Abstract: A device for filtering electrical signals has a number of inputs (2L, 2R) arranged spatially at a distance from one another and supplying respective pluralities of input signal samples. A number of signal processing channels (10L, 10R), each formed by a neuro-fuzzy filter, receive a respective plurality of input signal samples and generate a respective plurality of reconstructed samples. An adder (11) receives the pluralities of reconstructed samples and adds them up, supplying a plurality of filtered signal samples. In this way, noise components are shorted. When activated by an acoustic scenario change recognition unit (5), a training unit (4) calculates the weights of the neuro-fuzzy filters, optimizing them with respect to the existing noise.
