US Patent 8675884 Method and a system for processing signals

A system for processing sound, the system including: (a) a processor, configured to process a first input signal that is detected by a first microphone at a detection moment, a second input signal that is detected by a second microphone at the detection moment, and a third input signal that is detected by a bone-conduction microphone at the detection moment, to generate a corrected signal that is responsive to the first, second, and third input signals; and (b) a communication interface, configured to provide the corrected signal to an external system.
