Abstract: A hearing device has an input transducer, a signal processor for signal amplification and generation of an output signal, and an output transducer for converting the output signal into a sound signal. In a fitting method for fitting the hearing device, at least one test measurement is carried out in which a test signal is generated as an acoustic signal, and in which the hearing device user assesses the resulting sound signal as a test result. A fitting formula is determined based on the test result, and the signal processing device is set based on the fitting formula such that if, during operation of the hearing device, a rise time of a signal start of the input signal is less than or equal to a stored threshold value, then the signal start of the output signal is amplified by a higher gain value than the remaining output signal.

Abstract: A method operates a hearing aid which is allocated to a user. The hearing aid receives an audio signal and generates an input signal. From the input signal an automatic gain control (AGC) input signal is generated and is supplied to an AGC unit of the hearing aid. The AGC unit amplifies the AGC input signal depending on a level of the AGC input signal and in accordance with an AGC function and then outputs it as an AGC output signal. The AGC function is defined by one or more parameters which are set depending on an acoustic scene which is currently present. The hearing aid generates, from the AGC output signal, an output signal for output to the user. A hearing device is programmed to perform the method.

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: A method for directional signal processing for a binaural hearing system. In input transducers of first and second hearing instruments generate input signals from an ambient sound signal. A direction relative to a preferred direction and a distance from a reference point of the binaural hearing system are predetermined, to predetermine a focal point. First and second directional signals are generated from input signals by directional signal processing so that a direction of maximum sensitivity, starting from the first and second hearing instruments form respective a first and second yaw angles with the preferred direction. The yaw angles are adjusted via the directional signal processing of the input signals so that a superposition of the first and second directional signals has a maximum sensitivity in an overlap region that includes the predetermined focal point. An output signal of the binaural hearing system is generated based on the superposition.
