Sound Field Synthesis for Line Source Arrays

Project Description

Line Source Arrays are used for large-scale sound reinforcement (e.g. in arenas, stadiums, for open-air concerts) aiming at the synthesis of homogenous sound fields. The deployed loudspeakers are rigged with different tilt angles and/or electronically controlled in order to provide the intended coverage of the audience zones and to avoid radiation towards the ceiling, reflective walls or residential areas. The research objective is to find algorithms that are based on analytic sound field synthesis and that provide improved optimization strategies compared to purely numerical solutions. Subproblems may still be solved numerically if necessary.
