Effects Of Hearing Aid Amplification On Robust Neural Coding Of Speech, Jonathan Daniel Boley
Effects Of Hearing Aid Amplification On Robust Neural Coding Of Speech, Jonathan Daniel Boley
Open Access Dissertations
Hearing aids are able to restore some hearing abilities for people with auditory impairments, but background noise remains a significant problem. Unfortunately, we know very little about how speech is encoded in the auditory system, particularly in impaired systems with prosthetic amplifiers. There is growing evidence that relative timing in the neural signals (known as spatiotemporal coding) is important for speech perception, but there is little research that relates spatiotemporal coding and hearing aid amplification.
This research uses a combination of computational modeling and physiological experiments to characterize how hearing aids affect vowel coding in noise at the level of …
Developing A Drug Delivery System For Treatment Of Vocal Fold Scarring, Aaron Michael Kosinski
Developing A Drug Delivery System For Treatment Of Vocal Fold Scarring, Aaron Michael Kosinski
Open Access Dissertations
Vocal fold scarring is an affliction that results in the formation of a disorganized and stiff extracellular matrix (ECM) with abnormal ECM component densities & structures including a significant increase in collagen deposition. It is caused by improper healing post injury and results in profound changes in the biomechanical properties of the vocal folds impairing their ability to generate a normal mucosal wave during phonation.
Finding an effective treatment for vocal fold scarring has been elusive. Currently, treatments seek temporary solutions that correct glottal incompetence and reduce stiffness caused by the scar through the augmentation of the vocal folds using …
