But there's another frequency to try: brown noise, also called Brownian noise or red noise, which emphasizes lower-frequency sounds. It has the deepest intensity of all noises and sounds like a ...

Unlike white and pink noise, Brown noise is named for Robert Brown, the discoverer of Brownian motion, which creates the sound, Dr. Pelayo says. (For the grammatically attentive, this is why Brown ...

White noise has a flat spectrum, but the noise from the Rumbler is closer to Red or Brownian Noise. The different colors of noise have specific definitions, but the Rumbler’s output is really ...

“Brown noise is a low-frequency sound produced by the same process that causes Brownian motion (random particle motion),” Seeley explains. “Brown noise essentially describes the use of ...

There have been several proposals on how to reduce this Brownian noise: apart from the brute-force approach of cooling the cavity to cryogenic temperatures, novel mirrors and other geometries have ...
