How it works
Binaural
Two tones, one in each ear. Headphones. Binaural-beat entrainment is not settled science.
Beta
200 Hz in each ear until you choose a pulse
Waves
BetaA steady 12 Hz gap. Beta names the faster rhythms recorded while awake and occupied.
AlphaA steady 10 Hz gap. Alpha is the quieter awake range, talked about during an easy task.
ThetaA steady 6 Hz gap. Theta is the slower, drowsy range, talked about while winding down.
DeltaA steady 2 Hz gap, the slowest of the four. Delta names the slowest rhythms recorded in deep rest.
These names come from rhythms recorded from the scalp. The sound you hear is only the gap between the ears. Whether that gap changes a rhythm is not settled science.
Programs
ArriveSitting down. The pulse eases from 10 Hz toward 8 Hz.
ClearA task that needs attention. Stays near the top of the range, between 11 and 12 Hz.
OpenReading or an easy task. A steady awake pulse around 10 Hz.
UnwindAfter the day. Moves from 10 Hz down to 6 Hz.
DriftLetting attention wander. Slows from 7 Hz to 5 Hz.
StillA long pause, eyes closed. Holds a slow pulse around 4 Hz.
NightIn bed, lights low. The slowest pass, from 3 Hz down to 2 Hz.
ReturnComing back after a rest. Rises from 4 Hz to 10 Hz.
SoftNeither busy nor asleep. A middle pulse around 8 Hz.
DawnStarting the morning. Rises from 6 Hz to 12 Hz.
Each program moves the gap between the ears along its curve. Use headphones, one tone in each ear.
