White Noise

White noise contains all frequencies at equal intensity. It effectively masks disruptive background sounds like traffic or talking, making it excellent for focus and concentration in noisy environments.

Pink noise is deeper than white noise, with reduced high frequencies. It mimics the sound of steady rain or leaves rustling. Research suggests pink noise can increase deep sleep stability and improve memory consolidation.

Brown noise (or Red noise) is even deeper, resembling a distant waterfall or low thunder. Its significant rumble is incredibly soothing for calming anxiety and quieting a racing mind (ADHD).

Green noise focuses on the mid-range frequencies found in nature. It sounds like a forest breeze or ocean surf. It's the perfect balance for creating a restorative atmosphere for relaxation.
