Trial Outcomes & Findings for Benefits of Assistive Listening Device for Speech Intelligibility (NCT NCT05072470)
NCT ID: NCT05072470
Last Updated: 2023-02-13
Results Overview
The percent of correctly repeated words, when a list of 10 sentences is presented in noise. Ten sentences are presented at a certain loudness level while background noise is presented simultaneously at a specific loudness level. The number of words repeated correctly is calculated from the total number of words presented.
