White, Pink, & Brown Noise: The Colors of Sound and How They Hack Your Brain

In the world of audio, 'color' doesn't refer to a visual hue, but to the specific distribution of energy across the frequency spectrum. Understanding the difference between these 'noise colors' is the key to mastering your auditory environment for peak performance and relaxation.

White Noise: The Great Equalizer

Imagine the static of an old, untuned TV or radio. That's white noise. It's defined by having equal energy at every frequency. This makes it incredibly effective at masking sharp, high-frequency sounds like human speech, sirens, or crying.

• Analogy: A wall of sound where every frequency is shouting at the same volume.
• Best For: Masking office chatter, high-pitched background noise, and creating a total sound barrier. It can be intense for some listeners.
• Find it in Stillpoint: In the 'Focus' category of the sound library.

Pink Noise: Balanced and Natural

Pink noise is often considered more pleasing to the ear than white noise. Its energy decreases as the frequency gets higher. This results in a sound that's more balanced, with less high-frequency hiss.

• Analogy: A steady, gentle rainfall or the rustling of leaves. It's less harsh than white noise.
• Best For: All-purpose focus, reading, and relaxation. It's excellent for reducing the startling effect of sudden noises without being as abrasive as white noise. Many people find they can listen to it for longer periods.
• Find it in Stillpoint: In the 'Focus' category. It's a popular foundation for many custom soundscapes.

Brown Noise (or Brownian/Red Noise): Deep and Rumbling

Brown noise has even more energy concentrated in the lower frequencies. It's deeper and more rumbling than pink noise.

• Analogy: A powerful waterfall, a strong ocean roar, or distant, rolling thunder.
• Best For: Masking low-frequency noises like traffic, construction, or the hum of an airplane engine. It's a favorite for promoting deep sleep because of its soothing, non-intrusive quality.
• Find it in Stillpoint: In the 'Sleep' category. Try blending it with rain or thunder for an incredibly cozy and protective sleep environment.
