简要总结
Speech intelligibility in noise will be evaluated in adults with moderate to moderate-severe sensorineural hearing loss using a Phonak Roger microphone and hearing aid with compatible Phonak Roger receiver. Target speech will be presented from multiple directions while competing diffuse background noise is presented simultaneously. Participants will repeat back words and percent correct is calculated.

结局指标
主要结局
Lateralization Hearing Ability
时间窗: Day 1 of 1 day study
Participants indicate which direction (left, center, or right) target speech sentences are coming from while competing noise is also presented via four corner speakers. A higher number of correct responses indicates better lateralization ability. This will be done with two Roger microphone systems (Roger On and Roger Select)
Spatial Hearing Ability
时间窗: Day 1 of 1 day study
Participants repeat sentences presented from the left speaker, while ignoring overlapping competing sentences presented from the right speaker. A higher percentage of correctly repeated words indicates a better spatial hearing score. This task will be performed using two Roger microphone systems (Roger On and Roger Select)
