SA-4: Shining a light on listening effort: using infrared neuroimaging to reveal brain benefits of hearing aids

Speaker

Listening effort is an important outcome for understanding the benefits of hearing aids and their features, particularly in noisy listening conditions. However, there is limited consensus from the research / clinical community on the most effective ways to measure listening effort. In this presentation, we will explore a relatively new neuroimaging technique called functional near-infrared spectroscopy (fNIRS) and assess its ability to measure areas in the brain associated with listening effort. We will review a series of studies showing fNIRS’ ability to measure cortical benefits of amplification and AI-based noise management. We will also discuss technical details behind fNIRS and how to consider our research findings in hearing contexts.

Learning Objectives:

  1. Identify areas of the brain associated with listening effort.
  2. Define functional near-infrared spectroscopy (fNIRS) and describe contexts in which it is sensitive to hearing aid use.
  3. Interpret how research on listening effort using fNIRS might inform counseling on hearing aid benefits in practice.
