The method involves detecting acoustic signals with two microphones (MIK1,MIK2) at a defined distance (d) apart, separating the signals of one sound source (S1,S2) from the others based on the microphone signals by Fourier transformation of the microphone signals, determining the phase difference between the microphone signals for each frequency component of their frequency spectra, determining the angle of incidence of each acoustic signal based on the phase difference and frequency, generating a signal spectrum using a filters function and inverse Fourier transformation of the signal spectrum. The filter function is dependent on the angle of incidence (upsilon) with a maximum at the preferred angle and is combined with a frequency spectrum by multiplication. - AN INDEPENDENT CLAIM is also included for a device for implementing the inventive method. |
