Embodiment Construction

[0039] figure 1 A top view schematically shows a wearer 1 of a hearing device 2 in a conversation situation with a first interlocutor 4 and a second interlocutor 8 . The first interlocutor 4 is located in a first direction 6 relative to the wearer 1 and the second interlocutor 8 is located in a second direction 10 relative to the wearer 1 . Here, the second interlocutor 8 is the main interlocutor of the wearer 1 , the first interlocutor 4 taking part in the conversation only by sporadic speech contributions. Here, for figure 1 The images above and below the , depict the same conversation situation.

[0040] Now, for the wearer 1 of the hearing device 2 in the output sound signal of the hearing device 2, the level peaks (Pegelspitzen) of the speech contributions of the first interlocutor 4 and the second interlocutor 8 are moderated, now, as in figure 1 As shown in the upper image of , first by means of an adaptive directional microphone, a first calibrated directional signa...

Abstract

A method performs directional signal processing for a hearing aid. First and second input transducers of the hearing aid generate first and second input signals, respectively, from a sound signal. A first calibration directional signal which has a relative attenuation in the direction of a first useful signal source is generated from the first and second input signals, and a second calibration directional signal which has a relative attenuation in the direction of a second useful signal source is generated from the first and second input signals. A relative gain parameter is determined from the first and second calibration directional signals. First and second processing directional signals are generated from both the first and second input signals. A source-sensitive directional signal isgenerated from the first and second processing directional signals and the relative gain parameter. An output signal of the hearing aid is generated from the source-sensitive directional signal.

Description

technical field [0001] The invention relates to a method for directional signal processing for a hearing device, wherein a first input signal is generated from an ambient sound signal via a first input converter of the hearing device, wherein a second input converter of the hearing device The device generates a second input signal according to the sound signal of the environment, wherein, according to the first input signal and according to the second input signal, a first directional signal is generated, the first directional signal is in the direction of the first useful signal source of the environment having a relative attenuation, wherein a second directional signal is generated from the first input signal and from the second input signal, the second directional signal having a relative attenuation in the direction of a second useful signal source of the environment, wherein according to the first directional signal, a second directional signal, and a relative amplificati...
