Why rain is so easy to sleep to
Rain is a sound most of us connect with staying in, with nowhere to be. It's steady without being flat: thousands of tiny drops blend into a soft wash with just enough texture to keep it from sounding mechanical.
Like a fan, it fills the silence so that sudden noises stand out less, but it feels a little more natural and a little less like an appliance.
Rain and a fan, together
The fan gives you a smooth floor of sound and the rain adds detail on top. In Fan of Sleep you can turn both on and set the rain's volume in the mixer, so it sits just where you want it.
Want something heavier?
If gentle rain is too light, try the thunderstorm, with deeper rain and the odd roll of thunder.
