Real-Time Application of Active Noise Cancellation for Security of Human Life and Property in concern with social well being

Active noise cancellation is the process of suppression of narrowband interference from a wideband signal using adaptive filtering techniques. There are several advantages of active noise cancellation over conventional passive noise cancellation techniques. Such advantages make active noise cancellation applicable to a wide range of problems and challenges posed in various real-time environments. This paper emphasizes the application of ANC on real-time problems and proposes different models for such applications where ANC can prove to be a better option as compared to passive noise cancellation. the paper proposes a real-time application of active noise cancellation in establishing noise-free communication between security personals, firefighters during an emergency fire situation or maintaining law and order in a crowded and noisy location, the paper describes the use of noise cancellation techniques in ensuring social well-being and saving innocent lives and property.
