Abstract: A hearing aid has an interchangeable earpiece, which, on its own and separately from further components, can be replaced in a simple fashion and without great complexity, and without specialist tools. The hearing aid has a housing of a multi-part design and a receiver and a signal processing device within the housing. The receiver is arranged detachably in a first housing part and the signal processing device is disposed in a further housing part and the two housing parts are detachably interconnected. A detachable locking mechanism connects the housing parts. The receiver is connected to the signal processing device by way of a detachable electrical connector with a receiver-side and a signal-processing-device-side electrical contact. At least one of the electrical contacts is elastic.

Abstract: In an embodiment, a hearing aid housing is provided. The hearing aid housing may include a first behind-the-ear hearing aid housing portion, a second behind-the-ear hearing aid housing portion, and a moisture protector at least partially arranged between the first behind-the-ear hearing aid housing portion and the second behind-the-ear hearing aid housing portion.

Abstract: With a hearing aid device in a frame configuration, acoustic feedback is avoided with an opened battery charger. To this end, a seal surrounds the frame component in an annular manner, the seal sealing a gap between the frame component and the housing thus providing a more user friendly hearing aid.

Abstract: A hearing aid retains speech comprehension even during implementation of a frequency transposition. To this end, fricatives existing in an input signal prior to the frequency transposition are identified in particular with the aid of the energy distribution between the individual frequency bands. Following the frequency transposition, amplifier units are controlled in the transposed frequency bands such that a specific energy distribution existing in the non-transposed frequency bands between at least one first upper frequency band and a first lower frequency band is mapped onto a corresponding energy distribution between a second upper frequency band and a second lower frequency band of the frequency-transposed signal. This results in the fricatives obtained in the original input signal also being correctly identified following a frequency transposition.

Abstract: A hearing aid can be inserted deep inside an auditory canal without the risk of injury. The hearing system has a hearing device that can be completely inserted into a human auditory canal, and a positioning device, which is attached to the hearing device in a self-retaining manner. The positioning device can be detached from the hearing device, when the latter is in the state where it is inserted into the auditory canal, and cannot or can only partly be inserted into the auditory canal because it serves as a stop on a section of the concha when the hearing device is being positioned. The positioning device is decoupled from the hearing device after placement and removed from the auditory canal.

Abstract: In an embodiment, a hearing aid is provided. The hearing aid may include a behind-the-ear component, a sound tube coupled with the behind-the-ear component at its one end, and a loudspeaker coupled with the sound tube at the other end of the sound tube opposite to the behind-the-ear component. The hearing aid may further include a joint connected between the loud-speaker and the sound tube, wherein the joint is moveable or flexible such that a degree of freedom in movement is provided in a direction substantially perpendicular to an insertion direction of the loudspeaker into an ear canal.

Abstract: A method operates a hearing apparatus. The hearing apparatus contains a frequency separating filter characterized by a threshold frequency, which splits an input signal into a low-frequency signal component and a high-frequency signal component. The hearing apparatus further has a first device, which can be used to set the threshold frequency of the frequency separating filter so that artifacts in an output signal of the hearing apparatus are reduced.

Abstract: An in-the-ear hearing instrument has a programming connector arranged in a faceplate and at least one microphone opening arranged in the faceplate. The programming connector is covered by an openable cover, and the at least one microphone opening is at least partially covered by at least one lining. The cover and at least one lining are integrated into a shared cover and lining device which at least partially covers both the programming connector and also the at least one microphone opening in a manner so as to be openable.

Abstract: 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.

Abstract: Feedback in a hearing device and, more particularly, in a hearing aid should be compensated for before it becomes audible. To this end, a method is proposed for compensating for a feedback signal in a hearing device with an input-transducer apparatus, a signal-processing apparatus and an output-transducer apparatus, in which method a feedback signal is compensated for, which feedback signal is fed back to the input-transducer apparatus from the output-transducer apparatus or the signal-processing apparatus. More particularly, a probability of having a plurality of notches, equally spaced apart from one another, in the spectrum of an input signal is established, which input signal originates directly from the input-transducer apparatus or which is a difference signal between the signal directly from the input-transducer apparatus and a compensation signal serving for compensation. The compensation is modified or the signal-processing apparatus is amplified as a function of this established probability.

