This article provides a broad overview of the recent advances in the field of spatial active noise control techniques to reduce unwanted noise over a certain region of interest. Thanks to overview of the recent advances in the field of spatial active noise control techniques in local active noise control systems extending the size of the quiet zone seems to be a crucial step to developing the next generation of active control systems for a more personalized and quieter audio product. In this review article, the advances over the past decade in the design and development of spatial active noise control techniques to enlarge the controlled sound zone are reviewed. The study has paid specific attention to measures such as convergence rate, stability and robustness of the algorithms, the size of the quiet zone and how it can be enlarged by configuring the loudspeaker and microphone array geometries. Finally, the authors will discuss the current and future challenges that should be overcome to improve the effectiveness of the recently proposed methods to expand the silence zone.
