Abstract
Systems and methods for cancelling a near-field noise signal. The methods generally involve: receiving (), from a first acoustic sensing device (), a first signal () comprising a near-field noise signal (); synthesizing () a replica signal () which replicates the near-field noise signal; and communicating () the replica signal and the first signal to a far-field noise cancellation process (). Prior to communicating the replica signal to the far-field noise cancellation process, at least one characteristic of the replica signal is controlled () so that the far-field noise cancellation process will identify the near-field noise signal as far-field noise. The far-field noise cancellation process cancels () the near-field noise signal and generates () an output signal () in which the near-field noise signal is reduced in amplitude.
