- Additional information
- Factual information about significance: Multiple personal sound zones, generated electroacoustically in shared acoustic spaces, typically are not robust to perturbations. This article: (i) details a novel formulation of the robustness-optimization problem via a modal decomposition that reveals each loudspeaker-domain mode's contribution to the solution; (ii) quantifies, for the first time, the contribution of loudspeaker and zone geometry to robustness; and (iii) derives a solution allowing calculation of the optimal layout of any given number of position-constrained loudspeakers, providing maximally efficient and robust reproduction. This will greatly assist the ease and quality of implementation of sound zones in domestic and public spaces.
