OBJECTIVE : The main objective was to examine the effect of central maturation on the auditory temporal resolution in a group of school-age children using Gaps-In-Noise test.
METHODS : The study involved 180 children (6-16 years) with normal hearing, average intelligence and language skills, and adequate scholastic achievement. Subjects were divided into four age subgroups. Investigations involved basic audiological evaluation, screening test battery for central auditory processing, and finally Gaps-In-Noise test.
RESULTS : Comparison of the four age subgroups revealed non-significant age effect on the Gaps-In-Noise test. The approximate gap detection threshold of children was comparable to that of adults. Equivalent data were obtained as a function of the ear, gender, list, and retest.
CONCLUSIONS : Central auditory maturation of the temporal resolution and hence the Gaps-In-Noise test has been established by age 5 years. Consequently, assessment of Gaps-In-Noise test in school-age children provided adult-like normative data. The stability of outcomes across different factors highlights the clinical validity of Gaps-In-Noise test in the assessment of temporal resolution deficit and follow-up after remediation.
