Abstract: A method for setting a device for presenting sound specimens for the individual tuning of a hearing device to be worn on the body of a hearing device wearer. The method includes providing and presenting a noise signal by the device, receiving the presented noise signal by at least one microphone of the hearing device, comparing the received noise signal or a signal derived therefrom with a reference signal stored in the hearing device, and emitting a status signal by the hearing device in dependence on the comparison. In this manner, simple and precise setting of the device for emitting sound specimens for calibration purposes occurs.

Abstract: A hearing device and an associated method use an adaptive directional microphone for suppressing feedback. The hearing device includes an adaptation unit which sets the directional microphone so that a sound signal fed back from an earpiece of the hearing device to the directional microphone is attenuated. Acoustic feedback is advantageously attenuated or suppressed simply in an artifact-free manner.

Abstract: The production of a hearing aid housing shell or ear mold that can be worn in the ear should be simplified and improved. For this, a prefabricated component, such as a frame for holding an electronics module or a receiver adapter, is positioned in a rapid prototyping instrument. There, the component is integrated into the housing shell or ear mold by the subsequent production of the housing shell or ear mold. This avoids connecting the component to the housing shell or ear mold in a further method step after producing the housing shell or ear mold.

Abstract: Optimized hearing aid parameter settings are automatically determined from a multiplicity of data obtained by applying different test methods for testing the auditory perception of a person. Data pertaining to the auditory perception (audiological data) of the user are first obtained by different test methods. The data from the individual tests can be incomplete, inconsistent or untypical, or even erroneous. However, the subsequent combination of where possible all available data in a computational unit affords the possibility of automatically obtaining hearing aid parameter settings by way of which a hearing aid operated thereby compensates the present loss of hearing of the relevant user in an optimized fashion.

Abstract: The adjustment of the signal processing carried out by a hearing aid to the individual hearing loss of a user is intended to be simplified. For this purpose, a number of predefined adjustment programs, from which the user selects a suitable program by operating an operating element, are provided in the hearing aid. Neither a visit to a hearing aid acoustician nor special adjustment devices is/are required for adjustment.

Abstract: The fine-tuning of the signal processing in a hearing aid or hearing aid system to the individual user should be simplified and improved. For this, the current hearing situation is recognized automatically and the user is automatically presented with a selection of questions from a comprehensive list of questions as a function of the hearing situation. A user input as a reaction of the user to the selected questions leads to the tuning of at least one parameter relating to the signal processing in the hearing aid.

Abstract: A hearing aid has protection against unintentional operation. The protection against unintentional operation is provided for the purpose of suppressing erroneous, mistaken or unintentional user inputs for changing settings of a hearing aid. The hearing aid contains signal-processing electronics arranged in a housing and an operating element actuated manually, arranged externally on the housing. A locking arrangement is configured to lock the operating element in respect of manual actuation, and an unlocking arrangement is configured to deactivate the locking arrangement. The unlocking arrangement contains at least two sensors actuated manually, which are arranged spatially separate from one another on the housing. The unlocking arrangement deactivates the locking arrangement only during and/or in a limited time period following simultaneous manual actuation of the sensors. The spatially separate arrangement of the sensors can suppress an accidental undesired actuation.

Abstract: A cavity examination device has an optical receiving element, such as a lens or a camera, and enables insertion into the cavity, in which the reception element does not touch the cavity wall. The cavity examination device has an optical receiving element which receives light emitted or reflected by a wall of a cavity and a screen made of a flexible material. The screen has a first opening and a second opening. The cross section of the second opening is larger here than the cross section of the first opening, and the second opening is selected with regard to the shape and dimension such that, predominantly, it resiliently rests against the wall of the cavity. The screen is attached by the first opening to a body of the cavity examination device on a side of the cavity examination device, which is inserted first into the cavity.

Abstract: A hearing aid has a housing, a signal-processing arrangement housed in the housing, an LED, an actuatable switching element arranged on the housing, and a battery. The LED is connected to a positive pole of the battery with its anode connector and to a first connector of the signal-processing arrangement with its cathode connector. The signal-processing arrangement is formed with a monitoring unit, which switches the first connector if there is a drop below a first threshold voltage such that the cathode connector can be connected to a negative pole of the battery.

Abstract: For particularly good adaptation to a given hearing situation, an in-the-ear hearing device which has a housing with a channel in the housing that is designed as a through-opening for sound and air between the interior of the ear and the environment outside the ear, the channel is provided with a structural element for changing the size of the through-opening at at least one position. The structural element is a valve formed with electroactive material and the size of the through-opening is adjusted by application of a voltage to the valve.

Abstract: In an embodiment, a hearing aid is provided. The hearing aid may include a behind-the-ear component, a sound tube coupled with the behind-the-ear component at its one end, and a loudspeaker coupled with the sound tube at the other end of the sound tube opposite to the behind-the-ear component. The hearing aid may further include a joint connected between the loud-speaker and the sound tube, wherein the joint is moveable or flexible such that a degree of freedom in movement is provided in a direction substantially perpendicular to an insertion direction of the loudspeaker into an ear canal.

