Temporal Resolution: performance of school-aged children in the GIN - Gaps-in-noise test

Time resolution hearing skill is the minimum time necessary to solve acoustic events, which is fundamental for speech understanding, and which may be assessed by gap-detection tests, such as the Gaps-in-noise test (GIN).Aimthe purpose of this study was to verify the performance of time processing ability in children with no hearing and/or education difficulties by applying the GIN test in both genders and ages from 8 to 10 years.Study designa prospective cross-sectional contemporary cohort.Material and methodThe GIN test was applied to 75 school-aged children separated into three groups by age.ResultsThe findings showed no statistical differences among age groups or ears. Males had slightly better responses than females on the percentage of correct responses only.ConclusionThe gap threshold and percentage of correct responses were calculated regardless of the ear, gender or age, and were respectively 4.7ms and 73.6%. Based on a 95% confidence interval, the cut-off criterion for normal and abnormal performance was 6.1ms for the mean gap detection threshold and 60% for the percentage of correct responses.
