ABSTRACT:
A method for locating signal sources, particularly sound signal sources, is suggested using several spacially separated sensors whose output signals are processed in order to detect noise and to eliminate such noise under utilization of a normalizing factor, the normalizing factor considers particularly those frequencies which, for one reason or another, are uniquely attributable to noise.
