Auditory processing performance in blind people.

UNLABELLED Hearing has an important role in human development and social adaptation in blind people. OBJECTIVE To evaluate the performance of temporal auditory processing in blind people; to characterize the temporal resolution ability; to characterize the temporal ordinance ability and to compare the performance of the study population in the applied tests. METHODS Fifteen blind adults participated in this study. A cross-sectional study was undertaken; approval was obtained from the Pernambuco Catholic University Ethics Committee, no. 003/2008. RESULTS Temporal auditory processing was excellent--the average composed threshold in the original RGDT version was 4. 98 ms; it was 50 ms for all frequencies in the expanded version. PPS and DPS results ranged from 95% to 100%. There were no quantitative differences in the comparison of tests; but oral reports suggested that the original RGDT original version was more difficult. CONCLUSIONS The study sample performed well in temporal auditory processing; it also performed well in temporal resolution and ordinance abilities.
