Do binaural beats entrain the brain? A systematic review (Ingendoh 2023)
The evidence is inconclusive. Of 14 EEG studies, only 5 were in line with the entrainment hypothesis, 8 reported contradictory results and 1 was mixed.
The question: Do binaural beats drive brain activity to oscillate at the beat frequency?
| Type of study | Systematic review |
|---|---|
| Who took part | 14 EEG studies |
| How much weight it carries | Preliminary |
What it found
- Of 14 published EEG studies of binaural-beat stimulation, 5 were in line with the brainwave entrainment hypothesis, 8 reported contradictory results and 1 was mixed.
- The included studies were highly heterogeneous in how beats were implemented, in experimental design and in EEG parameters and analysis, which limits comparability.
- The percept has physiological constraints: carriers must be below 1000 Hz, work best near about 400 Hz, and the beat difference can be up to about 30 Hz.
Limits
- Heterogeneity across the included studies limits comparability.
- The authors conclude the field urgently needs methodological standardization before reliable conclusions about brainwave entrainment can be drawn.

This is our plain-language reading of the paper. It is not medical advice, and one study rarely settles a question.
