Plain-language 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.
