Beta waves (13–30 Hz)
Beta waves, roughly 13 to 30 cycles per second, are small, fast rhythms that dominate when you are alert, concentrating, talking or solving a problem.
Presets
When beta waves appear
- Active concentration and problem-solving
- Conversation
- Stress and anxious rumination (high beta)
Beta binaural beats: what to expect
Beta beats are used for focus. Results are mixed; a steady, predictable sound may help some people concentrate simply by masking distractions. If you are anxious, beta is usually the wrong direction.
The player is set to a 16 Hz binaural beat. Headphones on for binaural mode; keep it quiet, and give it at least ten minutes.
Five rhythms, drawn to speed
13–30 Hz · Active thinking and alertness
Slower waves are larger because big populations of neurons fire in step; faster rhythms are smaller and more local. On a real EEG the trace is a mixture of all bands at once, and a "state" just means one band dominates.
Beta waves in depthBeta waves: common questions
What are beta waves?
Fast, low-amplitude brain rhythms of 13–30 Hz seen during alert, focused thinking.
Are beta waves bad?
No, they are normal during any active task. Persistently high beta is associated with stress and overthinking.
Which beta frequency is best for studying?
Most focus presets use 14–18 Hz. There is no proven best value; try 16 Hz and adjust to taste.