Abstract: For particularly good adaptation to a given hearing situation, an in-the-ear hearing device which has a housing with a channel in the housing that is designed as a through-opening for sound and air between the interior of the ear and the environment outside the ear, the channel is provided with a structural element for changing the size of the through-opening at at least one position. The structural element is a valve formed with electroactive material and the size of the through-opening is adjusted by application of a voltage to the valve.

Abstract: It is desirable for the production of workpieces, which are sometimes produced by a rapid prototyping method, to be further automatable. To this end a device is provided having a laser for generating a laser beam in order to set a material, and a workpiece support which can be exposed directly to the laser. There is also provided an optical instrument for redirecting and deviating the laser beam so that the workpiece support can also be exposed indirectly to the laser. Material can therefore also be cured more easily in undercuts of workpiece blanks.

Abstract: A circuit for operating a hearing device with a variable operating parameter is disclosed. A storage device for storing operating parameter settings in a starting situation as well as in a target situation and a control unit, which implements a matching of the operating parameter according to a setting of the starting situation to the operating parameter settings of the target situation, is provided. Further, a connection device for connection to a control element and a data processing device for influencing the operating parameter by a user of the hearing device, is provided. The control unit performs the matching of the operating parameter with a minimal matching rate in time segments in which the operating parameter is often influenced by the control element or data processing device, and with a higher matching rate in time segments, in which the operating parameter is rarely influenced or not influenced at all by the control element or data processing device.

Abstract: 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.

Abstract: Systems and methods are provided for customizing a hearing aid casing. A user accesses a software program that allows him or her to select a type of a hearing aid. The software program further allows the user to select a motif to be displayed on at least a portion of the hearing aid casing. The software program may automatically size the selected motif based on the type of the hearing aid selected, and the selected motif may be printed on a film. The film then is coupled to the hearing aid casing to display the motif on one or more surfaces of the hearing aid casing.

Abstract: A hearing aid with wireless signal transmission is provided which includes a radio reception unit for wireless reception of modulated and/or coded audio signals, a device to estimate the reception quality of the received audio signal, a device to generate an acoustic limit signal whose level increases when the estimated reception quality of the received audio signal decreases, a device to heterodyne a demodulated and/or decoded audio signal with the limit signal, and a device to output the audio signal heterodyned with the limit signal to a hearing aid wearer. To generate a limit signal, the hearing aid includes a device to generate an impulse response and a device to perform the operation of convolving the demodulated and/or decoded audio signal with the impulse response. This convolution produces a desired signal which appears closer to the hearing aid wearer when the estimated reception quality is better.

Abstract: A hearing apparatus has a housing, a receiver in the housing, and a sound conductor through which sound from the receiver is conducted out of the housing. In order to render the device as small as possible, the hearing apparatus has a cover piece which is inserted into the housing in such a way that a sound channel is formed. The sound channel is thereby delimited at the sides by the housing and the cover piece. A special sound-conducting tube can therefore be dispensed with.

Abstract: A microphone system and an associated method are proposed. The microphone system comprises at least two omnidirectional, microphone signal-emitting directional microphones connected electrically to one another to establish directivity, at least one filter unit with at least one adaptation parameter for the adaptive filtering of the at least two microphone signals and a control unit to change the at least one adaptation parameter such that the sum of interference power is reduced. The value range of the at least one adaptation parameter is limited. The control unit determines limits from a comparison of the noise floor of the ambient noise with a microphone noise number. The adaptation range of an adaptive differential directional microphone is a function of stationary component of background noise, so the directivity can be selected such that the non-stationary microphone noise resulting due to directivity is masked by the stationary component of the background noise.
