%X A resolu  o temporal permite identifica  o de pequenas diferen as ac¨²sticas nos aspectos segmentais da fala e pode ser avaliada por meio do Random Gap Detection Test (RGDT) e Gaps-In-Noise Test (GIN), os quais possuem diferentes parametros ac¨²sticos. OBJETIVO: Comparar o desempenho de escolares sem dificuldades de aprendizagem e/ou queixas auditivas, na aplica  o do GIN e RGDT, e analisar diferen as de desempenho entre os procedimentos. M¨¦TODO: Estudo de coorte contemporanea com corte transversal. Avaliaram-se 28 crian as, de 8 a 10 anos, as quais foram submetidas ao RGDT e GIN ap¨®s avalia  o audiol¨®gica perif¨¦rica pr¨¦via. RESULTADOS: N o foram encontradas diferen as estat¨ªsticas em rela  o ao g¨ºnero e faixa et¨¢ria, frequ¨ºncias no RGDT e orelhas no GIN. A m¨¦dia do limiar de detec  o de gap do RGDT foi de 9,25 ms ¡À 3,67, e no GIN foi de 4,32 ms ¡À 0,61 (orelha direita) e 4,43 ms ¡À 0,79 (orelha esquerda). Os resultados do GIN foram estatisticamente menores do que no RGDT (p < 0,001). CONCLUS O: Ambos os testes demonstraram resolu  o temporal normal nas 28 crian as. O GIN apresenta vantagens em rela  o ¨¤ facilidade de aplica  o, natureza da tarefa solicitada, est¨ªmulo empregado e forma de apresenta  o. Por¨¦m, o RGDT apresenta vantagens no tempo necess¨¢rio para a aplica  o e registro de pontua  o Temporal resolution enables the identification of fine differences in speech segmental aspects. Random Gap Detection Test (RGDT) and Gaps-In-Noise Test (GIN) evaluate such skills, by using different acoustic parameters. OBJECTIVE: To compare the performance of normal school aged children without learning disabilities and/or hearing complaints in the GIN and RGDT, and analyze potential performance differences in these two procedures. METHOD: Cross sectional contemporary cohort study. 28 children, aged 8-10 years were evaluated. After peripheral audiological evaluation, RGDT and GIN were performed. RESULTS: There were no statistical differences in performance between gender and age on the RGDT and GIN tests, between the right and left ears on the GIN test, and between frequencies on the RGDT test. The mean detection threshold gap for RGDT was 9.25 ¡À 3.67 ms, and for GIN was 4.32 ¡À 0.61 ms (right ear) and 4.43 ¡À 0.79 ms (left ear). The results of the GIN Test were statistically lower than those from the RGDT (p < 0.001). CONCLUSION: Both tests indicated normal temporal resolution for all 28 children. GIN test presents advantages regarding the ease of application, task variable, stimuli and presentations form. However, the RGDT has advantages concerning the time require
