Abstract :
Active noise control (ANC) grabbed the research community´s attention during the last half of the 20th Century; however, technological and computational limitations prevented any ANC algorithms from widespread use. Such is no longer the case. In this paper, the author describes how advances in computer and digital signal processing technology along with the relatively low cost of such hardware have facilitated their widespread use in the noise control of confined spaces
