effectiveness of brainwave synchronization in alpha, beta, and theta bands by binaural beats on visuospatial working memory

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.
