Abstract

Structural Active Noise Control (ANC) systems are one of few solutions of the ANC problem which allow to obtain a global noise reduction effect. Unfortunately, due to high dimensionality of these multichannel adaptation systems, which use many sensors and actuators, structural ANC systems are systems with high computational power requirements. A promising group of methods allowing to reduce these requirements are partial update LMS algorithms. In this communication, a modification of partial update LMS algorithms with leakage is presented. The computational power savings are discussed
