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:
“they are brown and soft,
And liable to melt as snow.”
—Hart Crane (1899–1932)
“My note to you I certainly did not expect to see in print; yet I have not been much shocked by the newspaper comments upon it. Those comments constitute a fair specimen of what has occurred to me through life. I have endured a great deal of ridicule without much malice; and have received a great deal of kindness, not quite free from ridicule. I am used to it.”
—Abraham Lincoln (1809–1865)
