Abstract
A microphone system including a first sensor configured to output a first signal based on an ambient sound relative to a recipient of the system, a second sensor configured to output a second signal corresponding to a noise reference, and first signal processing circuitry configured to process the first signal based on the second signal and output a third signal based on the processed first signal, wherein the system is configured to limit a gain of the third signal based on the presence of impulsive energy in the second signal.
