Active control of broadband diffuse fields using ∞ - norm pressure minimization

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

This paper presents the performance of active control of broadband diffuse fields. The technique is ∞ - norm acoustic pressure minimization. The theory and simulations of pressure minimization over space and frequency using two-channel and three-channel systems are presented. The work presented in this paper is the second part of the study and we focus on diffuse primary fields with two and three secondary sources. The first part of the study concerned with a plane wave primary field only. A constrained minimization of pressure is also introduced in this paper, to control pressure at various spaces and frequencies. The results show that a good attenuation is achieved at the microphone location or desired range over space and frequency using a two-channel system. However, a better performance could be achieved using a three-channel system.
