What's Happening?
A study conducted by psychologists Rodney Schmaltz and Kale Scatterty from MacEwan University in Edmonton, Canada, has provided a scientific explanation for the eerie feelings often experienced in old
buildings. The research suggests that infrasound, low-frequency sound waves below the threshold of human hearing, may be responsible for these sensations. The study involved participants listening to audio clips with hidden subwoofers introducing infrasound at random intervals. Participants reported increased irritability and perceived the music as sadder when exposed to infrasound. The study also measured cortisol levels, a stress hormone, which rose following infrasound exposure. These findings suggest that infrasound, produced by everyday infrastructure like traffic and ventilation systems, could be a significant factor in the unsettling atmosphere of supposedly haunted locations.
Why It's Important?
This research is important as it challenges the traditional belief that supernatural forces are responsible for the eerie feelings in old buildings. By identifying infrasound as a potential cause, the study provides a scientific basis for these sensations, which could lead to better understanding and management of such environments. The findings have broader implications for urban living, as infrasound is prevalent in cities due to various infrastructure sources. Understanding its effects on human emotions and stress levels could inform public health strategies and urban planning, potentially leading to the mitigation of infrasound pollution and its impact on well-being.
Beyond the Headlines
The study's implications extend beyond the immediate findings, highlighting the need for further research into the effects of infrasound on human health and behavior. It raises questions about the role of environmental factors in shaping human experiences and emotions, particularly in urban settings. The research also suggests a need for public awareness and policy measures to address infrasound pollution, which could improve quality of life in cities. Additionally, the study may influence the design of buildings and public spaces to minimize infrasound exposure.
