Continuous Brown Noise (25 Minutes) | Sleep Aid | Relax | Focus

You have probably heard of White Noise, but what about Brown Noise? In another noise masking or sound masking process, Brown Noise (also sometimes referred to as red noise) has higher energy at lower frequencies and is deeper and stronger than white noise. It can resemble strong waterfalls; a low river roaring; or, soft, rumbling thunder. You can use it for relaxation, as a sleep-aid, for noise-blocking & even for improved focus.
