Abstract:It is introduced the adaptive active noise control model based on genetic algorithm,introduces the principle of active noise control system,the adaptive control system lies in its control algorithm to adjust the filter coefficients.The main factors must be considered in the muffler system error,the sound delay,sound attenuation,and the formula by adding the phase change.The system combines neural networks to improve the precision and accuracy,can be used to optimize the structure of the neural network weights.Experiment proves that adaptive active noise control system based on neural network algorithm has a good effect,the system is stable.
Keywords:genetic algorithm  neural network  active noise control system
