Pick a noise color. Pick a binaural beat. Play them together. Tune the volumes until the layer underneath feels right.
Use stereo headphones — binaural beats require both ears.
Tip: keep the binaural beat quieter than the noise — it's meant to sit under, not over. Start binaural around 20–30%, raise the noise until the whole thing feels like a room you want to be in.
Honest caveat: the research on binaural beats is mixed. Pink noise has the strongest evidence for focus and sleep. Treat this as a tool that either works for you or doesn't — your brain gets the final vote.
