ABSTRACT:
In order to locate electromagnetic or acoustic signal sources of a sensor configuration (1athrough1c) fitted with at least two electric outputs; where the incidence-dependent transfer functions between the acoustic signals incident on the input(s) of the sensor configuration (1athrough1c) and the electric output signals are different, the ratio (7xthrough7xx) of the output signal is formed and the result then is correlated with the previously determined ratio function (11).
