Abstract
Technology described in this document can be embodied in an earpiece of an active noise reduction (ANR) device. The earpiece includes a plurality of microphones, wherein each of the plurality of microphones is usable for capturing ambient audio to generate input signals for both an ANR mode of operation and a hear-through mode of operation of the ANR device. The earpiece further includes a controller configured to: process a first subset of microphones from the plurality of microphones to generate input signals for the ANR mode of operation and process a second subset of microphones from the plurality of microphones to generate input signals for the hear-through mode of operation. The second subset of microphones excludes a first microphone from the plurality of microphones located closest to a noise pathway of the earpiece.
