Research Summary: This research project aimed to uncover new neurophysiological indicators that can illuminate the breakdown in neural processes across the speech communication-processing chain. The goal was to enhance our understanding of why speech-in-noise recognition is often compromised under such conditions and create an application that can assist rehabilitation or training of speech-in-noise recognition. The project is structured around three primary objectives: firstly, to delineate the neural underpinnings involved in advanced auditory processing tasks such as auditory encoding beyond threshold levels, auditory object formation, selective attention, and the ability to discern speech from background noise; secondly, to pinpoint both subcortical and cortical metrics that can reliably forecast an individual's capacity to process and understand speech amidst noise; and thirdly, to develop comprehensive clinical assessment tools designed to pinpoint the exact causes of diminished speech-in-noise perception.
