Brown Note

The brown note is a hypothetical infrasonic frequency that would cause humans to lose control of their bowels due to resonance. Attempts to demonstrate the existence of a "brown note" using sound waves transmitted through air have failed.

The name is metonym for the color of human feces. Frequencies supposedly involved are between 5 and 9 Hz, which is below 20 Hz, the lower frequency limit of human hearing. High power sound waves below 20 Hz are felt in the body, not heard by the ear as sound. The only other vibrations titled with colors are the colors of noise and blue notes.

Famous quotes containing the words brown and/or note:

    in the brown baked features
    The eyes of a familiar compound ghost
    Both intimate and unidentifiable.
    —T.S. (Thomas Stearns)

    And songs climb out of the flames of the near campfires,
    Pale, pastel things exquisite in their frailness
    With a note or two to indicate it isn’t lost,
    On them at least. The songs decorate our notion of the world
    And mark its limits, like a frieze of soap-bubbles.
    John Ashbery (b. 1927)
