    摘要： 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.

The application further relates to a method of operating a binaural hearing assistance system. The object of the present application is to provide an improved binaural hearing assistance system. The problem is solved in that the system further comprises d) a comparison and calculation unit for comparing said electric input signals, and/or said separated sound source signals X s l , X s r and/or said localization parameters LP s l , LP s r of said left and right hearing assistance devices, respectively, to estimate a head related transfer function HRTF value for one or more of said sound sources S with said localization parameters LP s at a given point in time; and e) a memory unit for storing and updating a database of said HRTF values and optionally said localization parameters LP s over time. This has the advantage of providing a flexible binaural hearing assistance system that is capable of learning the relevant HRTFs of its user, optionally without being initialized. The invention may e.g. be used in hearing aids, headsets, ear phones, active ear protection systems and combinations thereof.

    摘要： The present invention relates to methods and apparatus for processing audio signals. It is based on the discovery that varying the FM index of fast FM modulations of a sound affects the spectral content of the sound in a way that a listener directly interprets as varying the apparent loudness of the sound, and as varying the vocal effort in the case that the sound is speech.
    The invention covers a method for processing an audio signal (i(t)), the method comprising: receiving a first set (x(t)) of time-varying signals representing a first sound comprised in the audio signal (i(t)), the first set (x(t)) of time-varying signals comprising an amplitude modulation signal (a(t)), a carrier frequency signal (f c (t)), a pitch signal (f 0 (t)) and an FM index signal (h(t)); and modifying the first set (x(t)) of time-varying signals by modifying the amplitude of the FM index signal (h(t)), thereby providing a first modified set (x'(t)) of time-varying signals.
    The resulting first modified set (x'(t)) of time-varying signals may subsequently be modulated to provide an audio output signal. The invention may be useful in a wide range of audio processing systems, e.g. audio broadcast systems, audio communication systems, speech recognition systems, audio reconstruction systems and public address systems as well as in audio processing apparatus, such as hearing devices.
