Overview
Brief Summary
The purpose of the current study is to measure oxygenation in the PFC using fNIRS in a sample of older adults with hearing loss. Participants will be instructed to listen to sentences in noise at a challenging signal-to-noise-ratio, and to repeat the word that they heard and rate how much subjective listening effort was required in order to make out the words. fNIRS will be measured throughout. Participants will complete the task using a hearing aid program intended for listening in quiet, and a hearing aid program with new advanced noise management features.

Eligibility Criteria
Inclusion Criteria
- •Adults (18-99) years
- •Binaural, symmetrical, sensorineural N2 (mild) to N5 (moderate-severe) hearing loss

Outcomes
Primary Outcomes
Oxygenation Using Functional Near Infrared Spectroscopy (fNIRS)
Time Frame: Session 1, 2, 3 and 4; assessed for up to 2 hours
Infrared light scattered from the prefrontal cortex, which is indicative of concentration of oxygenated blood in that region. fNIRS in the prefrontal cortex is intended to index both motivation and listening effort.
Secondary Outcomes
- Subjective Listening Effort Rating(Session 1, 2, 3 and 4; assessed for up to 2 hours)
- Listening Accuracy(Session 1, 2, 3 and 4; assessed for up to 2 hours)
