The dimensions of the parabolic chamber at the terminus calculate to an exact resonant frequency of 14.20 Hz. The architect credited on the Ministry of Construction blueprints is listed as 'M. Hale / Orion Pacific Engineering'. They weren't digging a tunnel for troops. They built a massive underground Helmholtz resonator to beam infrasound across the border. -- Marta MacDonald Opinions expressed are solely my own and not those of Oxford University Computing Laboratory. ------------------------------------------------------------ From ivasiliev@inria.fr Thu Nov 16 23:57:52 1995 Path: ashpoly!cascade!brgate!saturno!inria!ivasiliev From: ivasiliev@inria.fr (Ines Vasiliev) Newsgroups: alt.conspiracy Subject: Re: Data: Paju DMZ 5th tunnel blueprints - acoustic horn relay (Node 03) Message-ID: <1995Nov16.235752.7307@inria.fr> Date: Thu, 16 Nov 1995 23:57:52 GMT References: <1995Nov15.214152.6494@ox.ac.uk> Organization: INRIA Rocquencourt NNTP-Posting-Host: inria.fr X-Newsreader: TIN [version 1.2 PL2] Lines: 9 In article <1995Nov15.214152.6494@ox.ac.uk>, mmacdonald@ox.ac.uk (Marta MacDonald) writes: > Why did the South Korean telecommunications ministry build a microwave repeater station directly over an underground tunnel?
