MESA: Multifrequency Energy Sensor Array
Haunt phenomena have been described as anomalous visual,
auditory, or tactile experiences; sensed presences, sudden onset of emotional
experiences (fear, sadness, depression, and anger), erratic functioning of
electrical or mechanical equipment, and object movement in certain environments.
MESA
is a portable data acquisition and analysis system that simultaneously
measures a variety of energies commonly associated with haunt
phenomena, and has been used at over 150 survey sites. At
present, the system collects data on incident infrared, visible, and
ultraviolet light intensities; natural and artifically generated electromagnetic fields, gamma ray
radiation, galvanic skin response of a human subject, infrasound, and
vibration. MESA researchers also deploy digital still and
video cameras, a unique two-camera system connected to a magnetometer, as well as audio
recording - all to document haunt phenomena.
We continue to seek out locations purported to have haunt and poltergeist activity.
The idea that became MESA was first conceived of by Tim Harte in 1981. Over a delicious Godfather's pizza
shared with technically-minded high school pal David Black, Tim
presented an idea to "wire up" a room with a variety of energy sensors,
record their output in a computer and analyze the results. In
1994 Tim asked Dave to design and build it. MESA was first
realized using a compact laptop computer with custom A/D hardware,
sensors and
software. Soon afterwards Mike Hollinshead joined the group, contributing
a unique vibration sensor, community web site (now Paranormal House), and
much more. Since MESA's inception many improvements have been
made - primarily through the generosity of others in donations of
equipment, new ideas and encouragement. We kindly thank you all!
We are available for investigations, lectures or
presentations, and documentary film projects.
