The name for a fictional/hypothetical sound frequency (or pitch or note) having the property that it causes loss of bowel control, and thus involuntary defecation, in humans. No actual note/sound frequency having this property has been identified as of May 8, 2008. The term is distinct from "brown noise". In science, Brownian noise, also known as "Brown noise" or "red noise", is the kind of signal noise produced by Brownian motion. An example of Brownian noise is the sound a television speaker makes when the screen goes to static.
