14 Hz binaural beats
Low beta. Fast enough to feel like working rather than resting, slow enough to stop noticing after the first minute.
14 Hz is at the bottom of the beta band, the range associated in EEG with active concentration. As a listening experience it is the point where a binaural beat stops feeling like a slow sway and starts feeling like texture — present, but not the flutter you get in the gamma range.
Why it pairs with a noise bed
A bare beta beat is more noticeable than a slow one, and over fifty minutes that gets tiring. Brown noise underneath does two things: it covers the room, and it gives the beat somewhere to sit so it stops being the most interesting thing in your ears. This page defaults to that pairing for exactly that reason.
Block lengths that work
| Block | Suits | Note |
|---|---|---|
| 25 minutes | Admin, email, small tasks | The pomodoro default |
| 50 minutes | Writing, coding, analysis | Long enough to pay back the warm-up |
| 90 minutes | Deep sessions | Take a real break after, not another block |
Beta and alertness, honestly
The band is named after a measured brain rhythm; the assumption that a 14 Hz sound promotes it is the entrainment hypothesis, which is not well supported for practical outcomes. Several attention studies find no benefit, and a few find a cost. What is left is a wordless, predictable sound and a timer — genuinely useful, and a smaller claim.
Questions
Is 14 Hz good for studying?
It is a common choice for long blocks. See the study player, which is built around the same idea with a 50-minute default.
Is beta better than alpha for work?
No evidence establishes either. Beta feels more active; alpha feels calmer. Try both for a week each rather than switching daily.
Why does it sound rougher than 6 Hz?
Faster beats are perceived as texture rather than motion. Above about 20 Hz the roughness increases further — see 20 Hz.
