Abstract (en)
[origin: EP1458216A2] The system has two microphone input signals, Mic In (2) and Ref Mic (7). The signals are fed to first (1) and second (5) microphones with given transmission functions (s/s-pol-ac1) and (s/s- pol-ac2). The output of the first microphone goes to a compensation filter (3') with a transmission function dependent on the first two transmission functions (s-pol-ac1/s-pol-ac2). The output from this filter goes to a first output Out Mic 1 (4). The output of the second microphone goes to a second output Out Mic 2 (8).
