The aim of this work is to study the sound field distribution in an experimental scale-model of two coupled rooms. An automatic scanning mechanism moves a microphone in small grid steps to measure room impulse responses at each grid point. The measurements cover the entire two-dimensional area of the coupled rooms. Sound energy distributions can be analyzed in the form of animated visual displays, revealing sound propagation across the coupling aperture and inside each room. This paper…

TLDR
This study makes use of Hagia Sophia's rich formal and material characteristics to conduct a comprehensive investigation of room acoustics coupling and finds the source-receiver distance and positioning within different sub-spaces appear to be the underlying determinant of multi-slope sound decay pattern.

Sampling the sound field in auditoria using large natural-scale array measurements.
TLDR
The experimental data allow wave field animations demonstrating how sound propagating at grazing incidence over theater seating is scattered from rows of chairs (seat-dip effect) and visualized data of reflections and scattering from an auditorium's boundaries give insights and opportunities for advanced analyses.
Sound energy decay in coupled spaces using a parametric analytical solution of a diffusion equation.
TLDR
A heuristic model of sound energy behavior based on an analytical solution of the commonly used diffusion equation and physically justified approximations is proposed and validated by means of comparisons to scale model measurements and numerical geometrical acoustics simulations, both applied to the same simple concert hall geometry.
Adapting a randomized beam-axis-tracing algorithm to modeling of coupled rooms via late-part ray tracing
The ability of computational geometrical acoustics to accurately model energy decay in systems of coupled rooms is investigated both theoretically and experimentally. Unlike single-volume rooms,…
Visualizations of sound energy across coupled rooms using a diffusion equation model.
TLDR
This study reveals a "reversal" characteristic of energy flow directions which seems to be dependent on the size and location of the aperture, and animations of time-dependent energy flow direction visualize the energy flows across coupled spaces.
A hybrid modal analysis for enclosed sound fields.
A hybrid modal expansion that combines the free field Green's function and a modal expansion will be presented in this paper based on a review and an extension of the existing modal analysis theories…
Optimum absorption and aperture parameters for realistic coupled volume spaces determined from computational analysis and subjective testing results.
TLDR
This project utilizes computational modeling to study the effects of varying two architectural parameters, absorption ratio and aperture size, in a realistic coupled volume concert hall, and subjective testing shows that, in general, listener preference is inversely proportional to the level of double slope effect.
