Clinical Trial Summary

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Speech Intelligibility in Quiet.	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.	Day 1 and Day 15
Secondary	Speech Intelligibility in Noise, Expressed as the Signal to Noise Ratio at Which Participant Can Correctly Repeat 50% of the Words	Speech intelligibility on key words for sentences presented in noise. Noise is presented at a fixed level, and the words are presented at adaptive levels, below and above the noise level. A negative number is better, because it indicates the participant can correctly repeat 50% of the words when the words are below the level of noise. This was done at baseline in the unaided condition on Day 1 of the study, and in the aided condition on Day 15.	Day 1 and Day 15
