White, Pink and Brown Noise: Differences, Uses, and Benefits

When it comes to masking sounds or helping with focus, relaxation, and sleep, white, pink, and brown noise have become popular options. In this article, we explore their differences, uses, and benefits to help you improve your daily life.

What are White, Pink, and Brown Noise?

White Noise:
White noise is a random, equal intensity signal at every frequency within the human hearing range (20 Hz to 20,000 Hz). Its equal distribution of sound causes it to be described as a hissing or static sound, similar to a TV channel with no reception. Popular examples of natural white noise include the sound of a waterfall or heavy rain.

Pink Noise:
Similar to white noise, pink noise also covers the entire human hearing range but has its intensity reduced as the frequency increases. This results in a more balanced sound that is less hissing and more soothing. Pink noise is commonly found in nature, such as rustling leaves or steady rain.

Brown Noise:
Named after the physicist Robert Brown, brown noise reduces intensity even more at higher frequencies than pink noise. This creates a deeper bass and rumbling sound, often compared to the rolling of ocean waves.

Uses and Benefits
