Effects Of Reverberation Conditions And Physical Versus Virtual Source Placement On Localization In Virtual Sound Environments, Anna Catton
Durham School of Architectural Engineering and Construction: Dissertations, Thesis, and Student Research
Sound field synthesis systems vary in number and arrangement of loudspeakers and methods used to generate virtual sound environments to study human hearing perception. While previous work has evaluated the accuracy with which these systems physically reproduce room acoustic conditions, less is known on assessing subjective perception of those conditions, such as how well such systems preserve source localization. This work quantifies the accuracy and precision of perceived localization from a multi-channel sound field synthesis system at Boys Town National Research Hospital, which used 24 physical loudspeakers and vector-based amplitude panning to generate sound fields. Short bursts of broadband speech-shaped …
