简要总结
The present study will investigate the benefit of hearing aids for speech intelligibility (in both quiet and noisy environments) compared to the unaided condition. Participants will include adults with moderate to moderately severe hearing impairment. The participants will complete laboratory-based speech intelligibility assessments with binaural hearing aids and without hearing aids.

结局指标
主要结局
Speech Intelligibility in Quiet.
时间窗: Day 1 and Day 15
Speech intelligibility for monosyllabic words presented in quiet. The words are presented at a fixed level and the percentage of words correctly repeated is calculated. A higher percentage is better. This was done in both unaided and aided conditions.
次要结局
- Speech Intelligibility in Noise, Expressed as the Signal to Noise Ratio at Which Participant Can Correctly Repeat 50% of the Words(Day 1 and Day 15)
