Evidence: Emerging

Systematic review finds inconsistent EEG evidence for binaural-beat brainwave entrainment

Systematic review · 2023 · Healthy adults across 14 EEG studies

Roughly half of the reviewed EEG studies reported evidence consistent with brainwave entrainment during binaural-beat stimulation and half did not; methodological differences (carrier frequency, beat frequency, exposure time, masking) plausibly explain the split.

Evidence: Emerging

Meta-analysis finds small-to-moderate effects of binaural beats on anxiety, attention, and pain

Meta-analysis · 2019 · Adults across 22 controlled studies

Binaural-beat exposure showed a small-to-moderate pooled effect (g ≈ 0.45) across memory, attention, anxiety, and pain-perception outcomes, with longer exposure and beat presentation before/during tasks appearing more effective.
