Museum Acoustics: Classification and auralization of design approaches

Abstract

Architecture defines various aspects of museum spaces. Despite often being considered secondary importance by some deciders and designers, the acoustic environment significantly shapes the interpretation of exhibitions and human-building interactions. Focusing on enhancing museum acoustics, this study builds upon previous research that developed a methodology for simulating and evaluating museum soundscapes through psychophysical experiments in immersive environments, showing that participants preferred congruent soundscapes over generic noise maskers [J. Acoust. Soc. Am. 154, A257]. Expanding on these previous investigations, our current research involves cataloging and classifying design approaches currently used within museum contexts—architectural elements, acoustic characteristics, spatial distribution, exhibition strategies, multimodal approaches, etc. Subsequently, we present an auralization method for these museum spaces using the ray tracing method developed for collaborative virtual reality systems [J. Acoust. Soc. Am. 143, 1824]. This method is used within the CRAIVE-Lab at Rensselaer Polytechnic Institute to facilitate tangible analysis, enriching our understanding of these solutions to support future design efforts by guiding architects and acousticians to optimize the museum experience. It offers significant insights into current practices, emerging trends, or notable innovations, thereby promoting more experiential design approaches to shaping the acoustic impacts of the museum environment.
