Sound Therapy & Sleep: Latest Research on Noise Colors

Abstract visualization of brown noise with deep, smooth waveforms in warm brown and muted gray tones. The waves are denser and more pronounced at lower frequencies, symbolizing the deeper, calming sound profile of brown noise, often used to promote relaxation, focus, and sleep. The image captures the natural, rumbling quality associated with brown noise.
