A note that is ninety-two octaves below B-flat. Hearing the brown noise makes people have an uncontrolable urge to shit their pants. The brown noise was once used in a episode of South Park.
''Hey man, did you hear about the musician who accidentally played the brown noise? Yeah, the entire audience shit their pants.''
