Headline finding
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.
Limitations
- High heterogeneity between studies: protocols, beat frequencies, carrier tones, and outcomes varied widely.
- Blinding is difficult — participants can often tell they are hearing a pulsing tone, so expectation effects are hard to exclude.
- Small individual studies dominate the pool; publication bias cannot be ruled out.
Why this evidence label
A pooled positive effect exists, but heterogeneity, blinding problems, and protocol dependence keep this promising rather than established.
Editorial note
This is the most-cited quantitative summary of binaural-beat research. It supports a cautious “may help some people in some contexts” framing — particularly for anxiety and relaxation outcomes — while its own heterogeneity statistics warn against strong claims.
Why we cite it: it sets the evidence ceiling for our binaural beats guide and the copy in our interactive tool: worth trying, cheap, low risk, not a treatment.
