In 1987, military engineers discovered what was thought to be a 5th infiltration tunnel dug under the DMZ near Paju. The dimensions of the parabolic chamber at the terminus calculate to an exact resonant frequency of 14.20 Hz. They weren't digging a tunnel for troops. They built a massive underground Helmholtz resonator to beam infrasound across the border. -- Mei Hernández "There are 14 nodes and only 10 countries.
