Abstract

See full text

A hearing device system has a photoplethysmography sensor to be worn in the auditory canal in an intended worn state and an earpiece which at least partly covers the photoplethysmography sensor toward the auditory canal in the intended worn state. Moreover, the hearing device system has a controller which is configured to use light captured by the photoplethysmography sensor to derive a comparison quantity of the earpiece characteristic for a transmission of the earpiece, for a wavelength range of the photoplethysmography sensor, to compare the comparison quantity with a specified first limit and to output an alert if the limit is traversed by the comparison quantity.
