Measured acoustic conditions in the common spaces of two educational buildings at the University of Nebraska–Omaha

Abstract

This paper presents results from an acoustical case study of the atria, corridors, stairways, and other common spaces within two buildings located on the campus of the University of Nebraska-Omaha: the Peter Kiewit Institute and the Barbara Weitz Community Engagement Center. Both buildings, while educational in nature, differ drastically in acoustical design. Impulse responses, noise levels, and transmission loss in both facilities are measured and the resulting acoustic metrics are compared to recommended values for the respective spaces. Descriptions of each building’s architectural features are presented and linked to the measurement results. In particular, many spaces in the Peter Kiewit Institute were designed to expose the building systems, and the lack of acoustical products such as acoustical ceiling tile results in higher noise levels than normally expected. The Weitz Center, however, was designed with great emphasis placed on achieving optimal indoor environmental conditions. The results of this...
