Reconfigurable Filter Design for Multiband Noise Cancellation

Noise cancellation is a key source required by most hearing devices and audio gadgets. Developing an adaptive noise cancellation algorithm for recognition of signal effectively to improve Signal to Noise Ratio (SNR) rely on adaptive filters. The simulation results comparing the performance parameters such as SNR, Peak Signal to Noise Ratio (PSNR) and Mean Square Error (MSE) of Buzzing noise, Crackling noise and Static noise for the different algorithms has been presented, showing the large cancellation of noise in the proposed methodology. This paper presents finding and implementing appropriate method so that use of variable filter components for different frequencies will not increase the power consumption of Active Noise Cancellation (ANC) device and reduction of disturbing noise without additional power consumption using appropriate filter.
