A parametric investigation of binaural beats for brain entrainment and enhancing sustained attention.

Binaural beats (BBs) have garnered attention as a highly accessible, noninvasive method to enhance cognitive performance, putatively via brain entrainment. However, the few studies that have directly examined the impact of BBs on sustained attention report inconsistent findings, perhaps due to wide variation in methodology. This study experimentally varied BB parameters while testing the effects of BBs on both sustained attention and brain entrainment.
