Dh. Crawford et al., DIGITAL SIGNAL-PROCESSING STRATEGIES FOR ACTIVE NOISE-CONTROL, Electronics & communication engineering journal, 9(2), 1997, pp. 81-89
Over the last few years the increase in processing power available fro
m digital signal processors has allowed active noise control to become
a viable real-world technology. This paper reports on the development
of a two channel active noise controller using low-cost DSP technolog
y and presents illustrative results for a variety of real-world applic
ations.
