Abstract : In an increasingly noisy environment, methods of eliminating noise are becoming more important. The objective of this paper is to present a comprehensive coverage of available literature on the techniques used for active noise cancellation in speech signals and to showcase the performance of one such effective method. Acoustic noise cancellation has applications in wide variety of problems in industrial operations, manufacturing and consumer products including mobile phones. This paper reviews the recent developments in noise cancellation which includes the principle, adaptive filter algorithms, zero frequency filtering technique and their advantages and limitations. In addition to the above mentioned wide concepts, one such efficient method is implemented and experimented with a noisy signal and the results are also discussed in this paper. Keywords—Active Noise cancellation, Acoustic Noise Cancellation, Adaptive filters, Zero frequency filtering, Resonator.
