Pink-noise ladder

Calibrated, capped, gentle pink noise

Pick your week. The ladder plays a steady pink noise at the target relative level for that week. Start with your phone or speaker volume low — the level should be comfortably below the loudest sound in the room, never the loudest. Discomfort during a session is fine; pain is not.

Calibration

  1. 1. Set your device volume to about a third.
  2. 2. Start the ladder at week 1. Sit at normal listening distance.
  3. 3. Adjust device volume so the noise is just audible above the room — not loud.
  4. 4. Use this device volume as your reference for the whole programme.
  5. 5. As weeks progress, the in-app level rises while your device volume stays the same.
