MARCULINO, Carolina Finetti; RABELO, Camila Maia and SCHOCHAT, Eliane. Gaps-in-Noise test: gap detection thresholds in 9-year-old normal-hearing children. J. Soc. Bras. Fonoaudiol. [online]. 2011, vol.23, n.4, pp. 364-367. ISSN 2179-6491. http://dx.doi.org/10.1590/S2179-64912011000400012.
PURPOSE: To establish the standard criteria for the Gaps-in-Noise (GIN) test in 9-year-old normal-hearing children; to obtain the mean gap detection thresholds; and to verify the influence of the variables gender and ear on the gap detection thresholds. METHODS: Forty normal-hearing individuals, 20 male and 20 female, with ages ranging from 9 years to 9 years and 11 months, were evaluated. The procedures performed were: anamnesis, audiological evaluation, acoustic immittance measures (tympanometry and acoustic reflex), Dichotic Digits Test, and GIN test. The results obtained were statistically analyzed. RESULTS: The results revealed similar performance of right and left ears in the population studied. There was also no difference regarding the variable gender. In the subjects evaluated, the mean gap detection thresholds were 4.4 ms for the right ear, and 4.2 ms for the left ear. CONCLUSION: The values obtained for right and left ear, as well as their standard deviations, can be used as standard criteria for 9-year-old children, regardless of ear or gender.
