Abstract: A hearing device has a signal-processing apparatus for processing an input signal into an output signal, and a feedback-canceller apparatus for reducing feedback artifacts on the basis of the input signal and the output signal. The feedback-canceller apparatus has an adaptive, first filter, for establishing a set of filter coefficients for a predefined feedback situation. The feedback-canceller apparatus is configured to store the set of filter coefficients. It has at least one second filter, which can be operated directly parallel to the first filter on the basis of the stored set of filter coefficients. The adaptive, first filter can be continuously adapted to a current feedback situation, and the feedback-canceller apparatus is configured such that in the current feedback situation it automatically selects either the first or the second filter. As a result, it generally only requires a simple switchover, but not a complete adaptation.

Abstract: In a hearing aid provision can be made for a housing that is worn outside of an auditory canal of a user. Then, sound or electrical signals are conducted into the auditory canal from the housing. To this end, provision can be made for a conducting element such as a sound tube or a cable. The conducting element is then connected to the housing via a coupling element. This connection must be embodied such that the coupling element does not detach from the housing on its own accord. The user must be able to remove the coupling element and the conducting element from the housing in a simple fashion in order e.g. to be able to clean the former two parts. Accordingly, a coupling element and a housing can be interconnected in a detachable fashion, with this connection containing a dovetail joint for the hearing aid.

Abstract: A device for inserting a pin into a hearing aid has a gripper embodied in the shape of a cylinder. In an end face the gripper has an aperture by way of which a pin that is to be placed in the hearing aid is picked up. For this purpose the gripper is pressed onto the pin. After the pin has been successfully placed in the hearing aid, pressure is then applied, by squeezing with the hand for example, to the lateral surface of the gripper. This causes a size of the aperture to be changed in the radial direction, as a result of which the pin clasped by the gripper is released. By this means it is advantageously possible to pick up a pin that is to be placed in the hearing aid and install it while making use of only one hand and without recourse to a tool such as a pair of tweezers, for example.

Abstract: The speech perception of hearing-aid wearers and wearers of other hearing devices is intended to be improved. To this end, a method for training the speech perception of a person, who is wearing a hearing device, is provided, in which a first speech component is presented acoustically and the latter is identified by the person wearing the hearing device. Subsequently, there is automated modification of the acoustic presentation of the presented speech component and the aforementioned steps are repeated with the modified presentation until, if the identification is incorrect, a prescribed maximum number of repetitions has been reached. Otherwise, if the first speech component is identified correctly or if the number of incorrect identifications of the first speech component is one more than the maximum repetition number, a second speech component is presented acoustically. This allows a plurality of speech components to be trained in respectively a number of steps.

Abstract: A hearing device has a feedback suppression unit. The hearing device further has a low-pass filter characterized by a first cut-off frequency, which couples out a low-frequency signal component from an output signal of the hearing device, and a high-pass filter characterized by a second cut-off frequency, which couples out a high-frequency signal component from the output signal of the hearing device. A frequency shift unit shifts the frequency of the high-frequency signal component to higher frequencies. A gap exists between the first and the second cut-off frequency. As a result of the different limit frequencies, signal distortions caused by frequency shifts are effectively suppressed. Feedback is suppressed continuously and rapidly at higher frequencies.

Abstract: In a hearing device or hearing aid, provision can be made for a sound tube or an in-the-ear loudspeaker to be held in an auditory canal of a user by an earpiece. To couple a sound tube to an earpiece, a connection element can be provided on the sound tube, which connection element can be connected to a connection element for the earpiece. This connection must be detachable so that a user can remove the earpiece from the sound tube. Nevertheless, it must be possible to transmit such a large force over the connection that the earpiece can once again be pulled out of the auditory canal. The object is to simplify a detachable connection for coupling an earpiece to a sound tube or an in-the-ear loudspeaker. Accordingly, the connection element for the earpiece is provided as an independent component, which is attached in or on the earpiece.

Abstract: Feedback in a hearing device and, more particularly, in a hearing aid should be compensated for before it becomes audible. To this end, a method is proposed for compensating for a feedback signal in a hearing device with an input-transducer apparatus, a signal-processing apparatus and an output-transducer apparatus, in which method a feedback signal is compensated for, which feedback signal is fed back to the input-transducer apparatus from the output-transducer apparatus or the signal-processing apparatus. More particularly, a probability of having a plurality of notches, equally spaced apart from one another, in the spectrum of an input signal is established, which input signal originates directly from the input-transducer apparatus or which is a difference signal between the signal directly from the input-transducer apparatus and a compensation signal serving for compensation. The compensation is modified or the signal-processing apparatus is amplified as a function of this established probability.

Abstract: A receiver tube for a hearing aid has an integrated strain relief. A receiver mounted at the end of the receiver tube is normally worn in the auditory canal of a hearing aid wearer. It is pulled out of the auditory canal by pulling at the receiver tube or also separated from the receiver tube for the purpose of cleaning or exchange. Due to the tensile forces, the flexible receiver tube is stretched and elongated. This longitudinal extension may under certain circumstances amount to up to several millimeters and load or even damage the connection of the less extensible conductor to the receiver or to the hearing aid extending through the receiver tube due to tension. The novel receiver tube has a strain relief with a strain aid that is inexpensive to produce and benefitting a small diameter, has a high visual transparency and a high flexibility of the receiver tube.

