Infrasound Plus ELF Electromagnetic Waves Below 2o Hz Observed.
Submitted 11/26/03 by Jim Hale for the VGHRS

My home-made infrasound detector/monitor indicated the not unusual presence of infrasound at the Museum. A steady flow of traffic on Main Street (about 200+ feet away) generates a low level but fairly constant rumble in both audible and infrasonic frequencies that seem to resonate well with the high-ceiling rooms, large windows and wooden floors.

An unexpected discovery relates to the electromagnetic carrier wave signal that is being transmitted through the railroad tracks some 100 feet in front of the building. This signal was detected while using the Hummer on our preliminary trip.
I recorded a few seconds of that signal with the Hummer plugged into the mic input of my digital voice recorder. Spectrum analysis with the PAS Analysis Center software shows two frequency peaks at 523 Hz and 800 Hz. (Note that these signals would be considered within the audio frequency range but they are actually being generated as electromagnetic waves - the Hummer converts the original EM signal to audio.)

However - if my readings are correct, according to spectrum analysis there is also a very strong mixture of ELF frequencies (well below 20 Hz) that is emanating from those train tracks! This makes for a very unusual EMF field. Again, these frequencies are being generated as electromagnetic waves and they are in the ELF range (Extreme Low Frequencies) that relates to human brainwave activity. I'll try to confirm the ELF signal, determine its range and find if there is an accompanying infrasonic sound wave being generated from the track as well.

Do all railroad tracks emit such a signal?
Does anyone know any stories that involve trains and ghosts?
