Abstract
The paper presents experimental results and theoretical investigations of non-stationarity problem in creation of 3-D zones of quiet using active noise control (ANC). The non-stationarity follows from necessity of a change of the error microphone location. Laboratory environment and experiment configuration is presented. The basic ANC algorithm used is feed-forward compensation with finite impulse response filtration. Parameters of the filter are adapted on-line with FX-LMS algorithm. Experimental results show dependence between step factor of FX-LMS and quality of the noise cancellation. The dependence is explained in the paper. The results presented also show a necessity of a future investigation prospected in the paper.