Abstract: An apparatus for recording a shape of a section of the human ear is provided. The apparatus has a recording device for recording a spatial shape of a first and a second subsection of the section and for recording a position or a variable representing the position of the first and the second subsection relative to a predetermined optical feature of the section. The apparatus has an evaluation device for obtaining shape information about the section by combination of the shapes of the subsections based on the recorded positions or the variables representing the respective position. This enables a number of individual images to be joined together into a three-dimensional map based on natural features in the auditory canal, such as skin flecks or veins for example.

Abstract: A hearing aid can be inserted deep inside an auditory canal without the risk of injury. The hearing system has a hearing device that can be completely inserted into a human auditory canal, and a positioning device, which is attached to the hearing device in a self-retaining manner. The positioning device can be detached from the hearing device, when the latter is in the state where it is inserted into the auditory canal, and cannot or can only partly be inserted into the auditory canal because it serves as a stop on a section of the concha when the hearing device is being positioned. The positioning device is decoupled from the hearing device after placement and removed from the auditory canal.

Abstract: A hearing apparatus, more particularly a hearing aid, generally requires sound or electrical signals to be conducted from a housing, worn outside of an auditory canal of a user, to an earpiece which has been inserted into the auditory canal. An appropriate conduction device often has a soft tube. The tube must be fixedly connected to the earpiece so that the latter can be pulled out of the auditory canal using the tube. Nevertheless, the connection between the tube and the earpiece is made detachable by an appropriate plug so that the earpiece can be cleaned. The plug is attached as securely as possible to the soft tube. One end of the tube and a region of the plug may be encapsulated by a material by insert molding or the tube and the plug may be welded together. A method for producing a conduction device is also provided.

Abstract: A tool is provided with which a receiver of a hearing aid can be easily fitted into an earpiece or an ear mold and removed therefrom. The tool has an elongate main body, a first tool part for removing the receiver from a first earpiece, a second tool part for removing the receiver from a second earpiece, and a third tool part for fitting the receiver into the first or second earpiece. The elongate main body is divided into a first subsidiary body and a second subsidiary body). The two subsidiary bodies can be plugged at least partially one inside the other in the direction of the longitudinal axis of the main body. In addition, two of the three tool parts are arranged on one of the two subsidiary bodies, and the remaining tool part is arranged on the other of the two subsidiary bodies.

The faceplate module (106) is configured to be fitted into the receiving portion (112).

Abstract: A method operates a hearing device having at least two omnidirectional microphones emitting microphone signals and a detection unit for defining acoustic feedback. The method includes connecting a first electrical connection of the microphones to one another in order to form a first signal with directional effect, an adjustment of the directional effect of the first signal such that the acoustic feedback in the first signal is maximized, and an analysis of the first signal by the detection unit for defining the acoustic feedback. It is advantageous that the feedback can be detected by a signal with an improved signal-to-noise ratio. Feedbacks are therefore recognized more reliably and more rapidly.

Abstract: A method and device are provided for automatic, recursive adjustment of at least one hearing device worn by a person. The device includes a stimulus generator unit, which emits at least one acoustic stimulus to the hearing device, a signal detection unit with at least one sensor, which detects the neuronal activity of the brain of the person due to the acoustic stimulus, a computation and control unit, which determines a measure of listening effort from the detected neuronal activity and determines changes to hearing device parameters from this. A hearing device control unit changes the hearing device parameters accordingly. The computation and control unit repeatedly prompts the stimulus generator unit to emit a hearing stimulus and the hearing device control unit to change a hearing device parameter, until the measure of listening effort drops below a predefinable first threshold value. This allows hearing devices to be adjusted objectively and automatically in a very robust and reliable manner.

Abstract: In a hearing aid offering the option of frequency transposition, sounds should still be perceivable as sounds, even after the frequency transposition. To this end, it is proposed first of all to establish sounds present in the input signal and, more particularly, the fundamental frequencies thereof and to carry out the frequency transposition as a function of the established fundamental frequencies. Here, transposed overtones are returned to the frequency grid of the fundamental frequency, and so the sound property is maintained even after the frequency transposition.

Abstract: A hearing device that is worn in the ear has a hearing aid and a support device with a runner. The support device remains stationarily inserted in the auditory canal, while the hearing aid is moveably connected to the runner and moveably arranged along the runner. This provides for a hearing device that allows a simple, intuitively understandable modification of the volume and/or sound properties.

Abstract: A behind-the-ear hearing device has a hearing device housing and a user-operable switch. At least two microphones are disposed below the switch in the hearing device housing, and the housing is formed with first sound openings that are arranged directly below the switch. The switch is preferably a rocker switch. The microphones can be positioned below a switch in a space-saving fashion and the installation space of the hearing device housing can thus be used optimally.

Abstract: A hearing device has a first earpiece for emitting a first sound signal. The hearing device also includes a device for simulating the hearing loss of a hearing-impaired person.

The hearing device is able to simply and accurately simulate the hearing loss of a hearing-impaired hearing device wearer.
