Embodiment Construction

[0028] figure 1 Method 2 for operating hearing aid 4 is shown schematically in a block diagram. The hearing aid 4 has a first input converter 6 and a second input converter 8 , which generate a first input signal 12 or a second input signal 14 from an ambient sound signal 10 . The first input converter 6 and the second input converter 8 are in each case designed as omnidirectional microphones. In a preprocessing step 16 , a first directional signal 18 and a second directional signal 20 are now generated as intermediate signals from the first input signal 12 and the second input signal 14 . In this case, the first directional signal 18 has a directional characteristic 22 which is given by a cardioid whose preferred direction 24 extends along an axis 25 which is formed by the two input converters 6 , 8 . The second directional signal 20 has a directional characteristic 26 complementary to the first directional signal 18 , which is given by an inverse cardioid with respect to a...

Abstract

The invention relates to a method (2) for operating a hearing aid (4), wherein a first input signal (12) is generated from a sound signal (10) by a first input converter (6), wherein a second input converter (8) generating a second input signal (14) from the sound signal, wherein a first angle and an angle range are preset wherein an attenuation directional signal (28) is formed according to the frequency band by means of the first input signal, the second input signal and the first angle, which having a relative attenuation at least for a second angle in an angular range around the first angle, and thereby determining superposition parameters, by means of the first and second input signals and the superposition parameters and / or the second angle forming an amplified directional signal ( 34) having relative amplification for a second angle, generating an angled directional signal (40) from the attenuated directional signal and the amplified directional signal, and generating an output signal (50) with the angled directional signal.

Description

technical field [0001] The invention relates to a method for operating a hearing aid, wherein a first input signal is generated from a sound signal by a first input converter, wherein a second input signal is generated from the sound signal by a second input converter, wherein according to the An input signal, a second input signal form an amplified directional signal, and wherein an output signal is generated from the amplified directional signal. Background technique [0002] In a hearing aid, the sound signal of the environment is converted into a corresponding electrical signal by means of one or more input converters, the electrical signal is also amplified depending on the frequency band in order to correct the hearing loss of the user of the hearing aid, and the thus amplified signal is passed through the output The converter is converted into an output sound signal, and the output sound signal is output to the user's ear. Here, the two basic tasks of the hearing aid...
