摘要

The article proposes a method for constructing an active cancellation system based on an algorithm with a block adaptation procedure in the frequency domain. The proposed method has a high convergence rate and can be implemented on a general-purpose computer. The results of simulation modeling and experimental study of the efficiency of the proposed active cancellation system on the created setup are presented. It is shown that using this method for constructing an active noise control system, a suppression level up to 20 dB can be achieved on the experimental setup and up to 28 dB in the simulation model. Special attention is paid to the architecture of the experimental setup and software used.
