In the present paper, several algorithms are analyzed and implemented for active noise cancellation To test their performance we used multiple sound patterns which we simulate separately to specify the best algorithm performance for each sound. In order to analyze and control all parameters from each algorithm, Simulink™ basic blocks (delays, algebraic operators) were used for simulation development. Simulations results show how some algorithms are better than other depends on the noise to cancel in the system.
