Abstract This paper presents a method of ANC for transformer noise control utilizing a speaker and microphone pair. In this study, the main focus is on identifying the dynamic characteristics of speaker - amplifier -microphone path. This study presents a theoretical method to identify the dynamic characteristics of speaker-microphone pairs. The transfer functions of microphone - speaker pair have been estimated utilizing sequential least square(SLS) algorithm. We identified the estimated transfer function has stable pales and zeros in z-plane. This paper also propose an architecture for the noise cancellation to which we applied the estimated transfer function.
