Alertness, Attentiveness, Analytical Problem Solving
Binaural beats at 20 Hz fall within the beta brainwave frequency range (13-29.9 Hz), which is associated with fast neural activity linked to cognitive tasks, alertness, attentiveness, analytical problem solving, decision making, and conscious thinking. Listening to a 20 Hz binaural beat, typically created by presenting a 100 Hz tone to one ear and a 120 Hz tone to the other, is theorized to encourage the brain to synchronize with the 20 Hz frequency difference, potentially promoting states of energy, focus, and concentration. Some individuals report a euphoric feeling, akin to a "jogger's high," when exposed to frequencies around 20 Hz, although the stimulating nature of beta frequencies means they should be used cautiously to avoid over-arousal. Research has explored the effects of 20 Hz binaural beats, with one study finding that a 20 Hz binaural beat condition led to improved performance on a cognitive task compared to a control condition.
