    Abstract: A method for processing an audio signal (i(t)), comprises: 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 (fc(t)), a pitch signal (f0(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.

    Abstract: The present invention regards an in-ear stimulation device comprising at least one in-ear sensor, a control unit, and an output transducer. The in-ear stimulation device is configured to be worn at or on an ear of a human user and at least partly in an ear canal of the user. The at least one in-ear sensor is arranged and configured to measure electrical activity signals indicative of an electroencephalogram (EEG) of a user wearing the device. The control unit is configured to receive the electrical activity signals and to detect a presence of a slow oscillation, which is in a frequency range between 0.5 Hz and 1 Hz, in the electrical activity signals. The control unit is further configured to trigger, in response to detecting the presence of a slow oscillation, a generation of at least one stimulus impulse. The output transducer is configured to receive the at least one stimulus impulse and to generate a corresponding output sound.

    Abstract: A listening device processes an electric input sound signal and provides an output stimulus perceivable to a wearer of the listening device as sound, the listening device comprising a signal processing unit for processing an information signal originating from the electric input sound signal and to provide a processed output signal forming the basis for generating said output stimulus. A perception unit establishes a perception measure indicative of the wearer's present ability to perceive said information signal. A signal interface communicates the perception measure to another person or device.
