Brainwave frequency bands explained
Answer
Brainwave bands are conventional EEG frequency ranges used to discuss brain rhythms. In binaural audio, the same labels are reused as beat-frequency design targets — a helpful map, not a promise that consumer audio recreates lab EEG states.
Explain
| Band | Approx. Hz | Often associated with |
|---|---|---|
| Delta | 0.5–4 | Deep sleep stages |
| Theta | 4–8 | Drowsy, meditative, hypnagogic |
| Alpha | 8–12 | Relaxed wakefulness |
| Beta | 13–30 | Active thinking, attention |
| Gamma | 30+ | Binding / high-frequency research interest |

Scientific & safety notes. Binaural listening is a consumer audio experience. Distinctions used on this site: established evidence vs preliminary research vs hypothesis vs user experience. We do not claim that a frequency cures or treats medical conditions. Do not use deep-rest audio while driving or operating machinery. Keep volume comfortable.
