Brown Note

The brown note is a hypothetical infrasonic frequency that would cause humans to lose control of their bowels due to resonance. The name is a metonym for the common color of human feces. Frequencies supposedly involved are between 5 and 9 Hz, which is below 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. ruanth.xyz
