Abstract: A method for specifying design rules for a manufacturing process includes providing a training set of 3D point meshes that represent an anatomical structure, for each 3D point mesh, finding groupings of points that define clusters for each shape class of the anatomical structure, calculating a prototype for each shape class cluster, and associating one or more manufacturing design rules with each shape class prototype. The method includes providing a new 3D point mesh that represents an anatomical structure, calculating a correspondence function that maps the new 3D point mesh to a candidate shape class prototype by minimizing a cost function, calculating a transformation that aligns points in the new 3D point mesh with points in the candidate shape class prototype, and using the rules associated with the shape class prototype, if the candidate shape class prototype is successfully aligned with the new 3D point mesh.

Abstract: Hearing apparatuses and in particular hearing devices are to be designed to be smaller. To this end, provision is made for an assembly device for fastening a component in the housing of a hearing apparatus with a first arm for retaining the component and a second arm, which can be plugged at least partially into/onto a corresponding fastening element on the interior of the housing. A hinge connects the two arms in a pivotable fashion. After connecting the assembly device to the fastening element, the two arms are snapped onto one another by pivoting about the hinge and thus adopt a final assembly position. This retractable mechanism also allows the use of space below a cover segment of the housing.

Abstract: 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.

Abstract: 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.

Abstract: The data records to be stored in the two hearing devices of a binaural hearing system during the adjustment are generally different. With “side definition”, the correct assignment of the two hearing devices to the ears or of the wearer is ensured. To this end, an acoustic signal is transmitted to the wearer by way of the receiver of at least one of these hearing devices. The wearer informs the adjusting facility by way of an input device connected hereto, as to the ear with which the wearer heard this acoustic signal or which spatial characteristic or asymmetry is attributed to this acoustic signal.

Abstract: A method for operating a hearing aid in a hearing aid system where the hearing aid is continuously learnable for the particular user. A sound environment classification system is provided for tracking and defining sound environment classes relevant to the user. In an ongoing learning process, the classes are redefined based on new environments to which the hearing aid is subjected by the user.

Abstract: The invention relates to a method for operating a hearing aid. A local source operating mode is established by a signal processing section of the hearing aid for tracking and selecting a local acoustic source of an ambient sound. Electrical acoustic signals from which the local acoustic source is determined by the signal processing section are generated by the hearing aid from the detected ambient sound. The local acoustic source is selectively taken into account by the signal processing section in an output sound of the hearing aid such that the local acoustic source is at least acoustically prominent and is therefore better perceived compared to another acoustic source for a hearing aid wearer.

Abstract: A method for designing a prosthetic device includes acquiring a three-dimensional image of an anatomical surface. A rules script for automatically performing a plurality of image processing rules using a script interpreter is executed. For each particular rule of the plurality of rules, one or more anatomical features that are relevant to the particular rule using a surface shaping engine are determined, the one or more determined anatomical features are automatically segmented from the acquired three-dimensional image using a feature detector, and the particular image processing rule is performed on the acquired three-dimensional image based on the automatically segmented anatomical features using a CAD tool. A prosthetic device design is produced based on the three-dimensional image upon which the rules of the plurality of image processing rules have been performed.

Abstract: Method for processing an input signal in a hearing aid, with the input signal being broken down into a discrete signal for each source relative to an acoustic signal, with the discrete signals being assigned to a spatial position of the source and with the discrete signals being output, or output attenuated, relative to the spatial position.

Abstract: The invention relates to a method for a hearing aid wearer to actively operate a hearing aid. A signal processing section of the hearing aid has a demixing module for separating audio signals and a postprocessor module which sets up a hold mode of operation for the hearing aid. An audio signal, which is preferred by the hearing aid wearer, from an ambient sound, is tracked and selected by virtue of the hearing aid wearer transmitting to the hearing aid a command which sets up the hold mode of operation in the signal processing section of the hearing aid for a certain period. The signal processing section tracks the preferred audio signal and selectively takes account of it in an output sound from the hearing aid such that it is audibly highlighted for the hearing aid wearer in comparison with another audio signal and is thereby perceived better.

