Signal Theory

How it works

SEC 02 / METHOD

When each ear receives a slightly different frequency, your brain perceives a beating tone equal to the difference — the "binaural beat." At 10 Hz (Alpha), this nudges your brainwave activity toward a calm, receptive state that researchers associate with improved retention and reduced mind-wandering. Add a brown noise floor and you get a full focus environment without touching your actual content.

  1. Start your audiobook, podcast, or lecture in Audible, Spotify, YouTube — anywhere.
  2. Open BinauralMix in a second tab or window.
  3. Pick a focus preset, put on headphones, and press Play.
  4. Adjust the noise level and binaural blend until it feels right. Share the link when you find your stack.

Headphones are required — the binaural effect only works when each ear hears a different frequency.

Research: Binaural beats show a medium, significant effect size for anxiety reduction and cognitive enhancement (Garcia-Argibay et al., 2019).

Binaural beats require stereo headphones — one frequency per ear. These are what we'd pair with BinauralMix.
