Abstract: 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.

Abstract: A transmission system for rearing devices is provided that, in spite of having less energy available, allows for a transmission relatively safe from interference. Such a gearing device has a self-exciting oscillation circuit as an antenna that enables an inductive coupling in the long-wave range. Additionally, or alternatively, a hearing device is provided with a receiving device that comprises a median filter device with which a median value can be determined from a plurality of values for noise signal prevention.

Abstract: The production of a hearing aid device suitable for wireless signal transmission is simplified by providing fastening elements connected as one piece with the housing shell. The fastening elements serve for placement and fastening of an antenna or coil in the housing shell of the appertaining hearing aid device. The production of a hearing aid device with a corresponding antenna or coil is thereby simplified. The alignment of the antenna or coil in the housing shell can also already be optimized using a computer model of the housing shell.

Abstract: In a digital hearing aid device with an output amplifier having a sigma-delta modulator, the output transducer has a high current consumption even when no output signal perceivable as an acoustic output signal is generated. A linear digital filtering in connection with the sigma-delta modulation reduces the number of the high-frequency edges in the (typically) pulse-density-modulated output signal.

Abstract: A hearing aid and a corresponding method are provided in which address data and/or channel data with respect to a plurality of signal sources are stored in a memory of the hearing aid. As a result of a priority-driven address management system, the hearing aid user can very conveniently automatically engage in communication with an interface having the highest priority.

Abstract: A remote control device is provided for a hearing device, and which comprises an input interface which receives input information. A conversion device converts the input information into hearing device control commands. A transmission device transmits the hearing device control commands to the hearing device.

Abstract: The invention is directed to a modular hearing aid device having a microphone module that comprises a microphone module housing and at least one microphone, and having a hearing aid device module that comprises a hearing aid device module housing, whereby the microphone module housing supplements the hearing aid device module housing to form a housing of the hearing aid device having a uniform effect, and whereby the microphone module and the hearing aid device module are detachably connected, and whereby the hearing aid device module comprises at least one microphone.

Abstract: A hearing device with a plastic mold arranged in the ear, in other words a hearing device shell or an otoplastic, features a loudspeaker in its interior. A cerumen protection system extends from the loudspeaker to the surface of the plastic mold. In accordance with the invention, a microphone is arranged in the cerumen protection system.

Abstract: Hearing aids are to be further miniaturized and simplified in terms of their manufacture. Provision is made for this purpose for the microphone facility for a hearing aid to be manufactured from at least one silicon microphone, said silicon microphone being attached to a MID plastic carrier (Molded Interconnected Device). This plastic carrier then features the double functionality of a microphone housing segment and a printed circuit board.

Abstract: In a digital hearing aid device with an output amplifier having a sigma-delta modulator, the output transducer has a high current consumption even when no output signal perceivable as an acoustic output signal is generated. A linear digital filtering in connection with the sigma-delta modulation reduces the number of the high-frequency edges in the (typically) pulse-density-modulated output signal.

Abstract: It is intended with a hearing aid that an electromagnetic interference field generated in the hearing aid device itself and acting on a transmit and/or receive antenna (7) should be attenuated or compensated for in a simple fashion. It is proposed to this end that the supply lines (6C, 6D) of the hearing aid device (1) should be used to position loops (8, 9) specifically, so that an opposing field is generated to attenuate or compensate for the interference fields present at the site of the transmit and/or receive antenna (7).

Abstract: Cerumen are effectively kept away from the earphone of a hearing aid by the earphone having a lager lateral sound exit opening partly covered by a band. Polytetrafluoroethylene film is suited as material for the band. For protection against larger cerumen constituents, the earphone can be additionally encapsulated by a capsule having a cover. To this end, the earphone is seated in the capsule vibration-damped by means of damping elements.

Abstract: In a hearing aid system having at least two hearing aid devices acoustic field characteristics are generated in the hearing aid devices and are transmitted between the hearing aid devices for adapting the signal processing units to different hearing situations. Both hearing aid devices are thus always operated in the same hearing program.

Abstract: The manner of informing a user about the current setting of manually adjustable parameters in a hearing aid is to be improved. In addition it is proposed that an information signal be transmitted to the user, on the basis of which said user is informed that an upper or lower end of the value range for a parameter to be set has been reached, so that further activation of the relevant actuator remains ineffective in respect of parameter setting. The invention is used in particular in conjunction with actuators which do not have a mechanical end stop, whereby the user could identify that the upper or lower end of the value range of the parameter to be set has been reached.

Abstract: 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 “audio reception” mode than on the hearing aid device that is in a passive “audio reception” mode.

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: 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: 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.
