Rain is the most universally loved sleep sound on the planet. Every culture, every age group, every kind of sleeper seems to like it. There's a reason — and it's not a coincidence that "rain sounds" is one of the most-searched audio terms on the internet.
Why rain works
Rain has the natural texture of pink noise — broad-spectrum, soft on the high end, steady but not metronomic. It's complex enough to feel "rich" but predictable enough that your brain stops paying attention to it. Add the deep cultural association of "I'm inside, it's raining outside, I'm safe and warm," and you get an audio experience that's both physiologically calming and emotionally comforting.
