Abstract:
Binaural beat (BB), as a non-invasive auditory beat stimulation type, has found its potential applications in cognitive domains. This review presents a proper summary to deepen our understanding of the soundness of the BB technique by looking into its applications, possible mechanisms of action, effectiveness, limitations, and potential side effects. BB has been claimed to improve cognitive and psychological functions such as memory, attention, stress, anxiety, motivation, and confidence. We have also looked into preclinical and clinical research studies that have been performed using BB and proposed changes in the brain following the application of BB stimulations, including EEG changes. This review also presents applications outside the cognitive domain and evaluates BB as a possible treatment method.

Plain Language Summary
Auditory beat stimulation is a popular method to improve mood and cognition. It has two types of monaural beats and binaural beats. In this study, we review preclinical and clinical studies that have used binaural beats to present mechanisms of action, effectiveness, limitations, and potential side effects of this type of auditory beat stimulation. Based on the results, it can be said that it is a useful method for rehabilitation training. However, further research is needed to assess the role of personality traits and factors such as duration, frequency, and carrier tones of the stimulation.
