10 Hours | Hear one of our most popular sounds, Pink Noise, paired with a more recent sound of a Tiny Waterfall. Pink Noise is darker and emphasizes lower frequencies than white or brown noise. This creates a strong wall of sound to drown out background noise. Tiny Waterfall is the sound of a baby waterfall trickling down a flowing stream that weaves its way through the woods. The air is cool and fresh, the moon casts down through the trees onto the soft forest floor where moss and leaves reside, and nearby a small family of deer are sleeping. Below the water, a few minnows and small fish rest underneath a large rock. All is quiet and peaceful in the forest, as the world falls asleep once again.
