Abstract: To assist in the standardization of communication protocols and individual register models of various hearing devices, the register in the DSP/ASIC of a hearing device has a standardized interface in the DSP/ASIC. An application-specific, universal, generic command set that is transferred via the communication interface can be used therewith. Thus command set can be standardized over hearing device families, IC generations and across manufacturers, such that a universal software for adaptation of hearing devices can be achieved.

Abstract: The cleaning and exchange of components of the hearing aid which is necessary at regular intervals due to the conventional contamination is uncomfortable and expensive. The housing (G) and any protective devices (K) which are to protect from contamination, are provided with a dirt-resistant layer. In this way, the dirt adheres less strongly to the hearing aid, so that if necessary it can be removed by means of tapping.

Abstract: In a hearing aid with a magnetic field-controlled switch and a method for operating such a hearing aid, the magnetic field sensor for automatically switching the hearing aid is miniaturized and made more cost-effective by the use of a ferrite component as the magnetic field sensor. This component can be evaluated by a Wheatstone bridge circuit which is fed by an oscillator. In this context, a measuring amplifier with a threshold value detector supplies a corresponding switching signal for the hearing aid.

Abstract: Microphone equalization is implemented in a directional microphone system of the second or a higher order with at least three omnidirectional microphones. Initially, the signal levels of the microphone signals generated by the three omnidirectional microphones are compensated. The phase is subsequently varied in one of the three microphone signals until the signal levels of the directional microphones of the first order that are formed from the three omnidirectional microphones, are also compensated.

Abstract: Directional hearing is improved given the binaural coverage for a hearing aid user with two hearing aid devices wearable at the ears. The respective signal transit times and/or signal amplitudes and/or amplifications of an electrical signal are respectively measured in a signal path between an input transducer and an output transducer and that data with respect to the measured signal transit times and/or signal amplitudes and/or gains is transmitted onto the respectively other hearing aid device. As a result, the signal transit times and the signal amplitudes of the electrical signals through the two hearing aid devices can be matched to one another. The hearing aid devices thus cause no phase or amplitude distortion, and the natural phase shift as well as the natural amplitude difference of a sound signal incident from a specific direction are thus preserved. The directional information is thus also preserved for the hearing aid user.

Abstract: A comfortable device that combines the functionality of a hearing aid with that of a headset is to be provided. A hearing aid device (H) is thus provided which comprises a rotary switch, on which is arranged a directional microphone. In a first rotary position corresponding to the hearing aid mode, the directional microphone points horizontally forwards, whilst in the second rotary position corresponding to a telephone mode, the directional microphone points towards the mouth of the wearer. The hearing aid device is switched into the corresponding mode by rotating the directional microphone.

Abstract: A system and appertaining method are provided for electronically detailing an impression of an ear canal of a patient. A digitized geometric model of the impression is created, and a software tool is utilized to determine a bony part or canal direction, as well as first and second bends of the impression. An aperture of the impression is determined, and a cutting plane through the aperture is calculated such that the normal vector through the aperture plane aligns with a normal vector of the second bend plane. On establishing this congruence, modeling parameters optimized for modeling wireless based hearing instruments are evoked to optimized and automate design. This calculation can then be utilized for either manual or automated shaping and cutting operations.

Abstract: Between ITE hearing aids for binaural hearing assistance, energy-saving communication is made possible by disposing an antenna device with a preferred direction of transmission in the hearing aid housing such that, in a state in which the hearing aid is attached to or inserted one ear of the patient, the preferred direction of transmission is substantially toward the other ear of the patient. In this way it is ensured that the directions of transmission of the two hearing aids in the fitted state lie substantially on a straight line, so that optimum transmission can be achieved.

Abstract: To allow bidirectional data communication to be realized in hearing aids which have only a restricted installation space, the earphone, i.e. the electroacoustic transducer unit, is used as the transmitter and the telephone coil as the receiver for high-frequency signal components. This makes it possible to dispense with the installation of an additional antenna, generally of a large volume, that is optimized for transmitting and receiving operations. If appropriate, a small additional antenna may also be used purely as a receiving antenna for high-frequency signals.

Abstract: Due to the clocked mode of operation, electromagnetic interference signals originate from digital hearing aid device or hearing device systems with the clock frequency and its harmonics. These can disrupt the wireless signal transmission between the hearing aid device or hearing device system and a further device. To prevent these disruptions, the invention provides a jitter unit that is connected with the clock generator and causes frequency oscillations in the clock signal. The interference signals caused by the clock signal are thereby lowered with respect to their amplitudes, whereby an interference-free signal transmission is enabled between a transmitting and/or receiving unit connected with a hearing aid device and an external device.

