MICROPHONE ARRANGEMENT

A microphone arrangement comprises a microphone array (20) comprising at least two microphones (202, 204), each of the at least two microphones (202, 204) providing a microphone output signal (s1[n], s2[n]), a first adder (302), configured to provide a microphone array output signal (sb[n]) by summi...

Beschreibung
Zusammenfassung:	A microphone arrangement comprises a microphone array (20) comprising at least two microphones (202, 204), each of the at least two microphones (202, 204) providing a microphone output signal (s1[n], s2[n]), a first adder (302), configured to provide a microphone array output signal (sb[n]) by summing delayed versions (s1[n-d1], s2[n]) of the microphone output signals (s1[n], s2[n]) of each of the at least two microphones (202, 204), a first filter unit (402), configured to provide a filtered microphone array output signal (s'b[n]), a second filter unit (404) configured to provide a filtered microphone output signal (s'2[n]) of one of the at least two microphones (202, 204), and a second adder (304), configured to provide an output microphone signal (out[n]) by summing the filtered microphone array output signal (s'b[n]) and the filtered microphone output signal (s'2[n]).