Abstract: It should be possible to quickly and effectively adjust a hearing aid even in the high-frequency range above 8 kHz. For this purpose it is provided that an open-loop gain measurement is carried out in the upper frequency range and a maximum amplification or a frequency-dependent maximum amplification curve is fixed. This maximum amplification in the high-frequency range should not be exceeded. The hearing aid wearer can then optionally select one of a plurality of amplification curves located there below. In the low-frequency range a conventional amplification adjustment is carried out for example by a prescriptive audiogram-based formula. A hybrid adjustment procedure that is easy to carry out is thereby provided for the entire frequency range.

Abstract: To enable hearing apparatus feedback to be reliably detected, it is provided that the hearing apparatus has an analyzer for analyzing the resonant behavior of the overall system as a function of a modification of the signal processing device and for determining from the analysis result a feedback variable constituting a measure of the feedback. On the basis of the feedback variable, an adaptive compensation filter, for example, can then be step-size-controlled to compensate the feedback.

Abstract: An optically unnoticeable and acoustically improved behind-the-ear hearing device having a housing which can be worn behind the ear, a signal processing facility which is arranged in the housing, and which comprises an optoelectrical converter, and at least one optical microphone is provided. The optical microphone is arranged outside the housing and can be positioned in the concha or in the auditory canal. Furthermore, the optical microphone is connected to the signal processing facility by way of an optical wave guide for optical signal transmission purposes. An optical microphone of this type can be realized small and in an unnoticeable fashion on/in an otoplastic, such that during the acoustic recording, the typical frequency behavior through the concha can also be used.

Abstract: A method for detecting anatomical features in 3D ear impressions includes receiving a 3D digital image of a 3D ear impression, obtaining a surface of the ear impression from the 3D image, analyzing the surface with one or more feature detectors, the detectors adapted to detecting generic features, including peak features, concavity features, elbow features, ridge features, and bump features, and derived features that depend on generic features or other derived features, and forming a canonical ear signature from results of the detectors, where the canonical ear signature characterizes the 3D ear impression.

Abstract: The object is to take better account of subjective perceptions when setting a hearing device or a communication system, especially a hearing aid. Therefore, an automatic setting of the hearing device by automatically analyzing the hearing situation in which the hearing device is located, and automatic setting of a parameter of the signal processing device of the hearing device relative to the hearing situation in a first parameter range is provided. In addition, manual setting of the parameter of the signal processing device to a value in a second parameter range outside the first parameter range takes place, with the automatic setting in the first parameter range being ended by this. With this semi-automatic control, the user can find an individual compromise between effectiveness and artifacts of a signal processing.

Abstract: A method and system for side detection of an undetailed 3D ear impression is disclosed. In order to determine whether a received 3D undetailed ear impression is a left or right ear impression, a local coordinate system of the 3D undetailed ear is defined based on side independent features of the 3D undetailed ear impression. A skeleton (or center spline) of the 3D undetailed ear impression is detected, and it is determined whether the 3D undetailed ear impression is a left or right ear impression based on the skeleton and the local coordinate system.

Abstract: A method is described for reduction of occlusion effects in an acoustic appliance which closes an auditory channel, wherein an audio signal in the transmission path of the acoustic appliance is processed by a signal processing unit and is emitted via an output transducer, which is arranged in the auditory channel, as an acoustic signal. A resultant sound signal is then detected by an auditory channel microphone and is supplied to a variable loop filter which is arranged in a feedback loop of an occlusion reduction unit for the acoustic appliance. The output signal from the loop filter is injected into the transmission path of the audio signal. The occlusion reduction unit is in this case controlled adaptively, with at least one signal from the transmission path of the audio signal and/or from the feedback loop being used to control the loop filter for the occlusion reduction unit.

This music device can, for example, be a tuner with tone pitch analysis or sound playback, a metronome and/or a tone pitch processing unit. A remote control for receiving pieces of music and for playback via a hearing device may also be provided.

Abstract: The size of measuring boxes for hearing apparatuses and in particular for hearing devices is to be reduced, with the efficiency of the measuring box in respect of attenuating interference noises being maintained or improved. A measuring box is thus proposed, which comprises an interference signal recording facility for recording an interference signal. Furthermore, provision is made in the measuring box for a signal generating facility to generate a compensation signal which is phase-opposed to the recorded interference signal, so that the interference signal can be compensated for by the compensation signal. The interference noise attenuation is thus achieved here by an electronic active part, so that the quality demands on the measurement space can be reduced and its size thereby decreased as well.
