Delta Isochronic Tones
Nine hours of delta isochronic tones with a low delta binaural beat, for a full night of deep sleep.

About this soundscape
This is nine hours of delta isochronic tones, a single tone switching on and off in a steady pattern. Beneath it runs a low delta binaural beat at 1.5 Hz, built on base frequencies between 76 Hz and 80 Hz, right at the bottom of the delta range.
It's made to play through a whole night of sleep, though some people use it for meditation or an evening wind-down. Headphones bring out the binaural layer, while the isochronic pulse comes through either way.

How to listen
No headphones neededIsochronic tones are clear on-off pulses, so they work through ordinary speakers as well as headphones.
Keep the volume comfortableLoud enough to hear the pulse clearly, never so loud it becomes tiring.
Not while drivingThis is made to slow you down. Don't listen while driving, or if you have epilepsy or a seizure condition.
