Waterfall sounds
The dense, unbroken roar of a waterfall: full-range like white noise but with a deep low thunder underneath. Falling water is one of the closest natural sounds to broadband noise.

Why a waterfall sounds like noise
A waterfall is millions of droplets and air bubbles hitting water and rock at once. Each impact and each oscillating bubble makes a tiny click or ping, and so many overlap that they blur into a continuous roar covering almost the whole audible range. The heavy mass of water landing adds a deep rumble.
That makes waterfall sound a natural broadband masker, somewhere between white and pink noise, with more bass.
Waterfall vs white noise
Both cover the whole spectrum. Ours slopes down gently and adds a low rumble, so it is softer at the top than white noise while masking just as broadly. It is a good choice if you want strong masking that still sounds like nature.
Questions
Is waterfall sound good for sleep?
Yes for many people. It is steady with no sudden events, which is what makes noise useful for sleep. Keep it at a modest volume.
Is waterfall sound the same as white noise?
Close. It covers the same range but has less treble and more bass, so it sounds fuller and more natural.
Waterfall or river sounds?
A waterfall is a dense, constant roar for masking; a river or stream is lighter and more detailed, better for relaxing.
