Rain sounds differ mostly by surface and distance: rain on a tent is close and muffled, heavy rain is brighter, and distant rain is soft. Most rain sits between pink and brown noise in shape, but unlike noise it keeps moving.
The surface changes the sound
Rain on leaves, a roof, canvas or a car window each has its own character. Between 2 and 12 kHz, Rain on a tent falls 4.7 dB per octave: close, soft and muffled by the fabric. Heavy rain falls 1.3 dB per octave, brighter than most of Hush's rain.

Rain and noise colours
Most rain sits between pink and brown noise. Soft rain falls 4.4 dB per octave; by comparison, Velvet noise stays about level and Deep brown falls 3.4 dB per octave. Unlike noise, rain keeps moving, which some people find easier to listen to and others find more distracting.
Mixing the parts of the rain
Every rain sound in Hush is built from layers. Soft rain is made of drops, distant rain and background, and with Hush Plus you can set each one, for example keeping the distant rain and lowering the individual drops.
