METHOD FOR PROVIDING THE TRANSMISSION CHARACTERISTICS OF A MICROPHONE ARRANGEMENT AND MICROPHONE ARRANGEMENT

摘要

Two output signals (A1a and A1b) of a microphone arrangement (1) are divided (7), whereby said signals are differently dependent on the direction of incidence ( phi ) of acoustic signals. A product from the division result (A7) and the weighting factor ( alpha ) is saturated (12) and subtracted from a signal value (A) which can be inputted. The subtraction result is multiplied with the output signal of the microphone arrangement (1) which is the denominator signal for the division (7). A desired directivity is produced between the result signal (Sout) of the multiplication and the direction of incidence ( phi ) on the microphone arrangement (1) of incident acoustic signals according to the weighting factor ( alpha ) of the saturation value (B) and of the subtraction value (A).
