Sleep Learning Lab
Load a document or audiobook. It is played back as speech and tone patterns. In the morning, the lab checks what you still know.
Your material
Load a document or audiobook
The lab turns it into spoken words and a tone for each important word, plays that while you sleep, then measures what you still know in the morning.
Level stays capped. What you still know is measured after you wake. A score is not proof that sleep wrote the material into memory.
Safety
Keep the level low. Stop if you notice pain, ringing, dizziness, or irritation. This is not a medical device. Headphones should start near the bottom of the slider. The slider is capped well below full device volume.
Quick test
Run a sleep test
One button picks a random science fact, hides it, and plays each word as speech plus its own tone. In the morning, write the fact before you see a related question. Either one can match.
Level stays capped. Stop if it feels harsh. A match is a result for this night, not proof that a frequency teaches.
Custom night
- 1. Load a document or audiobook.
- 2. Play it. The screen hides the words and keeps the level low.
- 3. In the morning, write what you remember before the questions appear.
