Faculty and Staff

David A. Eddins is a certified clinical audiologist and a fellow of the Acoustical Society of America and of the American Institute for Medical and Biological Engineering. His research interests focus on four broad areas. His collaborative work investigating the impacts of aging on hearing, communication, cognition, and balance involves a variety of research methodologies and advance technologies. Trained as a classical psychoacoustician, understanding fundamental aspects of auditory perception and communication function in real-world settings is a major focus. This work extends to the study of voice quality perception. In the area of voice quality, Eddins partners with speech-language pathologists and engineers to investigate the perceptual, acoustic, and physiological bases of the perception of various characteristics of normal and dysphonic voices with a keen interest in the perception and understanding pediatric dysphonia. His research on hearing and balance enhancement and protection uses various technologies such as ear-worn devices, the use of augmented acoustic environments, and quantification of deficit and benefit via ecological momentary assessment. This work branches into investigations of hearing aid technologies, methods for treating hyperacusis and tinnitus, and the effectiveness of hearing protection devices. His research also involves understanding how the central auditory system processes sound and how that processing may change with aging, hearing loss, and comorbid conditions. This collaborative work frequently involves the use of basic and advanced electroacoustic and electrophysiologic methods. Eddins is actively involved in the development of laboratory, clinical, and ambulatory assessment methods. His research is funded by the NIH and several industry partners and is conducted in collaboration with a variety of scientists and clinicians at UCF and institutions around the world.
