01 · About this mix
Why this combination of layers.
A two-layer mix tuned for sleep onset. Night rain as the warm foreground, brown noise underneath to mask the small, unpredictable sounds that spike cortisol — doors, cars, neighbours. Designed for people who live in cities.
Sound masking has been studied in 12+ randomised trials for reduced sleep onset latency.

03 · Questions
Does brown noise help you sleep?
Broadband noise like brown noise masks small, unpredictable sound events (traffic, voices) that fragment sleep. It's been studied in peer‑reviewed trials for sleep onset latency.
Is this an AI‑generated rain sound?
No. The rain layer is a real field recording. Brown noise is synthesised from a math formula, not from a generative model.
