Housing Affordability Impacting Factors In U.S. Urban Areas From 2010 To 2020: An Empirical Review Of Theoretical Factors, Colby Lee Woodson

Community and Regional Planning Program: Theses

This study examines housing affordability in United States Combined Statistical Areas (CSAs) and counties from 2010 to 2020, using American Community Survey and Building Permits Survey data. It evaluates theoretical frameworks from George Galster and Kwan Ok Lee. Using a multiscalar approach, affordability is assessed through a costs-over-income ratio, incorporating both supply- and demand-side factors. A novel contribution is the integration of elder dependency rates, which limit housing turnover and exacerbate supply constraints. Findings indicate that rising full homeownership—particularly among older households—has reduced tenure mobility. The study also shows that CSAs offer a stronger analytical resolution than counties.

Spatial Hearing In Simulated Reverberant Classroom Environments, Gabriel Seth Evan Weeldreyer

Durham School of Architectural Engineering and Construction: Dissertations, Theses, and Student Research

Spatial hearing provides access to auditory spatial cues that promote speech perception in noisy listening situations. However, reverberation degrades auditory spatial cues and limits listeners’ ability to utilize these cues for segregating target speech from competing babble. Hence, spatial unmasking—an intelligibility benefit from a spatial separation between a target and masker—is reduced in reverberant environments as compared to free field. This work tests the hypothesis that interaural decorrelation, the result of increasing reverberation, will broaden the perceived auditory source width with a cascading effect of reduced auditory spatial acuity and subsequently poorer spatial unmasking. To understand the perceptual consequences of …
