Abstract
An adaptive delay filter (ADF) consisting of one variable delay and gain is developed for narrowband active noise control. The ADF estimates the time delay and the gain difference between the primary and secondary paths at a given frequency. Multiple ADF systems are connected in parallel to control periodic noise with several narrowband components. Theoretical analysis shows that the amount of noise reduction is determined by the delay difference and the sampling rate.
