A influência das perdas auditivas sensorioneurais na ordenação temporal

PURPOSE: to evaluate the temporal ordering ability in adults with mild to moderate sensoryneural hearing loss, through the Duration Pattern Test, in order to determine whether these losses affect the performance of the aforesaid test. METHOD: 57 adults from 20 to 59 years of age were evaluated, being 30 male and 27 female. All of them underwent a screening test consisting of medical history, ENT examination, basic audiological testing and hearing process screening with the Dichotic Digit Test. After this process, the participants were allocated into three groups, namely: G1 (normal hearing for the averages of 0.5 / 1 / 2 and 3/4/6 KHz), G2 (mild hearing loss in at least one of the averages) and G3 (moderate loss in at least one of the averages). The results were analyzed through comparison between normal hearing and the presence of hearing loss (G2 + G3) and among the three groups described. The normality index used was 70% of successes. For statistical analysis, the tests used were Nonparametric Mann-Whitney, Kruskal-Wallis ANOVA, "One-way" Analysis of Variance, student's t and chi-square. The determining criterion of significance adopted was level 5%. RESULTS: there was a significant presence of men with hearing loss in the group. The percentage of correct answers in the overall sample was 62.3%, revealing no statistically significant difference among groups. CONCLUSION: the temporal ordering ability evaluated by the Duration Pattern Test is not influenced by mild to moderate sensoryneural hearing loss.
