摘　　要：本文采用自适应有源噪声控制技术(AANC)解决非晶变压器的噪声问题。考虑非晶变压器噪声的特点,误差通道具有的不确定性,采用在线辨识误差通道的方法以达到完全自适应消声。In order to cancell the noise of Not-crystal Transformer,The paper uses the adaptive active noise control（AANC）.In view of the off-line identification error channel＇s shortcoming,considered the characteristic of the Not-crystal Transformer noise that the error channel has the uncertainty,therefore the online identification error channel is used to denoise.The simulation results show that this system has the good denoising effect.
