Tonal noise control using harmonic filters

摘要

This paper describes a Harmonic Filtering approahc to the ocntorl of tonal disturbnaces.THe aim of the paper is two-fold,firstly to present the algorihtm,which has bene used successfully for ocntroling aircraft cabin noise,car and truck cabin noise,auto and bus muffler nosie and pwoer transfromer nosie,and secondly to show how the trackign poerformancre of the controler is related to the fundamental frequency of the noise and the elay in the physical system.
