A recent study published by researchers at MacEwan University, Edmonton, AB, Canada has proposed that infrasound sound waves at frequencies below human hearing may be a significant factor in the experience of paranormal phenomena. The research focused on the relationship between low-frequency sound waves and the human brain's interpretation of environmental stimuli as ghostly or supernatural. This study was conducted in various reportedly “haunted” locations, including historic buildings and rural areas known for frequent paranormal claims. Researchers aimed to measure the presence of infrasound and correlate it with reports of unusual sensations, apparitions, or feelings of unease. This work took place over several months, employing sensitive audio equipment coupled with witness interviews to gather comprehensive data. The goal was to determine whether infrasound could produce physical and psychological effects that mimic experiences traditionally attributed to hauntings or poltergeist activities.
Key details from the study reveal that infrasound at around 19 Hz may induce feelings of anxiety, chills, and a sense of a presence, which align with many eyewitness descriptions from hauntings. Witness accounts involved sensations of cold spots, floating sensations, or seeing shadowy figures, all occurring within environments also tested for low-frequency sound. While some participants reported visual oddities or emotional reactions during periods of heightened infrasound, the study acknowledges variability and does not claim that infrasound fully accounts for all paranormal experiences. Critics point to the challenge of isolating variables in historic and atmospheric conditions where electromagnetic and psychological factors may also play roles. However, the evidence supports the hypothesis that infrasound can generate physiological responses typically associated with ghostly encounters, underpinning some traditional folk narratives. This lends a scientific dimension to what was previously regarded as purely subjective or supernatural.
The concept that infrasound may contribute to perceived hauntings fits within broader paranormal research intersecting geophysics and human sensory perception. Infrasound has been documented near natural sources such as earthquakes, volcanic activity, and wind interacting with environmental features, all of which have been linked anecdotally to haunted sites. Historical buildings with complex acoustics may inadvertently amplify these frequencies, potentially triggering subconscious fear and hallucinations. This explanation complements existing categories in paranormal studies, distinguishing between apparitions caused by psychological or environmental factors and those with potentially inexplicable origins. It also aligns with similar findings related to electromagnetic field fluctuations and carbon monoxide poisoning, which can induce altered states of consciousness. Overall, this study adds to a nuanced understanding of how natural phenomena can influence human experience and belief in the paranormal, encouraging further interdisciplinary investigations in this field.
