This binaural beat audio is designed to improve comprehension and attention. It may be useful for tasks requiring focus, memory, and cognitive performance.
This download is a replica of the audio used in the research study completed by Kraus and Porubanova in 2015. Their study hypothesized that binaural beats featuring an alpha wave oscillation would improve working memory capacity. A sample of 40 college students were separated into two groups: a control group and an experimental group. The experimental group listened to a 12-minute recording that featured the sound of the sea and a 9.55Hz binaural beat stimulation. The control group received audio with 12 minutes of sea sounds.
The instrument of this study was an Automated Operation Span Task (AOSPAN) that measured working memory capacity. After the baseline measure of the AOSPAN was obtained, participants were randomly assigned to the control and experiment groups. All participants listened to the 12-minute audio before they retook the AOSPAN. Results found that the experimental group showed statistically significant improvements with a medium-sized effect. This suggests that alpha wave synchronization brought about by binaural beats induced relaxation and increased participants’ ability to filter out irrelevant information.
