Method of rejecting inherent noise of a microphone arrangement, and hearing device

A method of rejecting inherent noise of a microphone arrangement having a first microphone and a second microphone, the method comprising:

• generating with the first microphone a first microphone signal from a sound signal from the surroundings;
• generating with the second microphone a second microphone signal from the sound signal from the surroundings;
• ascertaining a measure of correlation between the first microphone signal and the second microphone signal;
• rejecting inherent noise of at least one of the first microphone or the second microphone in the first or second microphone signal on a basis of the measure of correlation;
• and
• ascertaining at least one parameter selected from the group consisting of a wanted signal level, a power spectral density, a noise level, and a noise power variable for the first microphone signal and/or for the second microphone signal;
• and
• additionally controlling a rejection of the inherent noise of the microphone arrangement on a basis of at least one of the signal parameters, and rejecting the inherent noise of the microphone arrangement by way of Wiener filter;
• using the wanted signal level and/or the power spectral density or using the noise level and the noise power variable as input variables for the Wiener filter;
• and
• applying the Wiener filter to at least one of the first microphone signal or the second microphone signal in dependence on the measure of correlation.
