According to research by the National Sleep Association - White noise works by reducing the difference between background sounds and a "peak" sound, like a door slamming, giving you a better chance to sleep through it undisturbed. If you have difficulty falling asleep or staying asleep, creating a constant ambient sound could help mask activity from inside and outside the house.
In your bedroom, white noise can be created by a sound conditioner, a fan or an air purifier, anything that is a consistent and soothing backdrop throughout the night.
This application simulates background sounds. It contains: white noise, pink noise, the sound of a dishwasher and other household sounds. There are also sounds of city traffic and sounds of the forest.
You might want to experiment with the volume and type to find the white noise that works best for you, or if you have a sleeping partner, the sound that works for both of you.
