    摘要: A method for directional signal processing for an acoustic system, wherein first and second input transducers generate a first and a second input signal from an ambient sound. First and second intermediate signals are generated from the first and second input signal, wherein a preliminary superposition parameter is obtained for a first superposition of the first intermediate signal and the second intermediate signal in such a way that for the first superposition an attenuation in a first target direction has a maximum. A superposition parameter is formed from the preliminary superposition parameter so that a second superposition of the first and second intermediate signals, formed in the first target direction with the superposition parameter, has a pre-specified first value for a gain that is greater than zero. An output signal of the acoustic system is formed from the second superposition.

    摘要: A method for directional signal processing for a hearing aid. First and second input transducers generate first and second input signals from an ambient acoustic signal. A forward signal and a backward signal are generated from the first and second input signals and a first directional parameter is determined as a linear factor of a linear combination of the forward and backward signals. The first directional signal has a maximum attenuation in a first direction. A correction parameter is ascertained such that a second directional signal has a defined relative attenuation in the first direction. The second directional signal is generated from the forward signal and the backward signal with the first directional parameter and the correction parameter or with the first directional signal and the omnidirectional signal based on the correction parameter. An output signal of the hearing aid is generated based on the second directional signal.

    摘要: A hearing system contains a hearing instrument and the hearing instrument is configured to support the hearing of a hearing-impaired user. The hearing instrument is operated via an operating method. The method includes capturing a sound signal from an environment of the hearing instrument, processing the captured sound signal to at least partially compensate the hearing-impairment of the user and outputting the processed sound signal to the user. The captured sound signal is analyzed to recognize speech intervals, in which the captured sound signal contains speech. During recognized speech intervals, at least one time derivative of an amplitude and/or a pitch of the captured sound signal is determined. The amplitude of the processed sound signal is temporarily increased, if the at least one derivative fulfills a predefined criterion.

    摘要: A method for operating a hearing device. In the hearing device a first directional signal and a second directional signal are generated from an ambient sound signal. The first directional signal and the second directional signal are used to determine at a first response time a first adaptation coefficient for a first superposition of the first directional signal with the second directional signal for the purpose of noise suppression. It is intended here that the first directional signal and the second directional signal are used to determine at a second response time a second adaptation coefficient for a second superposition of the first directional signal with the second directional signal for the purpose of noise suppression. The first adaptation coefficient and the second adaptation coefficient are used to determine an output adaptation coefficient for forming an output signal by superposition of the first directional signal and the second directional signal.

    摘要: A hearing aid system has at least two hearing aid devices to be worn on both sides of a wearer's head. The hearing aid devices have a transducer for picking up an acoustic signal and converting same into a first audio signal in each case. A signal processing unit processes audio signals received from each hearing aid device through a signal connection. The signal processing unit evaluates a signal component from a preferred direction in relation to the head of the wearer in the first audio signals. By way of the first audio signals the signal processing unit generates a first binaural directional microphone signal and adjusts its directional characteristic as a function of the evaluation.

    摘要: A method for directional signal processing of signals of a microphone array, including first and second microphones generating first and second input signals from an ambient sound, uses the first input signal to form a reference signal transformed into the frequency domain, thereby generating a frequency-space reference signal. The first and second input signals are transformed into the frequency domain, and a first frequency-space directional signal is formed in the frequency domain using the transformed first and second input signals. A frequency-resolved comparison of the frequency-space reference signal with the first frequency-space directional signal or signal derived therefrom in the frequency domain, is used to generate frequency-dependent first gain factors to generate a time filter in the time domain. The reference signal is filtered by the time filter and an output signal is generated from the reference signal filtered by the time filter.
