Brief summary

To verify and compare the performance of young adults, with normal hearing, with and without clinical symptoms of understanding speech in noise difficulty, using sentences as stimulus. Individuals with normal hearing may be impaired in communication situations in which the signal to noise ratio is unfavorable and interfere negatively on the intelligibility of speech.

Interventions

The Portuguese Sentences Lists test to the individuals was applied. With this test was obtained the speech recognition thresholds in noise and the signal to noise ratio to each ear, using earphone TDH-39P. This is a monaural test and consists of sentences that the individuals should repeat. The sentences and noise were presented using a Toshiba Digital Compact Disc Player - 4149 coupled to the audiometer Fonix (FA-12). The noise intensity was fixed at 65 dB HL. The application was made in a sin
