This study examines the auditory attribute that describes the perceived amount of reverberation, known as “reverberance.” Listening experiments were performed using two signals commonly heard in auditoria: excerpts of orchestral music and western classical singing. Listeners adjusted the decay rate of room impulse responses prior to convolution with these signals, so as to match the reverber- ance of each stimulus to that of a reference stimulus. The analysis examines the hypothesis that reverberance is related to the loudness decay rate of the underlying room impulse response. This hy- pothesis is tested using computational models of time varying or dynamic loudness, from which pa- rameters analogous to conventional reverberation parameters (early decay time and reverberation time) are derived. The results show that listening level significantly affects reverberance, and that the loudness-based parameters outperform related conventional parameters. Results support the pro- posed relationship between reverberance and the computationally predicted loudness decay function of sound in rooms.
