This paper presents a computational acoustic analysis of the 10:5:4 modular ratio derived from architectural specifications in the Book of Ezekiel (Chapters 40-48). By subjecting these dimensions to finite element method (FEM) and ray-tracing simulation, this study identifies a statistically significant local maximum (3.2\sigma performance gap) in acoustic quality factors. The findings suggest the presence of intentional geometric optimization in the specifications, challenging the consensus regarding the technical capabilities of the era. The results are presented as an empirical contribution to the study of ancient engineering and acoustic design.
