Abstrakt: Introduction: It has been demonstrated that a listener's temporal-processing capability is predictive of his or her performance on speech recognition, especially in noisy and complex environments. Aims and Objectives: The objective of the study is to check the task-related dependency of gap detection threshold (GDT) and temporal modulation transfer function (TMTF) tests in adults and children. Methods and Materials: The study was conducted on 40 normal-hearing participants, in which 20 children and 20 adults. All the participants in the study were subjected to the basic audiological evaluation. Results: It was observed that there is a significant difference (P < 0.001) between children and adults for GDT and TMTF. In the present study, the relation between GDT and TMTF and their outcome dependency has been measured to show that these two measures correlate in terms of measuring temporal resolution. Conclusions: The results shows that the average value for TMTF (8–9 ms) is comparatively more than GDT (2–3 ms), which indicates that the task involved in GDT is simpler than TMTF.