Abstract: An acoustic module for a hearing aid device has at least one microphone and at least one earphone (acoustic output transducer) combined together as a unit, the unit including a signal-processing unit for feedback suppression that is connected with the microphone and the earphone. Feedback signal portions are removed from the microphone signal by the signal-processing unit. The acoustic module places acousto-mechanical components within a unitary component, with acousto-mechanical characteristics that can be measured and included in the signal processing for feedback suppression.

Abstract: The interference noise suppression in hearing devices is to be optimized. A hearing device, in particular a hearing aid (HG) is thus proposed, comprising a directional detection device (RM) for detecting a direction from which an audio signal comes in from the sound source (Q), and a signal processing device (VE) for processing the incoming audio signal as a function of the detected direction. An interference classification device (GK) for classifying the audio signal arriving from the sound source (Q) is also processed as a function of the signal class. With the aid of a signal generator (SG) and a receiver (H), a hearing aid wearer can, for example, be informed about the type and direction of the noise, said type and direction of the noise otherwise being so heavily attenuated by the interference noise suppression that the noise is no longer perceivable to said hearing aid wearer.

Abstract: Pocket hearing aids are to be designed to be more comfortable. To this end there is provision on one hand for a wireless communication connection to be established between the microphone part and the earpiece part. To this end the microphone device of the pocket hearing aid has an appropriate electronics section (1) and an antenna (4), which can simultaneously be used as a clip. In order on the other hand to be able to dispense with feeding in external signals over a cable connection, the microphone device further features an adapter connector (5) with which for example it can be plugged in directly to a training device, a stereo device or a mobile telephone.

Abstract: Active otoplastics (3) with integrated earpieces (4) are to be acoustically optimized. There is provision here for forming a sound outlet (8) into the otoplastic in accordance with acoustic conditions. If the sound outlet (8) has the form of an exponential horn, this results in advantages for supply of high tones. The earpiece (4) can be secured with the aid of an adapter (5) into the otoplastic (3) so that it can be exchanged.

Abstract: A device to transmit and receive data for remote control of hearing devices has a reduced size achieved by the transmitter coils of the transmitter and the receiver coil of the receiver being wound around a common, shared core. Moreover, a protective capacitor that is used to protect the receiver is at the same time used as a correction capacitor to correct the resonant frequency of a reception oscillator circuit.

Abstract: The individual adaptation of a hearing device to a hearing device user is simplified by providing that the hearing device user manually selects the amplification in a specific auditory situation and initiates an adjustment event, such that this auditory situation is physically measured. From this, a new characteristic line field is determined, such that a corresponding amplification can be adjusted in a new auditory situation. Via this possibility of the self-adjustment, it is no longer necessary that the hearing device user seeks out an acoustician for adjustment.

Abstract: In a hearing aid having a microphone system composed of multiple microphone units, in order to avoid artefacts from being created when switching between different directional characteristics, the signal levels of microphone signals that respectively originate from different microphone units with different-order directional characteristics are matched with regard to a reference signal. The switching or superimposition is then always carried out between microphone signals with the same signal level, so that the switching or superimposition does not result in any sudden level changes.

Abstract: In a hearing aid device and operating method with automatic switching of the hearing aid voltage supply for an external component connected to an audio input of he hearing aid via a single audio voltage supply contact. A load detection device measures the electrical load at the audio input and switches either the unregulated voltage of the hearing aid battery or the regulated voltage of a voltage regulator in a preamplifier of the hearing aid to the audio input dependent on the measured load.

Abstract: A remote control for a hearing aid device prevents incorrect operation by having operating elements that effect a signal transmission from the remote control to a hearing aid device disposed on a first side of the remote control housing, and operating elements that additionally effect a signal transmission from the hearing aid device back to the remote control disposed on a second housing side of the remote control. The first and second housing sides are disposed in an easily tactilely distinguishable relation to each other, such as by being substantially orthogonal. The different functions of the operating elements and therefore can be differentiated purely by contact with the remote control.

Abstract: For improving the directionality of a hearing aid having a microphone system formed by two or more microphones without in the process creating an increase in the microphone noise that the hearing aid wearer finds to be disturbing, the microphone system is adjusted statically or adaptively taking into account the individual rest hearing threshold and/or taking into account the individual masking threshold for the microphone noise that is produced by the microphone system. The greatest possible extent of directionality thus can be allowed, without the hearing aid wearer in the process finding the microphone noise that is produced by the microphone system to be disturbing.
