    Abstract: The present application relates to a system comprising a hearing aid, the hearing aid configured to be operated based on an estimation of a current listening effort of a hearing aid user. The system comprising an input unit for receiving an input sound signal from an environment of the hearing aid user and providing at least one electric input signal representing said input sound signal, an output unit for providing at least one set of stimuli perceivable as sound to the hearing aid user based on processed versions of said at least one electric input signal, a signal-to-noise ratio (SNR) estimator for determining an SNR in the environment of the hearing aid user, a processing unit connected to said input unit and to said output unit and comprising signal processing parameters of the system to provide processed versions of said at least one electric input signal, a memory unit configured to store reference sets of SNR and pulse transition time (PTT) of the hearing aid user, at least a first and a second physiological sensor, wherein the system being configured to determine, based on the first physiological sensor, a first point in time at a first maximum upslope point of a first measured parameter, determine, based on the second physiological sensor, a second point in time at a second maximum upslope point of a second measured parameter, establish a current PTT by calculating a time difference between the first point in time and the second point in time, and determine, based on the current PTT and the stored reference sets of SNR and PTT, a current listening effort of the hearing aid user.

    Abstract: The invention concerns a hearing aid system that comprises an ear canal member comprising a sensor arrangement. The sensor arrangement comprises at least one surface electrode located at a surface of said ear canal member to allow said at least one surface electrode to contact the skin of a user when said ear canal member is operationally mounted on the user. The at least one surface electrode (150) is adapted to pick up a low voltage electric signal from the user's skin. The sensor arrangement further comprises a light sensor (180) located at a surface of said housing to allow emitting light through skin proximate to the light sensor (180) and capturing reflected and/or scattered light when said ear canal member is operationally mounted on the user.
    The hearing aid system further comprises a sensor signal processing unit (170) that is connected to the surface electrode (150) and the light sensor (180) and that is configured to generate one or more sensor signals from each respective output signal of the at least one surface electrode (150) and the light sensor (180).
    The hearing aid system further comprises or is connected to an evaluation unit (300) that is configured to generate an electrocardiogram-representing signal (ECG) from low voltage electric signals picked-up by the at least one surface electrode (150) and a plethysmographic-curve-representing signal from an output signal of the light sensor (180).
