Primary Outcome Measures
NameTimeMethod
Speech Intelligibility in NoiseDay 1 of a one day study

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.
