Feb 26, 2024

In the world of soundscapes, various colors of noise are utilized for their distinct auditory properties and potential benefits. Among these, 'green noise' and 'brown noise' are lesser-known compared to their popular counterparts, white and pink noise. Each 'color' of noise has its unique frequency spectrum and use cases, and knowing the differences between them can help individuals find the sound that best suits their needs.

Green noise, often referred to as the sound of nature, is typically associated with the mid-frequency sounds of a lush forest. It encompasses a range of frequencies that the human ear finds calming and restful. Green noise is less about a strict technical definition and more about its linkage with the natural environment, invoking a feeling of balance and tranquility. Therefore, it is commonly used for relaxation, meditation, and masking distracting sounds in day-to-day life.

Brown noise, on the other hand, is named after the Brownian motion (or random particle movement), and it has a deeper, rougher tone compared to white or pink noise. Its power density decreases by 6 decibels per octave with increasing frequency (double the rate of pink noise), which makes it rich in lower frequencies. Brown noise is often likened to the low roar of a waterfall, a strong wind, or the deep rumble of thunder. This type of noise is considered excellent for sleep, easing into deep relaxation, and
