The "ghost frequency," a low-frequency sound around 18.9 Hz, has been linked to reported paranormal experiences and feelings of unease.
Vic Tandy's research into the "ghost frequency" has significantly contributed to understanding the relationship between infrasound and reported paranormal experiences. In the early 1980s, Tandy, a British engineer and lecturer, had an unsettling experience in his laboratory where he felt a ghostly presence and observed a gray figure in his peripheral vision. This led him to investigate the phenomenon scientifically.
Tandy discovered that a newly installed extractor fan was emitting a low-frequency sound at approximately 18.98 Hz, which is close to the resonant frequency of the human eye. This frequency is categorized as infrasound—sound waves that are below the range of human hearing but can still affect the body. He noted that this infrasound could cause physical sensations such as anxiety, chills, and even visual distortions, potentially explaining many ghost sightings and feelings of unease reported in haunted locations.
In subsequent experiments, Tandy demonstrated that exposure to infrasound could lead to unusual experiences. For instance, during a concert where some pieces included infrasound, about 22% of participants reported feeling uneasy or experiencing chills when exposed to these low frequencies. This aligns with findings from other researchers who have linked infrasound to eerie sensations and perceptions of apparitions.
Tandy's work has provided a scientific basis for understanding how environmental factors can influence human perception and emotional responses, particularly in locations rumored to be haunted. His findings suggest that what some interpret as supernatural encounters may have natural explanations rooted in acoustics and human physiology.
Vic Tandy's experiments revealed that certain environments with high levels of infrasound could lead to visual distortions and feelings of dread, which he initially attributed to supernatural occurrences37. This phenomenon has been linked to the resonant frequencies of human organs and structures, such as the eyes, which may contribute to visual hallucinations when exposed to specific low-frequency sounds.
Scientific Reasons
Scientific investigations into reportedly haunted locations have identified several natural phenomena that may explain ghostly experiences.
Infrasound: Low-frequency sound waves, particularly around 18-19 Hz, have been detected at elevated levels in many "haunted" areas. Research indicates that exposure to infrasound can induce feelings of unease, anxiety, and even visual hallucinations. For instance, studies have shown that when participants were exposed to infrasound during music performances, about 22% reported unusual sensations such as chills or feelings of dread.
Carbon Monoxide Poisoning: This can lead to hallucinations and feelings of dread. Elevated levels of carbon monoxide can cause symptoms similar to those reported in haunted locations, including confusion and visual disturbances.
Electromagnetic Field Fluctuations: Variations in electromagnetic fields may stimulate the temporal lobe of the brain, leading to sensations akin to paranormal encounters. Some studies suggest that these fluctuations can affect brain activity in ways that mimic ghostly experiences.
Psychological Factors: Suggestibility and expectation play significant roles in how individuals perceive their environments. People who believe they are in a haunted location may be more likely to misinterpret ambiguous stimuli as supernatural.
Sleep-Related Phenomena: Conditions like hypnagogic hallucinations (hallucinations occurring while falling asleep) and sleep paralysis can contribute to experiences often described as ghostly encounters. These phenomena can create vivid and frightening sensations that are easily mistaken for paranormal activity.
Researchers utilize various scientific instruments, such as electromagnetic field detectors and infrared cameras, to study claims of paranormal activity. While the findings do not provide evidence for the existence of ghosts, they offer rational explanations for many reported supernatural experiences, suggesting that environmental factors and psychological responses can significantly influence perceptions of hauntings.
The Ghost Frequency (Band)
The Ghost Frequency was a British rock band formed in Spring 2005. They gained recognition for their unique blend of electropop and post-hardcore influences, drawing comparisons to bands like The Rapture and At the Drive-In1. The band consisted of members Doran Edwards (lead vocals, programming), Barney Ward (synthesizers), Anthony Murphy (guitars), Ross Colgan (guitars, bass, synthesizers), and Jason Adelinia (drums).
Their debut single, "Nightmare," was released in August 2007, followed by a second single titled "Never Before Have I Seen a Man Alive That Looks So Exactly Like a Skeleton" in December of the same year. Both singles were released on limited edition vinyl and received airplay on platforms like BBC Radio 1 and MTV21. The band's only album, Electric Teeth, was released in 2010 under the Pedigree Cuts label.
Live Performances
The Ghost Frequency toured extensively in the UK, supporting acts such as Hadouken! and performing at festivals like the Evolution Festival in 2008.
The "ghost frequency" is identified as approximately 18.9 Hz, which falls into the category of infrasound—sounds that are below the threshold of human hearing (20 Hz). While humans cannot consciously hear these sounds, they can still perceive them physically, often resulting in sensations of discomfort, fear, or paranoia.
Production
The technique involves utilizing two acoustical sources that emit sound waves at frequencies above 20 Hz. By carefully adjusting the frequencies of these sources, their difference can be set to a range below 20 Hz (ideally between 5 Hz and 7 Hz). This frequency difference allows for the creation of infrasound in the area where the sound waves intersect. Follow the following steps:
- Select Acoustical Sources:
- Choose two directional transducers capable of producing sound at high frequencies. Common choices include pneumatic whistles or electrical transducers designed for low-frequency output.
- Frequency Generation:
- Use oscillators to generate two sound waves:
- Transducer 1: Set to a frequency (e.g., 30,000 Hz).
- Transducer 2: Set to a slightly lower frequency (e.g., 29,995 Hz).
- The difference between these frequencies is 5 Hz, which falls within the desired range for producing infrasound.
- Use oscillators to generate two sound waves:
- Phase Modulation:
- Implement a phase modulator that can control the phase of one of the sound waves. This modulator should be driven by a low-frequency signal (around 5 Hz) to create variations in the phase of the sound wave emitted from one transducer.
- The phase modulation causes constructive and destructive interference between the two sound waves, leading to areas of compression and rarefaction.
- Intersection of Waves:
- Position the transducers so that their emitted sound waves intersect at a specific point in space. The intersection creates regions where the combined effects of both waves generate infrasound.
- The resulting infrasonic wave can be described as an "infrasonic warble," as it varies between frequencies due to the modulation.
- Equipment Setup:
- Use power amplifiers to boost the signals from each transducer before they are emitted.
- Ensure that both transducers are calibrated to maintain consistent amplitude while allowing for phase shifts caused by the modulator.
- Monitoring and Adjustment:
- Utilize monitoring equipment such as microphones sensitive to low-frequency sounds to detect the presence and intensity of infrasound at the intersection point.
- Adjust the frequencies and modulation parameters as necessary to optimize infrasound production.
