Abstract
How the brain hears, responds to adversity, and adapts with hearing interventions, can inform clinical decisions, device design and, ultimately, broader policy and practice. While audiological practice today remains focused on the use of a limited test battery, improving assessment techniques to identify how well adults comprehend speech in across a range of listening environments (and beyond the pure tone audiogram) can lead to greater personalization of treatments, devices, and rehabilitation. Moreover, understanding how the brain responds to interventions, such as cochlear implants or rehabilitation programs for tinnitus, could improve our understanding of which work, and for whom. In this presentation, I discuss a number of experimental techniques that we have used to explore how the brain responds to sound under challenging listening conditions using speech-in-noise and vocoded stimuli. In addition, I will discuss how the brain adapts after cochlear implantation for those with significant hearing loss, and following a 30-week rehabilitation program for those with significant tinnitus. Finally, potential limitations of electrophysiological measures within current clinical assessment batteries will be considered, as well as opportunities to better understand how we can improve hearing healthcare for individuals and populations.
