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 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: An antenna coil is present in a hearing aid device to wirelessly transmit signals between a hearing aid device and a further device. Due to the required miniaturization of hearing aid devices, only minimal space is available for the arrangement of the antenna coil in the hearing aid device. The invention therefore provides for winding the antenna coil around an existing electro-acoustic transducer in the hearing aid device or around a capsule surrounding the transducer. A comparatively large antenna coil, for which little additional space is required, can thereby be provided in the hearing aid device.

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: 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: Acoustic feedbacks can be caused by the aeration channel (5) that is present in hearing aid devices (2) wearable in the ear or hearing aid devices having an otoplastic wearable in the ear. In order to avoid this, it is provided that the aeration channel be subdivided into at least a first and a second sub-region, whereby the sub-region (5A) that is proximal when the hearing aid device (2) is worn or when the otoplastic is worn comprises a small cross-sectional area and a great length compared to the distal, second sub-region (5B).

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: For improving the automatic switching and control of hearing aid devices in view of respective auditory situation, the acoustic signal picked up by the hearing aid device is analyzed for noise signals. The control of the hearing aid device then ensues on the basis of the analyzed noise signals. Individual transmission parameters or entire hearing programs of the hearing aid device can be controlled or switched.

Abstract: A hearing aid device to be worn in the ear or a hearing aid device with otoplastic to be worn in the ear, has at least two aeration channels in combination with flow resistances arranged in the aeration channels that promote a flow from the enclosed auditory canal volume toward the outside in at least one aeration channel and a flow into the enclosed auditory canal volume in at least one other aeration channel. A flow through the enclosed auditory canal volume results therefrom, so that an air exchange ensues. This improves the wearing comfort of the hearing aid device and contributes to the prevention of diseases caused by a poor ventilation of the auditory canal.

Abstract: In a microphone with a microphone housing for arrangement in a hearing aid to be worn behind the ear having a hearing aid housing, respective sound entry nozzles with respective sound entry apertures are arranged at two opposite sides of the microphone housing. The sound entry nozzles discharge into a chamber at a side of the microphone membrane. The sound entry nozzles are introduced into the respective sound entry apertures in opposite sides of the hearing aid housing, and when the hearing aid is worn, the sound entry aperture of one sound entry nozzle is disposed approximately distally from the head and the sound entry aperture of the other sound entry nozzle is disposed approximately proximally relative to the head. The microphone is space-saving and is simple to arrange in the hearing aid.

Abstract: For the automatic choice of a hearing program, a hearing aid (1) detects whether it is located in the immediate vicinity of an external transmitter (10, 10′). The transmitter (10, 10′) generates a transmitter-specific signal so that an assignment of different transmitters can be made. In addition, in the case of the hearing aid (1), the current time of day and the day of the week can also influence the choice of the active hearing program.

Abstract: The invention concerns a monitor head for ultrasound control by pulse echo process, in particular for producing a brief ultrasound pulse, unipolar as far as possible, comprising an oscillator/transmitter (26) and an oscillator/receiver (32), each provided with electrodes (28, 30, 34, 36). The oscillator/transmitter (26) and the oscillator/receiver (32) are made of the same material. The oscillator/transmitter (26) and the oscillator/receiver (32) are arranged directly one behind the other, in the sound propagation direction, in particular flat-bonded one on the other.

Abstract: An electroacoustic miniature transducer has at least one drive and one membrane. The membrane is divided into a number of membrane regions. For the connection of two adjacent membrane regions, an elastic element is arranged between these regions. This transducer design achieves an expansion of the transmission characteristic of the miniature transducer as high frequencies are approached.
