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.
