简要总结
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.

结局指标
主要结局
Speech-in-noise performance
时间窗: Up to 2 hours during 1 session
Number of words repeatedly correctly for a given listening condition.
Listening effort
时间窗: Up to 2 hours during 1 session
Listening effort inferred from infrared light scattered from the prefrontal cortex, which is indicative of concentration of oxygenated blood in that region. A higher concentration is indicative of more listening effort.
