Abstract
For decades numerical simulations of room acoustic phenomena have been developed and are now rather prolific in the Architectural Acoustics community. These tools are often used by consulting firms for predicting acoustic properties of new constructions. Some research projects have used these numerical simulations to recreate historical buildings in virtual reality presentations. These virtual reconstructions are mostly used for project publicity or public presentations. They are rarely used as part of scientific study by historians. The goal of this project is to examine the use of virtual acoustic architectural reconstructions as a scientific tool. Methods for creating calibrated models, implementing multidisciplinary requirements, and use evaluations are part of this study. The goal is to provide a sort of “acoustic viewfinder” towards the past. As a test case, this work will consider performance spaces, such as theatres, and their evolution in design over the past century.
Context
By combining measurement and modeling techniques with expertise in virtual reality, we are able to create interactive environments, immersive scenes representing historical venues. This project follows recent initiatives to use modern technology to explore the history, “acoustic archeology”, recreating architecture that no longer exists to better understand it and its context. Previous work studied the room in which the science of room acoustics originated in the early twentieth century (see Katz &Wetherill). Related projects have recreated and examined ancient Greek theaters.

Objectives
Working in collaboration with Historians and Architects, the objective of the project is to examine various methods for creating and auralizing historical architectures for study by researchers in various disciplines. After a survey of various existing modeling and rendering methods and preliminary evaluations, the first goal will be to define a set of specifications for the creation of calibrated acoustic models. The second phase will be the construction of a series of test cases following historical records, resulting in an interactive audio-visual rendering. The third objective will be to evaluate the suitability of the results with the associated historians and to revise the specifications as needed. The final objective will be the creation of a showcase model incorporating several key historical elements. This model will be the subject of study with a panel of naïve historians specifically interested in the acoustical performance of architectural constructions.
Work program
Phase 1, SPECIFICATION, is expected to take ~6 months, including mastering the architectural acoustic simulation software and running basic test cases.
Phase 2, 1ST GENERATION MODEL, is carried out over the next 6 months, includes discussions with historians, selection of several test case sites, documentary investigations, and on-site visits to selected buildings.
Phase 3, 1ST EVALUATION, of the test case models is expected to be carried out over 4-6 months. This includes development of the necessary experimental protocol to evaluate the benefit of auralization for historians.
Phase 4, 2ND GENERATION MODEL, incorporates the results of the previous study producing a showcase model for testing with historians and other researchers (3-4 months).
The study concludes with a final evaluation (2ND EVALUATION) of the resulting model over the course of 4-6 months.
The remaining time is devoted to analysis and publication of results as well as time allocated to writing the thesis manuscrip
