Using Geophones To Detect Paranormal Phenomena
A geophone is a device designed to detect and measure ground movements, such as vibrations or seismic activities. Based on technology originally used in fields like oil exploration and seismology, the geophone is also used during paranormal investigations, most commonly in the form of the geophone built into the EDI+ multi-tool, a popular ghost hunting device that combines the geophone function with other sensors.
Although similar to seismographs, geophones are not the same device and serve different purposes. A geophone is a portable device designed for easy deployment in various locations, capable of detecting and measuring ground movement or movement in the surface on which it is placed. On the other hand, a seismograph, or seismometer, is an instrument used primarily by geologists and seismologists for scientific research into the Earth's movements and requires a more sophisticated setup to accurately detect and record earthquakes, tremors, and other types of seismic activity.
Professional geophones used industrially usually consist of a spike that is planted into the ground for stability and connected to recording equipment via cables. The types of geophones used by paranormal investigators tend to be simplified, standalone versions of the industrial geophone, designed for ease of use and portability. Paranormal investigators often use specialised geophones designed for the paranormal field, which balance sensitivity with user-friendly interfaces.
Regardless of the form they take, the fundamental purpose of all geophones is to detect vibrations and convert them into an electrical signal in order to alert the investigator as to the intensity of the vibration through a quantifiable display of lights or sounds in real time. More advanced geophones may also be able to measure and record their readings. The sensitivity of a geophone allows investigators to pick up on minute knocks, bangs, and movements that might otherwise go unnoticed by human senses.
In the context of paranormal investigations, investigators primarily use a geophone to detect and document subtle vibrations and movements that could indicate paranormal activity, especially those that might be too slight for the human body to feel. It's also useful over long distances, as it allows investigators to place the device in one area and monitor for activity from afar, reducing the chances of inadvertently influencing the readings through their own movements.
Some investigations involve geophones in attempts to communicate with spirits. Ghost hunters might ask entities to show their presence by causing the device to trigger in response to questions.
Theoretically, if ghosts or spirits are capable of interacting with the physical world, there are several ways they might cause vibrations detectable by a geophone during paranormal investigations. In its most basic form, this interaction could include moving objects, causing knocks or footsteps, or generating other sounds. These actions would produce vibrations in the surrounding materials and surfaces that a geophone could detect.
Some believe that spirits communicate or make their presence known through low-frequency vibrations. These are sounds that are not audible to the human ear, known as infrasound. These sound waves can cause objects to vibrate, and although the sound itself might not be directly audible to investigators, the resulting vibrations could be picked up by a geophone.
Like any investigative tool, a geophone comes with its own set of challenges and potential pitfalls. The most significant of these pitfalls is the tendency to misinterpret data. Investigators should be careful to correctly distinguish between vibrations caused by paranormal phenomena and those resulting from mundane sources. Environmental factors, such as traffic, footsteps, or even changes in building structure, can produce vibrations that might be misinterpreted as paranormal, as can the movements of the investigators themselves.
Distinguishing between paranormal vibrations and those resulting from mundane sources can be made easier by controlling the environment around the geophone as much as possible. This might involve minimising movement in the vicinity, accounting for known sources of vibrations, and selecting locations strategically based on the investigation's focus.
It's important to note that while the geophone can signal the presence of unusual vibrations, it does not, in itself, provide direct evidence of paranormal activity. The lights indicating the strength of the vibration offer insights into the intensity of the detected movements but do not explain their source. Therefore, while a geophone can indeed detect vibrations, attributing these exclusively to paranormal causes without ruling out all possible natural explanations can lead to misinterpretation of the evidence.
