MULTI-MICROPHONE SYSTEM AND METHOD

Provided herein are a multi-microphone system and method including a controller, a plurality of transducers each operable within a unique sensitivity range, and corresponding microphone units. The controller receives a sound signal output from a first microphone unit that corresponds to a microphone unit having a transducer with the highest sensitivity. The controller analyzes the sound signal output to identify a first parameter of the sound signal output and determines if the first parameter satisfies pre-defined criteria. In an instance in which the first parameter satisfies the pre-defined criteria, the controller outputs the sound signal output of the selected first microphone unit as the output of the multi-microphone system. Otherwise, the controller receives a sound signal output from a second microphone unit comprising a corresponding transducer with a sensitivity less than the first microphone unit but greater than remaining transducers.
