Sleep better with Raspberry Pi automated white noise

Theory Having complete silence while you sleep 😴 may seem nice, but in fact can lead to trouble if the outside environment is not also completely quiet. A cat may meow🐱, a car may honk 🚗, your upstairs neighbour can wake up for a late-night snack 🍟… All these sounds will seem louder if your room is completely quiet. The human perception of sound is nonlinear. That’s why it’s measured in decibels.
