(57) Abstract The microphone device (1) the signal of two outputs (A_1a and A_1b) differs, following to the incident direction () of the sound signaling, mutually. The product of the division result (A₇) and the weight factor () due to the division (7) between both signals to be saturated (12) the te, subtraction is done from the input signal (A). The subtraction result is multiplied the microphone device as a denominator signal of division (7) (1) the output signal. Saturation value (B) weight factor () and according to subtraction value (A), the multiplication result signal (S _out) and in the microphone device (1) directional characteristics of desire are created with incident direction () of the sound signaling.
