Longer than the Science screen has room for, and held to the same standard: if the research does not support it, it does not go here.

What binaural beats actually do, and what they probably do not Pooled across 22 studies the effect is medium-sized. The entrainment mechanism behind it was contradicted by 8 of 14 studies. Both are true. 17 August 2026
Binaural beats vs solfeggio frequencies 528 Hz has a trial behind it and 432 Hz has a comparison that found nothing. Both work about as well as any other music, for reasons unrelated to tuning. 16 August 2026
A binaural beats glossary, A to Z Every term you will meet in this field, defined plainly, with a note on which ones carry a claim the evidence does not support. 15 August 2026
The binaural beat frequency chart, and which rows are real 1 Hz to 32 Hz with the usual mood labels. Three rates have a study behind that exact rate. The words attached to the rest were never measured. 12 August 2026
Binaural beats for sleep, anxiety, focus, study and meditation Five use cases, graded honestly. Anxiety has the best evidence, study has almost none, and one large study found beats made a task harder. 2 August 2026
