Considered the “background noise of the world”, Green Noise mimics many of the sounds occurring in nature. The frequencies you hear will remind you of rushing water, or waves crashing on the beach. Green Noise falls in the middle of the frequency spectrum a bit above Brown Noise but isn’t quite as high as White Noise. It’s used for many applications, but is particularly good at sound masking as well as calming anxious, running thoughts. Many of my listeners use it for sleep, while others use it to block out distractions while studying or working.
