Analysis and control of multi-zone sound field reproduction using modal-domain approach

Zhang, Wen; Abhayapala, Thushara; Betlehem, Terence; Fazi, Filippo M.

Description

Multi-zone sound control aims to reproduce multiple sound fields independently and simultaneously over different spatial regions within the same space. This paper investigates the multi-zone sound control problem formulated in the modal domain using the Lagrange cost function and provides a modal-domain analysis of the problem. The Lagrange cost function is formulated to represent a quadratic objective of reproducing a desired sound field within the bright zone and with constraints on sound...[Show more]
