Exploring Brown Noise: What Hz is Brown Noise?

Jan 23, 2024

Brown noise, also known as Brownian noise or red noise, is a type of ambient noise characterized by its low frequency and dominant energy. This type of noise is named after its association with the Brownian motion discovered by botanist Robert Brown in the 19th century. Unlike white or pink noise, the power density of brown noise decreases as frequency increases, making it audibly distinct. The exact frequency range of brown noise is widely debated, as there is no definitive value for its hertz range. Brown noise is observed to primarily reside within the lower spectrum of frequencies, commonly falling between 20 Hz to a few hundred Hz. This article dives deeper into the characteristics of brown noise, its proposed frequency range, and its potential applications in daily life.
