“…At the moment, there are already known ways to reduce the computational cost and implement noise cancelling in frequency domain (e.g., using the Fourier window transform) [12] [13]. There is also an algorithm of active noise control of sound fields at discrete components of the signal spectra, which does not require real-time signal processing [14].…”

When building an adaptive noise cancellation system for wideband acoustic signals, one can meet some difficulties in practical implementation of such a system. The major problem is related to the necessity of using real-time signal generation and processing. In this paper the active noise control system which utilizes adaptation in frequency domain is considered. It is shown that the proposed algorithms simplify practical implementation of a noise cancellation system. The results of computer simulations and prototype experiments show the effectiveness of the proposed methods.
