We examined a minimal model for an active colloidal fluid in the form of self-propelled Brownian hard spheres that interact purely through excluded volume. Using simulations and analytic modeling, we ...

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 ...

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 ...
