Abstract: Technology described in this document can be embodied in a method that includes receiving a first input signal representing audio captured by a first sensor disposed in a signal path of an active noise reduction (ANR) device, and receiving a second input signal representing audio captured by a second sensor disposed in the signal path of the ANR device. The method also includes processing, by at least one compensator, the first input signal and the second input signal to generate a drive signal for an acoustic transducer of the ANR device. A gain applied to the signal path is at least 3 dB less relative to an ANR signal path having a single sensor.

Abstract: This document describes a method that includes receiving an input signal representing audio captured by a sensor disposed in an active noise reduction (ANR) device, determining, by one or more processing devices, that the ANR device is operating in a first operational mode, and in response, applying a first gain to the input signal to generate a first amplified input signal. The method also includes determining, by the one or more processing devices, that the ANR device is operating in a second operational mode different from the first operational mode, and in response, applying a second gain to the input signal to generate a second amplified input signal, wherein the second gain is different from the first gain. The method further includes processing the first or second amplified input signal to generate an output signal, and generating, by an acoustic transducer, an audio output based on the output signal.

Abstract: An active noise reduction (ANR) device includes a first sensor configured to generate an input signal indicative of an environment of the active noise reduction device, in which the first sensor has a measured roll-off frequency. A first compensator processes the input signal to generate a compensated input signal to compensate a difference between the measured roll-off frequency and a predetermined roll-off frequency for the first sensor. A second compensator processes the compensated input signal to generate a first signal for an acoustic transducer of the active noise reduction headphone.
