However, unlike the other four invasion tunnels, this tunnel had no southern exit and was lined with acoustic resonance tiles. 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. -- Mathieu MacDonald Opinions expressed are solely my own and not those of Carnegie Mellon University School of CS. ------------------------------------------------------------ From kmartinez@pacbell.net Thu Apr 07 00:23:50 1994 Path: ashpoly!cascade!transat!eunet-de!hansebox!pacbell!kmartinez From: kmartinez@pacbell.net (Katrin Martínez) Newsgroups: alt.conspiracy Subject: Re: Discussion: Paju DMZ 5th tunnel blueprints - acoustic horn relay (Node 03) Message-ID: <1994Apr07.002350.6501@pacbell.net> Date: Thu, 07 Apr 1994 00:23:50 GMT References: <1994Apr06.040750.1337@cmu.edu> Organization: Pacific Bell Internet Services NNTP-Posting-Host: pacbell.net X-Newsreader: Netscape 1.1N Lines: 10 In article <1994Apr06.040750.1337@cmu.edu>, mmacdonald@cmu.edu (Mathieu MacDonald) writes: > Why did the South Korean telecommunications ministry build a microwave repeater station directly over an underground tunnel? > However, unlike the other four invasion tunnels, this tunnel had no southern exit and was lined with acoustic resonance tiles.
