Problems solved by technology

If the wearer of the hearing device is in a complex hearing situation, for example in a conversation with several conversation partners, then one conversation partner may, for example, trigger a compression due to a short scream or a loud laugh, thereby significantly reducing the hearing capacity of the other conversation participants. dialogue contribution, which affects the wearer's intelligibility

Embodiment Construction

[0093] figure 1 A top view schematically shows a wearer 1 of a hearing device 2 in a conversation situation with a first conversation partner 4 and a second conversation partner 8 . The first conversation partner 4 is positioned in a first direction 6 with respect to the wearer 1 and the second conversation partner 8 is positioned in a second direction 10 with respect to the wearer 1 . The first conversation partner 4 is here the main conversation partner of the wearer 1 , the second conversation partner 8 takes part in the conversation only by means of individual linguistic contributions. The dialog situation described here is for figure 1 The above and below figures are the same. Language Contribution of the First Dialogue Partner 4 In this case, a first useful signal S1 is formed, and the speech contribution of the second conversation partner 8 forms a second useful signal S2 .

[0094] Now in order to reduce the level peaks of the first useful signal S1 and the second...

Abstract

The invention relates to a method for directional signal processing for a hearing aid, which includes generating first and second input signals from an ambient sound signal using first and second input transducers of the hearing aid; forming first and second directional signals based on the first and second input signals, the second directional signal having relative attenuation in directions of a first useful signal source, the first directional signal having relative attenuation in directions of a second useful signal source; ascertaining first and second amplification parameters; defining a reference directional characteristic; as a function of the reference directional characteristic, ascertaining corrected first and second amplification parameters so that an output directional signal, formed as a sum of the first directional signal weighted by using the first corrected first amplification parameter and the second directional signal weighted by using the corrected second amplification parameter, merges into a linearly scaled reference directional signal upon the first amplification parameter being equal to the second amplification parameter.

Description

technical field [0001] The invention relates to a method for directional signal processing (direktionaleSignalverarbeitung) of a hearing device, wherein a first input signal is generated from a sound signal of the environment via a first input converter of the hearing device, wherein via a second input of the hearing device The converter generates a second input signal from the sound signal of the environment, wherein a first direction signal and a second direction signal are respectively formed according to the first input signal and the second input signal, wherein the second direction signal follows the direction of the first useful signal source The direction (or the direction towards the first useful signal source) has a relative attenuation, wherein the first direction signal has a relative attenuation in the direction of the second useful signal source, and wherein the first signal used to amplify the first useful signal source is determined. A first amplification param...
