Clinical Trial 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 indicate what they heard using a closed-set response interface. Participants will complete 4 sessions: a training session, and a session for each condition. During each test session, participants will be instructed to listen to at least 100 sentences. Oxygenation, response times, and listening accuracy will be measured throughout.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Oxygenation using functional near infrared spectroscopy (fNIRS)	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.	Up to 1 hour during 1 session (per condition - for a total of 3 hours)
Primary	Response times	Response times will be defined as the amount of time between the beginning of a stimulus and when participants submit their responses.	Up to 1 hour during 1 session (per condition - for a total of 3 hours)
Primary	Listening accuracy	Speech understanding in noise percent correct scores	Up to 1 hour during 1 session (per condition - for a total of 3 hours)
