Finally, open issues and theįuture of ANC in the era of artificial intelligence are discussed. Non-stationary and/or broadband noise, as well as the commercial transitionĬhallenges from analog to digital ANC systems.
This article focuses on technicalĭevelopments pertaining to real-world implementations, such as improvingĪlgorithmic convergence, reducing system latency, and extending control to This article continues where Elliott and Nelson'sġ993 Signal Processing Magazine article and Elliott's 1997 50th anniversaryĬommentary~\cite on ANC left off, tracing the technicalĭevelopments and applications in ANC spurred by the seminal texts of Nelson andĮlliott (1991), Kuo and Morgan (1996), Hansen and Snyder (1996), and Elliott The widespread commercial success of ANC in aircraft cabins,Īutomobile cabins, and headsets demonstrates the immeasurable public health andĮconomic benefits of ANC. Early theoreticalĪdvancements in digital signal processing and processors laid the groundworkįor the phenomenal growth of the field, particularly over the past Of sound, the field of active noise control (ANC) has not flourished until theĪdvent of digital signal processors forty years ago. This repo contains the ENF-WHU audio recording dataset collected around Wuhan University campus and the MATLAB programs for electronic network frequency (ENF) detection, enhancement, and robust estimation, in ENF-based audio forensic applications.
