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 a hearing instrument having an acousto-electric first input transducer and an electro-acoustic output transducer. A first input signal is generated by the first input transducer from an ambient sound. The first input signal and/or a first intermediate signal derived from the first input signal is resolved into a multiplicity of frequency bands. An output signal is generated from the first input signal, or from the first intermediate signal, by frequency-selective signal processing. A relevant subset of frequency bands is determined from the aforementioned multiplicity such that, in each frequency band of the relevant subset, an output sound generated from the output signal by the output transducer makes a contribution that lies above a predefined or desired threshold, further, with the aid of signal components of the first input signal, or of the first intermediate signal.

Abstract: In a method for operation of a docking arrangement, position information is determined that describes a position of the patient table, including detecting, sensor data corresponding to: the position of the patient table relative to the docking arrangement, and/or to an environment feature describing a movement trajectory to the docking arrangement.

In the assistance operating mode, at least one guidance measure may be determined for the patient table and a functional component of the patient table may be controlled to assist the operator.

Abstract: A method for localizing a sound source for a binaural hearing system with first and second hearing instruments. First and second input signals are formed from an ambient sound signal and directional signals are formed by directional signal processing of the input signals. The directional signals have a minimum sensitivity in different minimum directions with respect to a preferred direction of the binaural hearing system. Based on the directional signals, first and second source directions of the sound source are determined starting from the first and second hearing instrument, respectively. Based on the source directions and a distance between the first and second hearing instruments, the distance of said sound source from a reference point of the binaural hearing system and a main direction of the said sound source are determined to thereby localize the sound source.
