From practical experience, we have learned that such white noise sounds are more effective as a lullaby for people sleep than music, tones or sing.
Sleep sounds and nature sounds make you relax and fall asleep.

HOW WHITE NOISE CAN HELP ME TO CONCENTRATE TO WORK OR EASY TO FALL ASLEEP?
Because White Noise contains different noises at different level of frequency which can cover your real surrounding noises. When you listen to White Noise, your brain understands that it can listen to only one noise and can’t recognize the other surrounding noises.
