Evidence in one paragraph
The existence of the binaural-beat percept is not controversial. The claim that it reliably entrains brain oscillations or improves cognition is more uncertain. The 2023 PLOS ONE systematic review found inconsistent EEG results, while a 2023 meta-analysis of attention and memory outcomes found an overall positive effect but conflicting findings in specific conditions.
