A power-saving control of the receiver in hearing devices with wireless transmission to other devices is also to be possible without significant interferences. Provision is thus made in accordance with the invention for a hearing apparatus, in particular a hearing device, with a transmission facility for wireless data transmission in a main frequency band, a loudspeaker and a control facility for controlling the loudspeaker with a control signal, with the frequency spectrum of the control signal having a significant notch in the range of the main frequency band. A 'noise-shaping' of this type can be achieved by pulse-density modulated receiver control signals.

Hearing apparatus with low-interference receiver control and corresponding method

For reducing the influence of interference fields on hearing aids, a hearing aid is provided with an electronic component into which a first and a second electromagnetic disturbance component can be injected by providing a predetermined electromagnetic interference field. The electrical component is formed asymmetric and/or a compensation component is arranged on the electrical component such that the first and the second interference components largely compensate for one another. A compensation plate or an element which is provided in any case, such as a microphone, may be used as the compensation component. If the electrical component is a coil, then its core may, for example, be conical or configured such that its winding density varies.

Hearing apparatuses with transmission facilities for the wireless transmission are to be miniaturized further. A transmission facility for a hearing apparatus and in particular a hearing device with an oscillating circuit including a capacitor and a coil as well as an electrical line is provided in or to the oscillating circuit, with the electrical line having a shielding. The electrical line includes a film conductor with a signal line and shielding line, the shielding capacitance of which is connected in parallel to the capacitor of the oscillating circuit. The shielding capacitance can be used together with the capacitance of the capacitor in a targeted fashion as an oscillating circuit capacitance. In this way, the parasitic shielding capacitance is used as a wanted capacitance. As the shielding capacitance of the film conductor is only subjected to minimal fluctuations, it only requires a small tuning capacitor for tuning the oscillating circuit.

The invention relates to a receiver system for an otological device. The receiver system has an oscillation receiver to receive a carrier signal with a carrier frequency. The receiver system is designed to change a receive frequency for the carrier signal. The receiver system has a frequency regulator which is designed to at least indirectly register the receive frequency and to change the receive frequency for the carrier signal to a predetermined receive frequency and to set it to the predetermined receive frequency. The frequency regulator is connected to the oscillation receiver at least at least indirectly and is designed to generate an excitation signal and to excite the oscillation receiver to oscillate by means of the excitation signal and thus to generate a response oscillation with a response frequency. The frequency regulator is also designed to ascertain the receive frequency depending on the response oscillation.

A hearing apparatus with an external receiver is to be made even smaller. Provision is accordingly made for a hearing apparatus with a housing and a receiver device that is removably electrically coupled to the housing, said receiver device having an electronic identification element and having a receiver that is connected to an electrical cable with a sheath cable, with the sheath cable and the electronic identification element being conducted into the housing via a common single-pole connection. As a result of the multiple usage of the single-pole connection for shielding and identification, the female connector of the hearing device and the plug of the receiver device can be made smaller.

The invention relates to a multi-component hearing aid system, comprising at least one first component that is designed to be disposed on or in the ear of a patient for the purpose of generating and/or amplifying an auditory stimulus and at least one further component which can engage at least partially and/or temporarily in a wireless communication connection via which a data transmission can take place with the first component that is to be worn on or in the ear, wherein circuitry means are included which can place at least one source of interference contained in the hearing aid system at least during the transmission of data into an operating mode in which interference signals are coupled by said at least one source of interference into a receiver involved in the data transmission in a manner that is at least attenuated compared to the normal operating mode.

Multi-component hearing aid system and a method for its operation

The aim is for an LC oscillator circuit of a hearing apparatus to be operated on a sustained basis in a desired frequency range. To this end, a hearing apparatus is proposed having an oscillator and a trimming facility for trimming the oscillation frequency of the oscillator. A control facility controls the oscillation frequency of the oscillator with the aid of the trimming facility in accordance with a predetermined desired value. An automatic self-trimming of a wireless transmission system in a hearing apparatus and in particular in a hearing device is thus possible.

Hearing apparatus with automatic self trimming and corresponding method

Data is wirelessly transferred between a hearing aid and an external device, wherein the hearing aid via an internal receiving device, receives data being sent form the external device via a wireless connection. The hearing aid is in a receiving mode when data from the external device is sent via the wireless connection, wherein the receiving device is then permanently in the on-position for receiving data. Furthermore, the hearing aid switches to a stand-by mode, when no data is sent via the wireless connection from the external device, wherein the receiving device is alternatively turned on and off, in order to detect a beginning data transfer from the external device.

Method for wireless data transfer between a hearing aid and an external device

A method for identifying hearing aids is described wherein a wireless connection is established between a control device and at least one unidentified hearing aid, and which comprises the following procedural steps: a request is sent by the control device to at least one unidentified hearing aid; the request is received by the hearing aid addressed; a response is provided in the hearing aid addressed, whereby the response contains an individual identifier of the respective hearing aid; and the response is sent by the hearing aid addressed to the control device, whereby the response is transmitted at a point in time that is individually determined by the responding hearing aid.

Method for identifying hearing aids within the scope of wireless programming

A hearing device, in particular a hearing aid, occupies a small volume and has high data transmission speeds for wireless transmission. In order to avoid using large volume frequency-stable components, for this purpose, an oscillator unit with a free-running oscillator is used instead. A receiver receives a synchronization signal cyclically. This is correlated to a reference signal in a correlator, such that the arrival time of the synchronization signal can be defined exactly. The free-running oscillator is then retuned correspondingly.

Hearing device without reference clock component

The operation of appliances in a home network is to be made more user-friendly, for which purpose provision is made for the hearing device remote control unit to be integrated as a component in a network. This would, for example, enable warning signals triggered by the network to be provided in the hearing devices.

Hearing device remote control unit as a network component and corresponding use thereof

In a hearing aid device system with two hearing aids for binaural supply to a hearing aid user, a coupling of the settings of both hearing aids is not always reasonable in the 'audio reception' mode and therefore the hearing aid that is in the 'audio reception' operating mode is not adapted to changed settings when parameters in the other hearing aid of the hearing aid system have been readjusted. The use of a remote control also has different effects on a hearing aid in the active &#x201c;audio reception&#x201d; mode than on the hearing aid device that is in a passive &#x201c;audio reception&#x201d; mode.

Hearing aid system and operating method therefor in the audio reception mode

The communication device in a hearing aid needs to be optimized with respect to spatial requirements and power consumption. To this end, provision is made for an inductor in an oscillator circuit to be used simultaneously as an antenna. Besides reducing the number of components, this also reduces the power consumption. Further optimization in terms of energy can be achieved by virtue of a comparator being used to actuate a controllable current source such that energy is fed into the oscillator circuit only during a half-cycle.

Data transmission device for hearing aids

An energy-saving communication is made available in a hearing aid system. For this purpose the individual communication participants are given different priorities, by using data packets of variable length in the communication. The longer data packets of higher priority prevail when the transmission requests of lower priority are paused as long as the communication channel is busy. In this manner a suitable communication can be structured in a hearing aid system comprising, for example, of two hearing aids and a remote control.
