| Abstract: | An active noise control system is developed, and an experimental study on the control of low frequency noise inside central air conditioning ventilation duct is carried out by means of adaptive active noise control method. The main effect factors on attenuation of the active noise control system are analysed, and the ways to further raise the attenuation are discussed. |
