Abstract:
1. A method of operating a microphone system for processing an incident audio signal, the method comprising: providing a first microphone having a first dynamic range, wherein the first dynamic range has a first noise floor and a first top-end; providing a second microphone having a second dynamic range, wherein the second dynamic range has a second noise floor and a second top-end, and wherein the first noise floor is less than the second noise floor, the second top-end is greater than the first top end, and wherein the first dynamic range overlaps the second dynamic range; producing a first signal using the first microphone, and multiplying the first signal by a first weighting factor to produce a first weighted output signal; producing a second signal using the second microphone, and multiplying the second signal by a second weighting factor to produce a second weighted output signal; summing the first weighted output signal and the second weighted transducer output signal; and
