A hearing aid having one or more biometrical sensors, where the hearing aid comprises at least one microphone configured to receive a sound of the surroundings, a signal processor configured to process the sound received from the microphone and a speaker unit configuration configured to emit the processed sound into the ear of a user, wherein one or more sensors is positioned substantially in the ear together with at least a part of the hearing aid, wherein the one or more sensors is configured as biometrical sensors configured for recording health data of a hearing aid user.

Hearing aid comprising one or more sensors for biometrical measurements

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.

Hearing aid comprising a physiological sensor

An electrooculography (EOG) signal capture system comprises a) a sensor array adapted for being located at one of a left or right ears of a user and/or for fully or partially being implanted in the head at left or right ears of a user, the sensor array comprising a number Ns of electric potential sensors, respectively, for sensing respective electric potentials from the user's head, where Ns is larger than or equal to two, b) electronic circuitry coupled to the sensor array and configured to provide at least two different beamformed signals (S, S), each being representative of a weighted combination of said electric potentials, or of signals derived therefrom, and wherein a difference between said at least two different beamformed signals (ΔP=S−S)—at least in a specific electrooculography mode of operation—represents an electrooculography signal (ΔP) from one or both eyes of said user. A single-sensor EOG-system is further proposed. The invention may e.g. be used in hearing aids or other electronic wearables.

System for capturing electrooculography signals

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.

Hearing aid determining listening effort

A hearing 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 hearing aid and a binaural hearing aid system is further disclosed.

Hearing aid comprising a left-right location detector

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 () is adapted to pick up a low voltage electric signal from the user's skin. The sensor arrangement further comprises a light sensor () located at a surface of said housing to allow emitting light through skin proximate to the light sensor () 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 () that is connected to the surface electrode () and the light sensor () and that is configured to generate one or more sensor signals from each respective output signal of the at least one surface electrode () and the light sensor (). The hearing aid system further comprises or is connected to an evaluation unit () that is configured to generate an electrocardiogram-representing signal (ECG) from low voltage electric signals picked-up by the at least one surface electrode () and a plethysmographic-curve-representing signal from an output signal of the light sensor ().
