What do different rain sounds sound like?
Rain sounds depend on what the drops hit: light rain on dirt and grass is a soft, scattered patter, rain on leaves is brighter and airier, rain on water is wide and flat, and heavy rain becomes one steady roar.

Light Rain for Sleep | Wet Meadows and a Field Track
The surface is everything. Bare ground and grass absorb the drops, so light rain on a field track sounds soft and close. Oak and other broad leaves ring a little with each drop, which gives a brighter texture. Rain over a lake spreads out into a wide, even hiss.
Intensity changes the character too. A drizzle has gaps you can hear; a steady summer downpour fills them in completely, which is why heavy rain masks noise so well.
Our rain recordings are real outdoor rain: light rain on a field track between wet meadows, the first rain on oak leaves at a field edge on the German–Polish border, and a heavy downpour on a lake shore that caught us mid-hike. They are below.
