### 🎵 Three Types of Noise

White Noise — Covers all frequencies equally. Masks environmental sounds, great for light sleepers and tinnitus relief.

Pink Noise — Emphasizes lower frequencies for a warmer, more natural sound. Studies suggest it may improve memory consolidation during sleep.

Brown Noise — Deep, rumbling sound similar to heavy rain or distant thunder. Beloved by people who need deep focus or want to drown out low-frequency noise.
