摘要:
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.

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.

A hearing aid configuration and an associated method provide wireless transmission of data between a hearing aid and an external unit. The external unit, for example a programming device, is worn with a lanyard around the neck of a hearing aid user. The configuration additionally contains at least one second antenna disposed in the lanyard and at least one third antenna arranged in the lanyard which is connected by an electric series circuit to the second antenna. The advantage of this is that the lanyard can be made long enough to be comfortable to wear and a sufficiently high receive signal of the wireless data transmission is still guaranteed in the external unit.

The influence of interference from power supply lines in hearing devices is to be reduced. Thus a hearing device with an antenna for receiving and/or sending inductive signals, a signal processing device, to which the antenna is connected, a power supply unit for supplying power to the signal processing device and an electrical conductor for electrical connection of the power supply unit to the signal processing device is provided. The electrical conductor is L-shaped or U-shaped and closely follows the contours of the power supply unit. In addition the electrical conductor forms a part of an essentially round or rectangular ring, the axis of which has a main directional component perpendicular to the longitudinal axis of the antenna. A magnetic field created by the conductor is thus perpendicular to the antenna, so that its magnetic interference influence is reduced.

Wireless communication is to be enabled between hearing units of small construction, especially between hearing aids with an increased data rate. To this end it is provided in accordance with the invention that the hearing unit is fitted with a transceiver which has an inductive receiving device and a digital wideband pulse transmitter. Two such hearing units can then communicate wirelessly with one another with the help of a communication station which is structurally separate from the hearing units and with which a message can be transmitted from the one to the other of the hearing units. The digital wideband pulse transmitter can be implemented in a structurally small manner in the hearing unit and with low power consumption.

A method and appertaining system implement the use of manufacturing protocols for hearing aid design such that the ability to build an instrument can be displayed as a numeric parameter based on the partial numerical and metrological contributions of all the essential parameters of the given impression, and a buildability index can be displayed as a 3D virtual image of the proposed shell or preferred shell types. The method utilizes a predefined parameter table comprising parameters to utilize for a buildability determination. The buildability index is computed based on impression shape data, selected shell type, selected number of device options, data obtained from the parameter table, and data obtained from a receiver table, and the buildability index is output to a display of a user interface device or an external system.

A one-piece in-the-ear hearing device housing and a method for producing the in-the-ear housing are provided. The housing is mechanically separable into at least one faceplate and a housing shell. In one aspect, the hearing device housing has an interlayer between the faceplate and the housing shell. Different shrinking of the housing shell and faceplate is avoided in the production.
