High-Frequency Threshold (10 - 20 KHz) in Top Grade Ranking Primary School Children

I- The thresholds were not significantly different at any frequency (P>0.05) in test re-test trials.2- The test minus re-test threshold for individual ears showed clinically reliable and acceptable range 0-10dB SPL for at least99.74% of the ears at all frequencies.3- The threshold differences between right & left cars in two test sessions were not significantly different (P>0.05) except for 14KHz.4- High- frequency threshold in two test sessions showed no significant difference between girls & boys at all frequencies (P>0.05) (except for 16 & 20 KHz in right ear and 10 KHz in left ear). This test can be used for evaluation of individual high-frequency threshold in all frequency as test re-tests tria1. Moreover, this test may use as a beneficial tool for monitoring different endogenous and exogenous auditory pathologies.Consideration: it is found that this research is valid only among situation of this project. Any generalization needs further research.
