There are several different types of noise, each with unique characteristics and benefits: White Noise – Equal intensity across all frequencies, creating a "static" sound. Common for masking background noise and improving sleep. Pink Noise – More balanced, with lower frequencies emphasized, making it softer and more natural (e.g., rustling leaves, steady rain). Brown (Red) Noise – Deeper and bass-heavy, like distant thunder or a waterfall, often used for relaxation. Blue Noise – Higher frequencies emphasized, making it sharper (less common for sleep or relaxation). Violet Noise – Even more high-frequency emphasis, sounding like a sharp hiss. Gray Noise – Balanced for human hearing, with different frequencies adjusted to sound equally intense. Black Noise – Often defined as silence or the absence of sound, but in some cases, it refers to random noise with moments of quiet. If you're specifically looking for a machine that produces Black Noise, it may be harder to find since many sound machines focus on white, pink, or brown noise.
