研究概览
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. 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.

研究组 & 干预措施
Digital noise management, then quiet listening
Participants with hearing loss who are candidates for hearing aids first listen using the device for hearing loss compensation with digital noise management features, followed by the device for hearing loss compensation for listening in quiet environments.

结局指标
主要结局
Oxygenation Using Functional Near Infrared Spectroscopy (fNIRS)
时间窗: 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.
次要结局
- 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)
