Brown note

The brown note is a hypothetical infrasonic frequency that, if broadcast at sufficient amplitude, would cause humans to lose control of their bowels due to sympathetic resonance. While the concept is widely circulated in popular culture, there is no scientific evidence to support its existence or the described physiological effect.

The belief in the brown note's existence likely stems from a misunderstanding of the effects of infrasound (sound below the human hearing range, typically below 20 Hz). Prolonged exposure to high-intensity infrasound can cause feelings of discomfort, nausea, dizziness, anxiety, and even visual distortions. These effects are thought to be related to the resonance of internal organs and structures, including the eyes, and the activation of the vestibular system (responsible for balance). However, the idea of a specific frequency causing involuntary bowel movements is considered a myth.

Rumors of government or military research into weaponizing infrasound, including the brown note, have further fueled the legend. However, no credible evidence supports these claims. The practical challenges of generating and focusing high-intensity infrasound, along with the lack of proven effectiveness, make it highly improbable that such a weapon has been developed.

In conclusion, the brown note remains a popular urban legend, lacking scientific validation. While infrasound can have physiological effects, the specific claim of involuntary bowel movements caused by a particular frequency is not supported by research.
