Techniques for reducing noise in an ever-increasingly noisy world are essential. It is the purpose of this paper to review and demonstrate the efficacy of active noise cancellation in speech signals. Acoustic noise reduction is used in industrial, manufacturing, and consumer products, such as mobile phones. -Adaptive filtering, zero frequency filtering, and its advantages and disadvantages are all included here. Other than what's already been mentioned and put to the test with a noisy signal, an effective approach is developed and the results are reported.
