Abstract: Hearing aid system comprising at least one hearing aid is provided. The hearing aid system further 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 processing unit connected to said input unit and to said output unit and comprising signal processing parameters to provide said processed versions of said at least one electric input signal, at least one photoplethysmogram (PPG) sensor configured to provide a PPG signal of the hearing aid user, and a listening effort determination unit configured to provide at least one PPG morphology parameter value based at least on the PPG signal, compare the at least one PPG morphology parameter value with at least one corresponding reference PPG morphology parameter value and determine a morphology comparison measure, and determine a listening effort of the hearing aid user. A hearing aid is further provided.

Abstract: A bearing aid is configured to be located at or in an ear of a user. The hearing aid comprises a heartbeat detector providing a pulse control signal, and a processor. The processor is configured to estimate whether the hearing aid is located at a left or a right ear of the user in dependence of the pulse control signal. A method of operating a bearing aid and a binaural hearing aid system is further disclosed.

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).
