Abstract: 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.

Abstract: The invention relates to a method for operating a rotational molding apparatus that comprises a rotatably mounted rotational-molding mold holder having a rotational-molding mold. The method is characterised in that a trajectory of a reference point of a component for a rotation process, in particular a component of the rotational-molding mold holder or the rotational-molding mold, which component rotates during a rotation process, is selected from one of a plurality of possible trajectories that can be achieved by the rotational molding apparatus, and in that a rotation process is subsequently performed in which rotational-molding material introduced into the rotational-molding mold accumulates on the inner face of the rotational-molding mold and in which the reference point moves along the determined trajectory.

Abstract: A method operates a hearing device which performs active noise suppression for suppressing noise signals having one or more frequency components. An audiogram is provided which specifies a hearing threshold of a user of the hearing device as a function of frequency, wherein by using the audiogram it is determined which frequency components of the noise are audible to the user and which are not audible. The noise suppression is operated selectively by suppressing audible frequency components of the noise and by not suppressing inaudible frequency components of the noise. A corresponding hearing device is operated according to the method.

The hearing aid has a time measuring unit, which has a first timer and a second timer. The first timer is activated in the usage state and is deactivated in the idle state, for time measurement during the usage state. The second timer is activated in the idle state for time measurement during the idle state. Furthermore, a corresponding hearing aid is indicated.

Abstract: A method for operating a hearing device is specified. The hearing device is assigned to a user and connected to other hearing devices, which are each assigned to another user, for data exchange in a common network. The hearing device or one of the other hearing devices controls the data exchange by subscribing to the network as a master, and wherein all other hearing devices subscribe to the network as a slave. It is decided whether the hearing device subscribes to the network as a master or as a slave by determining the operational capability of the hearing device and comparing it with the operational capability of the other hearing devices and by the hearing device acting as a master if the hearing device has the highest operational capability, and otherwise as a slave.

Abstract: A method for operating a hearing aid which has a vent and the vent has a controllable closure for opening and closing the vent. The opening and closing of the vent is linked via a control rule to an environmental parameter, wherein the vent is controlled depending on the environmental parameter. The environmental parameter is ascertained and the vent is opened or closed in accordance with the control rule depending on the environmental parameter. The control rule is configured user-specifically. There are also described a corresponding hearing aid and a computer program product.

Abstract: A method operates a hearing device in present surroundings such that noise cancellation of the hearing device is activated, so that ambient sounds are reduced for a user of the hearing device. A desired value for the voice volume of the user is determined for the present surroundings. An actual value for the voice volume of the user is measured. If the actual value is lower than the desired value, the hearing device takes a measure to prompt the user to speak more loudly. Additionally, a hearing device is configured to implement the method.

Abstract: A method for operating a hearing device is specified. The hearing device has at least one microphone that picks up an input sound signal and converts it into an electrical input signal. The hearing device has a signal processing section that modifies the electrical input signal on the basis of an audiogram of a user and thereby generates a first electrical output signal.

Abstract: A connector for a hearing instrument, in particular a receiver-in-canal behind-the-ear hearing aid, is small and visually inconspicuous. The connector should be as invisible as possible on the hearing instrument as it is worn, and the connector allows a microphone arrangement favorable for directionality and sound pick-up. The connector is disposed on an earpiece tube, which defines a longitudinal direction at the connector. The connector is connected by insertion into a connector receptacle of a hearing instrument transversely to the longitudinal direction. The hearing instrument has a laterally arranged connector receptacle, into which a connector is inserted transversely to the longitudinal direction. Because of the transverse insertion, the connector can be arranged laterally on the housing and because of the lateral placement, the front end face of the housing is smaller and the housing is overall flatter.
