Abstract:
1. A microphone system comprising: a primary microphone for producing a primary signal and having a primary diaphragm and a first air leakage rate past the primary diaphragm; a secondary microphone for producing a secondary signal and having a secondary diaphragm and a second air leakage rate past the secondary diaphragm, the first air leakage rate and second air leakage rate being different; a selector operatively coupled with the primary microphone and the secondary microphone; a base mechanically coupling the primary and secondary microphones such that the primary and the secondary microphones receive the same mechanical signals; and an output, the selector selectively permitting one or both of at least a portion of the primary signal and at least a portion of the secondary signal to be forwarded to the output as a function of the noise in the primary signal.
