Abstract (en)

Method of enhancing the provision of feedforward-based ANR to both ears of a user of a personal ANR device having a first earpiece and a second earpiece, the method comprising: disposing a first feedforward microphone on the first earpiece; disposing a first acoustic driver within the first earpiece; disposing a second feedforward microphone on the second earpiece; disposing a second acoustic driver within the second earpiece; and employing both first feedforward reference sounds detected by the first feedforward microphone and second feedforward reference sounds detected by the second feedforward microphone in deriving both first feedforward anti-noise sounds to be acoustically output by the first acoustic driver and second feedforward anti-noise sounds to be acoustically output by the second acoustic driver.
