Background and Aim: Auditory temporal resolution skill is calculated according to the minimum required time to analyze or integrate acoustic events. This skill, which is essential for speech perception, was evaluated by gap detection tests. The aim of this study was to determine the presence or absence of any differences between the right and left ear in the gap detection test.
Methods: After performing auditory tests to rule out any hearing loss or auditory processing disorders, the gap detection test was administered to 40 adults.
Results: Gap detection thresholds were 5.35 ms and 5.30 ms in the right and left ear, respectively, and the average correct answers percentages were 69.03% and 68.03% in the right and left ear, respectively. According to these data, results were similar for both ears.
Conclusion: There is no laterality in temporal resolution tasks. However, we cannot generalize the results of the present study as being applicable to the whole society.
