The Effects Of Simple Coupled Volume Geometry On The Objective And Subjective Results From Nonexponential Decay, David T. Bradley, Lily M. Wang

Durham School of Architectural Engineering and Construction: Faculty Publications

This project focuses on the individual and interactive acoustic effects of three architectural parameters on the double slope profile from a simple coupled volume system created in the computer modeling program ODEON. The three variables studied are the volume ratio between the main and secondary spaces, the absorption ratio between the two spaces, and aperture size. The resulting energy decay profiles are analyzed using T₃₀/T₁₅ Coupling Coefficient ratios and Bayesian analysis. Coupling Coefficient results show general trends in the effects of the three architectural parameters that match previous research results and the predominant interactive effect between …
