Background and Objective: This study aimed to determine the effect of synchronization of brain waves in alpha, beta, and theta bands by the Binaural beats on visuospatial working memory. 
Materials and Methods: The present quasi-experimental study was conducted based on a pretest-posttest control group design. In this regard, 60 students were selected by the available sampling method and randomly divided into three experimental groups and one control group (n=15 each). All subjects were assessed in the pre-test and post-test stages by the Corsi blocks tapping test. Participants in the experimental groups received 15, 9, 5, and 6 Hz binaural beats for 12 min. The collected data were analyzed using a one-way analysis of covariance.
Results: The findings showed that 15 Hz binaural beats (beta bands) significantly improved the subject's visuospatial working memory (P<0.05).
Conclusions: Given that working memory is the basis of numerous cognitive functions, using 15 Hz binaural beats could improve the visuospatial working memory in these people