Abstract: A hearing aid device includes a processing unit and a receiving unit adapted to be coupled to transmit an electrical signal from the processing unit to the receiving unit. The processing unit has a wireless transmitter and a transmitter seal for covering the wireless transmitter and the receiving unit has a wireless receiver and a receiver seal for covering the wireless receiver. The electrical signal is transmitted from the wireless transmitter to the wireless receiver wirelessly. The electrical signal may be transmitted by induction. The transmitter seal and the receiver seal prevent any environmental influences from acting on the hearing aid device and thus protect the hearing aid device from malfunctioning or becoming short circuited. Magnetic connectors and/or mechanical connectors are provided for a stable contact between the processing unit and the receiving unit.

Abstract: A manually-actuatable volume adjuster for a hearing aid and a hearing aid with the volume adjuster are user friendly, durable, hardly prone to errors, miniaturizable and energy-saving. The adjuster includes a manually-actuatable pushbutton switch and an infrared sensor for acquiring orientation and/or position of a manual movement carried out for the actuation. The infrared sensor is only activated while the pushbutton switch is actuated and/or during a restricted time period following that actuation. The hearing aid with the adjuster includes standard sensors as an infrared sensor and as a pushbutton switch. The infrared sensor permits construction of the adjuster without moveable mechanical actuating elements and avoids touch surfaces or contact surfaces susceptible to wear-and-tear. The increased energy consumption of an infrared sensor is counteracted by the functional combination with the pushbutton switch.

Abstract: A receiver tube for connecting a receiver to a hearing aid instrument and a hearing aid instrument with a receiver tube, include a connection which ensures good acoustic stability and low feedback tendencies, can be produced in an uncomplicated manner and has high impact and shock strength. The receiver tube includes a receiver connector constructed as a cup at least partly holding a receiver when connected together. The receiver connector includes a form-locking mechanism for a receiver and a flexible element for locking the receiver. The form-locking connection simplifies installation of the receiver during production or replacement by requiring neither application of a force, as when pretensioning or expanding force-locking connections, nor establishment of an adhesive connection. The locking mechanism can be opened/closed by the flexible element. The cup-shape of the receiver connector contributes to increased rigidity and reliability of the form-locking connection to the receiver and an acoustic shield.

Abstract: A hearing aid has an interchangeable earpiece, which, on its own and separately from further components, can be replaced in a simple fashion and without great complexity, and without specialist tools. The hearing aid has a housing of a multi-part design and a receiver and a signal processing device within the housing. The receiver is arranged detachably in a first housing part and the signal processing device is disposed in a further housing part and the two housing parts are detachably interconnected. A detachable locking mechanism connects the housing parts. The receiver is connected to the signal processing device by way of a detachable electrical connector with a receiver-side and a signal-processing-device-side electrical contact. At least one of the electrical contacts is elastic.

Abstract: A filter bank configuration for a hearing device has filters in an analysis filter bank and corresponding filters in a synthesis filter bank that are coupled pair-wise to form a channel in each case. In order to compensate for a hearing loss, sub-band signals are amplified in the individual channels with the aid of multipliers. In the process, an audible distortion of an output signal Y of the filter bank configuration as a result of differences between amplification factors of the multipliers of neighboring channels should be prevented. Here, at least one channel changes a phase of a sub-band signal transmitted by the channel such that a difference between a group delay of the filter bank configuration and a prescribable reference value is reduced for at least one predetermined frequency. The filter bank configuration is particularly suited to hearing aids.

Abstract: A housing for a hearing aid appliance includes a housing shell which is made, at least in a partial region, from a material which forms a smooth exterior surface in the partial region. Recesses are formed in the material beneath the smooth exterior surface. A material layer located between the recesses and the exterior surface has such a layer thickness that the material layer is at least semitransparent for light, as a result of which the recesses are visible through the material layer when the housing shell is illuminated. A hearing aid appliance having such a housing shell is also provided as well as a method for producing such a housing shell for which a rapid-prototyping process is employed and by which the recesses are produced by not solidifying the starting material there.

Abstract: A system and method reconstruct an anatomical impression. The system contains a light signal generating device for generating a light signal directed toward a synthetic test body having the anatomical impression. The light signal is directed toward the synthetic test body such that the light signal is attenuated upon passing through the synthetic test body. A sensor captures the attenuated light signal through the synthetic test body and converts the captured attenuated light signal into digitized image information. The system further includes a digital reconstruction device for reconstructing the digitized image information based on measurement of light attenuation to generate a three-dimensional volume of the anatomical impression.

Abstract: A hearing apparatus and an associated method for suppressing feedback include a microphone emitting a microphone signal and a receiver picking up a receiver signal by subtracting a compensation signal from the microphone signal. The hearing apparatus includes a number of preset static first compensation filters for forming first compensation signals from the receiver signal and a first selection unit, which selects a first compensation signal in such a way that a feedback signal caused by the feedback is minimal in the receiver signal. An advantage thereof is that adaptation artifacts cannot occur.
