Abstract
In the performing arts spaces, the goal of the coupled volume system is to leverage the clarityand reverberation. This type of design and construction brings unique sound reverberance
characteristics to the coupled volume space, both in the physical and perceptual behavior. In
the physical aspects, sounds reverberation decay often manifests as multiple-slopes decay, and
also influences the interaural decorrelation of listeners. In the perceptual aspects, multipleslopes
decay in the coupled volume system may introduce directional reverberance from the
secondary space. To investigate these sound reverberation characteristics, using Bayesian
analysis and interaural decorrelation coefficient analysis, spatial and temporal reverberation
characteristics can be determined. A preliminary listening test based on experimentally
measured binaural impulse responses is conducted to investigate human listening sensitivity
to directional reverberance. The analysis results suggest that the multiple-slope behavior
is frequency independent, and the turning point time of multiple-slope increases when the
receiver distance from the aperture increases. The preliminary listening test results indicate
that the sensitivity of the human perception of directional reveberance is low. This thesis
introduces the physical analysis methods, experimental measurement process, listening test
methods, and analysis results from both the physical and perceptual sides.
