Abstract
This research investigated the effect of inter-aural and isochronic sounds on the synchronization of brain waves and anxiety. The semi-experimental research method was pre-test-post-test without a control group. The statistical population was the students with anxiety in the academic year 2021-2022. 30 people were randomly selected in two groups of inter-aural and isochronic sounds (15 people in each group). The research tools were Beck's anxiety questionnaire (1996) and brain wave recording using brain mapping. The first experimental group listened to interaural sounds and the second listened to isochronic sounds in 12 20-minute sessions. The data were analyzed by univariate and multivariate analysis of covariance using SPSS version 24 software. The findings showed that isochronic and interaural sound has a significant effect on the alpha wave at the F4 point (P<0.05), but only interaural sound is effective on the anxiety variable (P<0.05). The results indicate that inter-aural and isochronic sounds are useful interventions for synchronizing brain waves and inter-aural sounds to reduce students' anxiety; therefore, it is suggested to use these sounds in psychological treatment clinics.
