Embodiment Construction

[0039] figure 1 The wearer 1 of the hearing device 2 is shown schematically in a top view in a conversational situation with a first interlocutor 4 and a second interlocutor 8 . The first interlocutor 4 is located in the first direction 6 with respect to the wearer 1 and the second interlocutor 8 is located in the second direction 10 with respect to the wearer 1 . Here, the second interlocutor 8 is the main interlocutor of the wearer 1, and the first interlocutor 4 participates in this conversation only through sporadic speech contributions. Here, for figure 1 The images above and below describe the same dialogue situation.

[0040] Now, in order to moderate the level peaks (Pegelspitzen) of the speech contributions of the first interlocutor 4 and the second interlocutor 8 for the wearer 1 of the hearing device 2 in the output sound signal of the hearing device 2, now, as in figure 1 As shown in the upper image of , the first calibrated directional signal 12 is first genera...

Abstract

The invention relates to a method for directional signal processing for a hearing instrument, wherein a first input signal is generated from an ambient sound signal, wherein a second input signal is generated from an ambient sound signal, wherein a first and a second input signal are generated The two input signals generate a first calibrated orientation signal having relative attenuation in the direction of the first useful signal source of the environment, wherein, based on the first and second input signals, a second calibrated orientation signal is generated, the second calibrated orientation signal at There is a relative attenuation in the direction of the second useful signal source of the environment, wherein a relative amplification parameter is determined from the first and second calibration directional signals, wherein the first and second processing are generated from the first and second input signals, respectively A directional signal, wherein a source sensitive directional signal is generated from the first processed directional signal, the second processed directional signal and the relative amplification parameter, and wherein an output signal of the hearing device 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 by a first input converter of the hearing device as a function of an ambient sound signal, wherein a second input converter of the hearing device is used to generate a first input signal a device that generates a second input signal based on the acoustic signal of the environment, wherein based on the first input signal and based on 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 with a relative attenuation, wherein a second directional signal is generated as a function of the first input signal and as a function of the second input signal, the second directional signal has a relative attenuation in the direction of the second useful signal source of the environment, wherein as a function of the first orient...
