Trial Outcomes & Findings for Evaluation of Hearing Aid Benefit (NCT NCT05198713)

NCT ID: NCT05198713

Last Updated: 2023-06-06

Results Overview

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.

PRIMARY outcome

Timeframe: Day 1 and Day 15

Population: It was discovered after data collection that the equipment used in this outcome measure was not functioning properly and the dB level presented was not the dB level that was indicated on the equipment. Therefore, this data was not used and no statistical analysis was done.

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.

92.3 percentage of correct responses
Interval 68.0 to 100.0

SECONDARY outcome

Timeframe: Day 1 and Day 15

Population: All study participants who were fit with study devices who underwent speech in noise testing in both unaided and aided conditions.

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.
