My programmatic line of research is motivated by the fact that many people with hearing loss do not seek out or find benefit from audiologic interventions. My research grows directly out of my experience as a clinician and aims to solve problems my patients commonly face in their daily lives. Ultimately, I aim to grow the number of listeners with hearing loss who utilize audiologic interventions and improve the benefit they experience when they do. Some of the big questions I aim to answer are:
- What drives variance in hearing aid and other audiologic intervention outcomes?
- Why do so many people who are hearing aid candidates not use hearing aids or report little benefit from hearing aids and how can this be improved?
- Why are many hearing aid technologies that show efficacy in traditional laboratory experiments largely ineffective in the real world, especially in complex listening environments?
- How can signal processing be improved to provide more benefit in real-world complex listening environments?
- How can we improve hearing aid and other audiologic intervention outcomes in daily life for populations with complex communication needs and circumstances, such as adults with dementia and children with neurodevelopmental and other disabilities?
- How do the environments, listening activities, lifestyles, and demographics of hearing aid users affect intervention outcomes? How are intervention outcomes controlled by the interactions of these factors?
My approach to these questions is rooted in the theory of auditory ecology—the interactions between the types of real-world soundscapes listeners encounter and their individual perceptual demands in those environments. My work begins from the idea that listening always occurs in a context with many interacting factors. These factors are typically not well-represented by traditional research in audiology and hearing science. To better understand the complex relationships between soundscapes, listeners, and interventions in the real world, I broadly employ two novel methods. In the first, I bring ecological validity to traditional psychoacoustic and hearing aid efficacy experiments. In the second, I study listeners in the real-world environments as they go about their daily lives. My commitment to ecological validity and focus on real-world applications of research findings primarily forms my identity as a researcher.
