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

Durham School of Architectural Engineering and Construction: Dissertations, Thesis, 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 …

In This Time And Place, Christy Aggens

School of Art, Art History, and Design: Theses and Student Creative Work

I seek out and spend time in relatively wild outdoor locations and create art based on my observations. The resulting work explores time and place, while the creation of the work increases my engagement with the environment. This process serves as a reminder that time is relative and life itself is continuous.

I start by finding time in locations where nature has been given a chance to thrive and where the sound of human activity is at a minimum. During these retreats, I use my senses to absorb information and document the experience by journaling, making recordings, taking photographs, drawing, …
