Description
Summary:Purpose: detecting the sensitivity to evaluate the temporal resolution ability, by comparing Randon Gap Detection Test (RGDT) and Gaps- In-Noise (GIN) tests, in addition to suggesting reference values in these tests for elderly people. Methods: 38 elderly people, 24 women and 14 men, aged between 60 and 82 years, with normal hearing or sensorineural to moderate hearing loss; with symmetry between the ears; Type A tympanogram, acoustic reflex, with auditory processing complaints. All patients underwent basic evaluations to characterize the peripheral hearing--RGDT and GIN. Results: the sensitivity found for RGDT regarding the identification of the temporal resolution ability was 88.64% and 67.65% in GIN. The mean values for the gap detection thresholds in GIN test were around 8ms and for the RGDT test in 23,13ms. Conclusion: RGDT test presented greater sensitivity for detecting the change in temporal resolution ability. The values of temporal resolution thresholds suggested as reference values for the elderly people, are 8ms for GIN and 23.13 ms for RGDT.

Metodos: participaram 38 idosos, 24 mulheres e 14 homens, com idades entre 60 e 82 anos, com audicao normal ou perda auditiva neurossensorial ate moderada; com simetria entre as orelhas; timpanograma tipo A, reflexos acusticos presentes, com queixa de processamento auditivo. Todos Foram submetidos a avaliacao basica para caracterizar a audicao periferica, RGDT e GIN. Resultados: a sensibilidade encontrada para o teste RGDT na identificacao da habilidade de resolucao temporal foi de 88,64% e no GIN de 67,65%. Os valores medios para o limiar de deteccao de gap no teste GIN encontraram-se em torno de 8ms e para o teste RGDT em 23,13ms. Conclusao: o teste RGDT demonstrou maior sensibilidade para deteccao da alteracao da habilidade de resolucao temporal. Os valores dos limiares de resolucao temporal, sugeridos como valores de referencia para idosos, sao de 8ms para o GIN e 23,13 ms para o RGDT Descritores: Percepcao Auditiva; Testes Auditivos; Transtornos da Percepcao Auditiva; Audicao; Compreensao
