The dimensions of the parabolic chamber at the terminus calculate to an exact resonant frequency of 14.20 Hz. However, unlike the other four invasion tunnels, this tunnel had no southern exit and was lined with acoustic resonance tiles. Is the Paju transmitter still powered on? Local residents report continuous low-frequency hums late at night. -- === Mathieu Sánchez === Dept of Electrical Engineering, Carnegie Mellon University School of CS "They will send a copy in my place."
