Deep Delta Sleep — 1.2 Hz

A slow, deep delta soundscape built around a 1.2 Hz pulse, the slow oscillatory range often linked with deep sleep. Two gentle binaural pairs (90.0 Hz and 91.2 Hz, with a lower 45.0 Hz and 46.2 Hz layer) settle into the same calm 1.2 Hz beat, supported by a soft 22.5 Hz movement, a warm 174 Hz and 200 Hz harmonic bed, and a smooth pink-noise field that drifts slowly from side to side.

As a Bisochronic design, it works for headphones and speakers alike. This 20-minute version is a focused space for winding down before bed, easing into deep rest, or quietly unwinding during the day. Keep the volume low and comfortable, use headphones if you can, and let the sound carry you. This is sound for rest and relaxation, not a substitute for professional care.
