Abstract

St Cecilia’s Hall, Scotland’s oldest purpose-built concert hall, has a distinctive elliptical-domed shape which exhibits non-diffuse acoustical characteristics. This talk presents preliminary results from a study which utilities a state-of-theart wave-based, finite-difference time-domain (FDTD) simulation platform to investigate the acoustics of St Cecilia’s Hall. The outputs of the wave-based simulation are compared to measurements in the space, and to a commercial geometrical acoustics (GA) software that relies on diffuse-field assumptions.
