A method for the suppression of at least one acoustic interference signal and apparatus for carrying out the method

摘要

A method for the suppression of at least one acoustic interference signal (as3, as4) with a directional microphone system (rms, rm1, rm2), the at least two microphones (m1, .. M5), with the following method features:– Generating a plurality of directional microphone signals (rms1, rms2) by means of weighted combination of signals of the at least two microphones (m1, .. M5), wherein the weighting in each case a directional sensitivity of the directional microphone system (rms, rm1, rm2), determined,– Normalizing the directional microphone of the signals (rms1, rms2) to the same sensitivity of the directional microphone system (rms, rm1, rm2) in a range,– Selecting the directional microphone signal (rms1, rms2) with the smallest interference signal component as the output directional microphone of the signal (arm, arms1, arms2).
