People use White Noise because it helps them sleep. But how does it work? When you’re asleep, your brain is constantly scanning and listening for sounds. If it’s too quiet, unwanted noise such as a faucet drip or police siren can interrupt your sleep. White Noise generates sounds over a wide range of frequencies, masking those noise interruptions, so you can not only fall asleep, but stay asleep. Listen to the different White Noise color sounds with our free White Noise Player and learn more about how it helps you to sleep at night.
