Abstract

A larger number of research studies has been performed with different people and objectives and have shown that the sentence recognition test in noise is the best instrument to evaluate individuals' daily communication. However, we believe these tests are not applied so frequently because they require a lot of research to establish the parameters and variables related to their application and interpretation of the results. To check the reliability of the recognition threshold of the sentences in quiet and in noise for a group of young normal listeners. Transversal cohort. The group comprised 40 subjects, 20 males and 20 females, with ages between 18 and 28 and all of them with normal hearing threshold. First, we applied the Basic Audiological Evaluation and after this, the Sentence Recognition Threshold test in quiet (LRSS) and in noise (LRSR). The sentences and the noise (fixed in 65 dB HL) were presented monoaurally, by earphones through "ascending-descending" strategy. The test and retest were done in different evaluation sessions, with an interval of seven days between them, respecting the same hour of evaluation. The results showed strong positive statistically significant correlation between the test and retest of LRSS, b...Continue Reading
