a user wearing a hearing instrument. The electrodes are placed on the scalp of the user. Based on the measured brain wave signals, a detecting unit is configured to detect a relaxation state of the hearing instrument. A controller sets the hearing instrument to a relaxation mode setting in response to the detection of the relaxation state of the user.
