Acoustically Sensitive Large Assembly Spaces at School: An Elementary School Retrofit and Expansion

Abstract

This thesis argues for prioritizing the acoustic dimension of design and embracing an attitude of “acoustic delight” rather than “do no harm.” The thesis investigates three approaches to shaping the acoustic experience of large assembly spaces in schools: fixed acoustics, variable acoustics, and acoustic microclimates. The acoustic retrofit and expansion of a typical double-duty gymnasium/cafeteria is studied, motivated by improving the health and wellness of students and staff. Design options are evaluated using acoustic simulations with quantitative metrics for reverberation time, speech intelligibility, overall sound levels, and quieter areas within the large assembly space. The study explores preliminary acoustic design methods and tools to add to the architect’s toolkit. Architects can design creatively with qualities of sound, just as they do with qualities of light. It is time for architects to engage the full variety of sensory experiences that support a child’s social and emotional development. Six supplementary sound recordings are included as MPEG/WAV files. They illustrate acoustic experiences at three large assembly spaces and commons areas: the existing study site, a site with sub-optimal acoustic experience, and a newer school designed with high priority on acoustics.
