Noise is the form of unwanted signal which attenuate the flow of information signal. So some techniques are used to avoid noise. Noise cancellation technology is aimed at reducing unwanted ambient sound. Adaptive filtering plays an important role in the field of signal processing and has various applications in fields of speech processing & communications. In signal processing, the function of a filter is to remove unwanted parts of the signal, such as random noise, or to extract useful parts of the signal, such as the components lying within a certain frequency range. In the process of transmission of information from the source to receiver side, noise from the surroundings automatically gets added to the signal. This acoustic noise picked up by microphone is undesirable, as it reduces the perceived quality or intelligibility of the audio signal. The problem of effective removal or reduction of noise is an active area of research.
