Abstract
Technology described in this document can be embodied in a method that includes receiving a first input signal captured by at least a first feedforward microphone associated with an active noise reduction (ANR) device, receiving a second input signal captured by at least a second feedforward microphone associated with the ANR device, processing the first input signal using a first filter disposed in a first ANR signal flow path to generate a first output signal for an acoustic transducer of the ANR device, processing the second input signal using a second filter disposed in a second ANR signal flow path to generate a second output signal for the acoustic transducer, in which the second filter is different from the first filter, and generating a combined signal for the acoustic transducer based on combining the first output signal with the second output signal.
