Patent ID: 8675884

Claim:
A system for processing sound, the system comprising: 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 a communication interface, configured to provide the corrected signal to an external system; wherein the processor is further configured to determine the corrected signal Ŝ(n) for the detection moment n, by a sum of convolutions Ŝ(n)=h 1 (n)*M 1 (n)+h 2 (n)*M 2 (n)+h 3 (n)*M 3 (n), wherein M 1 (n) represents the first input signal at the detection moment, M 2 (n) represents the second input signal at the detection moment, M 3 (n) represents the third input signal at the detection moment, and h 1 (n), h 2 (n), and h 3 (n) are calibration functions.
