Abstract
Schroeder’s integration method broke the new ground in classical architectural acoustics. Schroeder’s integration method yields sound energy decay functions from room impulse responses. For reverberation time estimation based on a parametric model, a nonlinear regression method has been proposed. The nonlinear regression method yields reverberation time estimates, insensitive to background noise and the upper limit of integration. Recent interest in acoustically coupled-volume systems has prompted new challenges in analyzing sound energy decay characteristics, which are more complicated than just single-rate decays. This chapter will demonstrate a suitable framework for this room-acoustics application using Bayesian inference and the Schroeder’s integration as the foundation of the advanced model-based energy decay analysis. Based on the Schroeder’s integration, two levels of inference, decay order selection and decay parameter estimation, are discussed in details.
