Effect of Pitch of Sound on Auditory Reaction Time : A Gender Based Study.

ABSTRACT

Reaction time has physiological significance and is a simple and non – invasive test for peripheral as well as central neural structures. And the reaction time is influenced by different factors. The purpose of this study was to find out whether the reaction time was faster for high pitch auditory or low pitch auditory stimulus. In this study auditory reaction time (ART) was studied in 125 male & 125 female medical students in the age group of 17-20 years. Subjects were presented with two auditory stimuli i.e. High & Low pitch sound stimuli. Paired and unpaired ‘t’ test was used at appropriate places as a statistical test. The p value <0.05 was considered significant. The reaction time to low pitch sound stimuli was significantly lower than to high pitch sound stimuli in both sexes. Auditory reaction time in females was significantly higher compared to males
