8-Hour Brown Noise/Ruido Marron

Sink into 8 hours of brown noise, known for its deep, low‑end frequencies that drop about 6 dB with each octave. This creates a warm, rolling sound similar to ocean waves or distant thunder. Because brown noise emphasizes bass frequencies and removes the sharper highs, it can be especially effective for masking loud environmental sounds, supporting sustained focus, easing anxiety, and promoting deeper relaxation.
