What's Happening?
Recent research conducted by Rodney Schmaltz, a psychologist at MacEwan University, suggests that infrasound waves, which are inaudible to humans, may contribute to feelings of unease often attributed to ghostly presences. Infrasound, defined as sound at frequencies
below 20 Hz, can be emitted by old buildings through their boilers, pipes, and plumbing. Schmaltz's study, published in the journal Frontiers in Behavioral Neuroscience, involved experiments where participants walked through a haunted house attraction with infrasound speakers. The results indicated that participants moved faster and felt more unsettled when infrasound was present. Further tests with 36 volunteers listening to music, with and without infrasound, showed increased stress responses, as evidenced by higher cortisol levels in saliva, when infrasound was played.
Why It's Important?
This study provides a scientific explanation for some experiences traditionally attributed to supernatural phenomena, potentially shifting public perception of haunted locations. By identifying infrasound as a factor that can influence mood and stress levels, the research offers insights into how environmental factors can affect human psychology. This understanding could impact the tourism industry, particularly businesses that capitalize on haunted attractions, by providing a scientific basis for the eerie sensations visitors experience. Additionally, it highlights the importance of considering environmental and psychological factors in understanding human experiences, which could influence future research in psychology and neuroscience.
What's Next?
Further research is needed to determine the prevalence of infrasound in popular haunted locations and whether it consistently correlates with reports of ghostly experiences. This could involve measuring infrasound levels in various settings and examining their impact on visitors' perceptions. If infrasound is confirmed as a significant factor, it may lead to changes in how haunted attractions are marketed and experienced. Additionally, the findings could prompt building inspections to identify and mitigate sources of infrasound, potentially improving the comfort of occupants in older buildings.
Beyond the Headlines
The study raises questions about the role of environmental factors in shaping human experiences and beliefs. It suggests that what is often perceived as supernatural may have a scientific basis, challenging cultural narratives around ghosts and hauntings. This could lead to broader discussions about the intersection of science and folklore, and how scientific explanations can coexist with cultural beliefs. Moreover, the research underscores the complexity of human perception and the need to consider both psychological and environmental influences in understanding human behavior.
