Abstract: It is intended to improve and automate the calculation of calibration filters connected downstream from the microphones of an RGSC beamformer. To this end it is proposed that an adaptive calibration filter calculation unit be used, by means of which calibration filters are calculated from the output signals of adaptive blocking filters such that the power of an output signal of a blocking filter subtracted from a reference signal and filtered by means of a calibration filter respectively is minimized. The calibration filters connected downstream from the microphones are then replaced by the calibration filters thus determined.

Abstract: Structurally simple transmit/receive circuits for hearing devices are to be able to be deployed for higher frequencies as well. It is therefore proposed according to the invention that at least two PIN diodes should be connected in an anti-parallel manner between the receive oscillating circuit and the amplifier connected thereto to protect the amplifier. A capacitance diode can optionally be expanded so that larger component tolerances can be permitted for the circuit.

Abstract: With a hearing aid device barometric pressure equalization is intended to be achieved in a simple and economical manner in a sound canal between an earpiece and a cerumen protection system with a gas-tight membrane. To this end a pressure equalization canal is proposed, which opens into the sound canal. The pressure equalization canal preferably connects the sound canal to a vent. It can be produced in a simple manner when manufacturing the housing of the hearing aid device using a computer-aided manufacturing method.

Abstract: The production of a hearing aid device can be simplified by the use of a microphone module with a plurality of microphones. To attach and electrically contact the microphones, the invention provides a microphone carrier with three-dimensionally directed conductor traces in MID technology. In a complicated microphone arrangement with a plurality of microphones, a single microphone module can thereby be used on which all microphones of the hearing aid device are attached and electrically connected.

Abstract: The protection of the ports of a hearing device, in particular microphone ports, is to be more easily operable in terms of installation and replacement. Provision is made for this purpose for protection to be provided by an adhesive film with a plastic membrane, which is essentially acoustically permeable, and an adhesive layer, which is attached to the plastic membrane. The adhesive is cut out in a predetermined shape at least one specified location on the plastic membrane. It is thus possible to affix an easily operable common microphone protection system to the hearing device shell, for example for a directional microphone with several microphone ports.

Abstract: The phase differences of microphones of a hearing aid microphone are to be reduced. To do this, the level of an output signal of a directional microphone is compared with an omnidirectional signal. If the level of the output signal of the differential directional microphone is above the level of the omnidirectional signal, this level difference is minimized by an adaptive, frequency-selective transit time compensation in individual frequency bands and phase matching of the microphones is thus achieved. By means of an alternative method, microphone matching is achieved in that the measurable delay of the two microphone signals is adaptively limited in individual frequency bands to a maximum value corresponding to the sound transit time between the microphones. Phase matching without knowing the position of a sound source can thus be achieved.

Abstract: A method for modeling a 2-dimensional tubular structure in a digitized image includes providing a digitized image of a tubular structure containing a plurality of 2D balls of differing radii, initializing a plurality of connected spline segments that form an envelope surrounding the plurality of 2D balls, each the spline segment Si being parameterized by positions of the ith and i+1th balls and contact angles ?i, ?i+1 from the center of each respective ball to a point on the perimeter of each the ball contacting the spline segment Si, each the ?i affecting spline segment Si and Si?1, and updating the angles by minimizing an energy that is a functional of the angles, where the updating is repeated until the energy is minimized subject to a constraint that the envelope is tangent to each ball at each point of contact, where the envelope is represented by the contact angles.

Abstract: In a hearing aid device system with a hearing aid device which can be worn on or in the left ear of a user and a hearing aid device which can be worn on or in the right ear of the user for the binaural supply of the user, the aim is to reduce feedback tendency. To this end, it is proposed to transmit audio signals resulting from the microphone signals of the hearing aid devices in a crosswise fashion between the hearing aid devices and thus to emit an acoustic signal recorded by the microphone of a hearing aid device, after the signal processing and amplification, by means of the receiver of the respective other hearing aid device. In this way, the distance between each receiver and microphone, between which a feedback path exists, is essentially increased for the relevant audio signals.

Abstract: An acoustic actuator comprises a support layer (3), in which a self-supporting structure (1) is defined which is connected to the support layer (3) by means of at least two suspensions (7), at least one magnetostrictive layer (4) which has been put on the support layer (3) and is provided at least in part on the self-supporting structure (1), and means (2; 5) for generating a magnetic field in the magnetostrictive layer (4). The way in which the loudspeaker works is based on the magnetostrictive effect, which results in a change in the dimensions of the self-supporting structure in an alternating magnetic field. This causes the self-supporting structure to oscillate.

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: A wideband audio coding concept is presented that provides good audio quality at bit rates below 3 bits per sample with an algorithmic delay of less than 10 ms. The concept is based on the principle of Linear Predictive Coding (LPC) in an analysis-by-synthesis framework. A spherical codebook is used for quantisation at bit rates which are higher in comparison to low bit rate speech coding for improved performance for audio signals. For superior audio quality, noise shaping is employed to mask the coding noise. In order to reduce the computational complexity of the encoder, the analysis-by synthesis framework has been adapted for the spherical codebook to enable a very efficient excitation vector search procedure. Furthermore, auxiliary information gathered in advance is employed to reduce a computational encoding and decoding complexity at run time significantly. This auxiliary information can be considered as the SCELP codebook.

Abstract: The invention relates to a hearing aid with a signal processing unit and at least two microphones which can be coupled together to form directional microphone systems of a different order, where microphone signals emitted by directional microphone systems of a different order can be coupled together in a weighting dependent on the frequency of the microphone signals. The invention further relates to a method for operating a hearing aid of this type.

Abstract: A hearing device, in particular of a hearing aid, in addition to a first sound output device for acoustic supply to the ear of the user, has a second sound output device for output of a test sound in a room in which the hearing device is located. The hearing device has an acquisition device for acquisition of a response to the test sound from the room. Room acoustic information that can be used to control the signal processing of the hearing device is acquired from the response. The signal processing in the hearing device can be automatically adapted to the current room acoustic.

Abstract: A directional microphone for a hearing device should be easy for the user to operate. To this end it is equipped with an orientation sensor, such that it can be controlled as a function of orientation. It is for example possible in this manner to switch it to directional operation, when it is aligned horizontally. When it is aligned vertically, the directional microphone is for example switched automatically to omni-directional operation.

Abstract: If a hearing device user has become accustomed to the tone of a hearing device, it is difficult for him to change over to a new hearing device, since this normally possesses a different tone. Therefore, given a treatment with a second or subsequent device, the settings of the old hearing device can be acquired with a computer-controlled event and be considered in a first adjustment given the adaptation of the new hearing device. The new setting then results from the audiometric measurements, the data of the previous device, and if necessary further data. The tone of the new device is thus approximated to the old device.

Abstract: The present invention provides the ability to efficiently detect a defect of an earwax protection device membrane. To achieve this, a high contrast is set between the membrane and the associated carrier. If the membrane is torn, the carrier in the background can then easily be detected. A particularly suited brightness contrast between the membrane and the carrier is >0.1. In the case of a desired high color contrast, the color of the membrane should be spaced apart from the color of the carrier by at least 60° on a blue-yellow-red color circle.
