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. Adults with hearing loss will be asked to repeat the final word from low-context sentences in noise at two SNRs; a hard SNR (individually-measured SNR-50), and an easy SNR (SNR-50 + 10 dB) both without and with hearing aids set to a directional mode. The procedure will be a within-subject repeated measures. Stimuli will be randomized.

Conditions

Interventions

DEVICE

Hearing aids

Participants will listen to stimuli in the environment while wearing hearing aids which should make the stimuli more audible. Speech in noise performance is expected to improve and PFC oxygenation is expected to be reduced in this condition.

OTHER

Unaided

Participants will listen to stimuli in the environment with their hearing loss. Speech in noise performance is expected to decline and PFC oxygenation is expected to be increased in this condition.
