Added High-Frequency Gain in Dichotic Digits Test for High-Frequency Sensorineural Hearing Loss

Overview

Información sobre este estudio

The purpose of this study is to determine if adding high-frequency gain to the Dichotic Digits Test result in changes in test performance (i.e., is there an effect of providing a high-frequency gain boost to the Dichotic Digits Test when administered to individuals with mild to moderate high-frequency sensorineural hearing loss). Additionally, to determine if there is a relationship between the degree of score change (score of Dichotic Digits Test with high-frequency gain minus score of Dichotic Digits Test without added gain) and performance on the Quick Speech-in-Noise (QuickSIN) test.
