Abstract: A method trains a speaker recognition unit of a hearing aid of a user, wherein the hearing aid is connected to a communication device of the user, for carrying out a remote conversation between the user of the hearing aid and a conversation partner of the user. An audio signal of the conversation partner is received by the communication device for output to the user. A speaker ID is assigned to the conversation partner, wherein a number of speech samples of the conversation partner is extracted from the audio signal. The speech samples are assigned to the speaker ID and form a training data set jointly therewith. The speaker recognition unit of the hearing aid is trained using the training data set in order to recognize the conversation partner in future.

Abstract: A method operates a hearing aid, in particular a classic hearing aid. The hearing aid includes an input transducer, a signal processing device, and an output transducer. Wherein an occurrence of a comb filter effect is determined by the signal processing device, and wherein a countermeasure is controlled by the signal processing device as a function of the determined occurrence of the comb filter effect.

Abstract: A method fits a digital hearing aid having an input transducer, a signal processing device and an output transducer. The signal processing device is configured to form an evaluation unit, a comparator unit, and a pre-amplification unit. An acoustic test signal is generated by an external testing device while the hearing aid is worn by a hearing-aid wearer. A digital test input signal is generated by the input transducer on the basis of the acoustic test signal. A sound pressure-dependent test quantity is determined on the basis of the digital test input signal by the evaluation unit. A deviation between the sound pressure-dependent test quantity and a reference quantity stored in the signal processing device is determined by the comparator unit. A pre-amplification by the pre-amplification unit is adjusted on the basis of the determined deviation.

Abstract: A method operates an apparatus for tinnitus characterization, in which, in a first step, a broadband test signal having a number of signal frequencies is generated and compared with a tinnitus noise. The respective test signal is stored with an associated comparison result. A probability correlation for determining the tinnitus noise is established based on the stored test signals and comparison results. In a second step, the amplitudes of the individual signal frequencies of the test signal are varied. The first and second steps are performed repeatedly until the probability correlation reaches or exceeds a first threshold value. In a third step, the amplitudes of the individual signal frequencies of the test signal are varied with reference to the probability correlation.

Abstract: A method for recognizing a beat for a hearing system includes converting an acoustic input signal into an electrical input signal in an input transducer. The electrical input signal is processed into an electrical output signal in a signal processing unit. The electrical output signal is converted into an output signal in an output transducer. A beat is recognized by analyzing the electrical input signal and the recognized beat is perceivably output to a hearing system user. A corresponding hearing system for recognizing a beat in the input signal and outputting the recognized beat in a perceivable manner is also provided.

Abstract: A hearing aid has an acoustoelectric transducer, a pickup device for picking up an electrical or electromagnetic signal and converting it into an electrical signal. The hearing aid further has a signal processing device, an electromechanical transducer for outputting an acoustic signal, and a signal estimation device. The signal estimation device determines a correlation between signals of the acoustoelectric transducer and of the pickup device. The signal processing device adjusts a mixing ratio of the signals in the output signal depending on the correlation.

Abstract: A hearing aid device has a directional microphone system with a first microphone outputting a first microphone signal and a second microphone outputting a second microphone signal. A delay unit generates a directivity by delaying the second microphone signal or a fourth microphone signal derived therefrom by an internal time delay and associating it with the first microphone signal or a third microphone signal derived therefrom for generating a directional microphone signal. A cross-correlation analysis unit receives the first or the third microphone signal and the second or the fourth microphone signal and determines a value of a cross correlation of the two microphone signals. A control unit adjusting the time delay depending on the value of the cross correlation of the two microphone signals. A classifier determines audio conditions in which the hearing aid device is currently situated, and the time delay is adjusted depending on the audio conditions.

Abstract: The adjustment of a hearing device is to be improved and configured in a more user-friendly fashion. To this end, a method is proposed whereby the hearing device is set individually to the user and is inserted at least partially into the auditory canal of the user. Finally an in-situ measurement of the acoustic impedance of the auditory system of the user including at least part of the auditory canal of the user is implemented with a tympanometric method. An automatic correction of the individual setting of the hearing device can take place on the basis of the results of the in-situ measurement.

Abstract: A magnetofluidic hearing aid system includes a hearing aid having a signal processing device connected to a magnetic transmitter. The system includes such a hearing aid and a magnetofluid suitable for use in the body. The magnetic transmitter transmits a magnetic field producing vibrations in a liquid mixture containing the magnetofluid. The liquid mixture is operatively introduced into a cochlea, and the vibrations are suitable for triggering an auditory perception in the cochlea. Acoustic feedback is precluded as a result of the transmitter producing neither acoustic signals nor mechanical vibrations. A functional impairment caused by physical influences such as soiling, for example, of an acoustic receiver, is also precluded. Problems arising from impaired contact with the body are prevented from the beginning by the non-contact signal transmission. A hearing aid supply is also advantageously enabled regardless of the functional capability of the middle ear apparatus.

Abstract: An apparatus and an associated method for improving the signal-to-noise ratio of a measuring signal emitted and detected by a hearing device include a generator unit for generating a measuring signal, a modulation unit for modulating the measuring signal prior to or during emission in such a way that the detected measuring signal is modulated according to the generated measuring signal, and a detection unit for detecting the measuring signal on the basis of the modulation. The result of a measurement, for instance an OLG measurement, is therefore more independent of external disturbances and the signal-to-noise ratio is increased.
