Infrasound Explains Haunted Feelings

What's happened

Recent studies have shown that infrasound from old pipes and ventilation systems can cause feelings of irritation, unease, and elevated cortisol levels, which may be mistaken for paranormal activity. The research suggests that inaudible low-frequency sounds are influencing human perception and mood, especially in old buildings.

Infrasound is shifting the understanding of paranormal sensations

This research confirms that infrasound at around 18.9 Hz can cause irritability and increased cortisol, which are associated with feelings of unease and being watched. These effects occur even when individuals cannot hear the sound, indicating that the body responds subconsciously.

The studies demonstrate that old pipes and ventilation systems produce infrasound, which can trigger bodily discomfort and mood shifts. This challenges the traditional attribution of hauntings to supernatural causes, suggesting instead that environmental factors are responsible.

This will likely lead to a reassessment of reported paranormal experiences, especially in old buildings. It also indicates that infrasound exposure could have broader health implications if it is pervasive in everyday environments. Future research will expand the frequency range studied and explore long-term health effects, but current evidence shows that infrasound is a significant factor in perceived hauntings and discomfort.

Understanding this will help demystify many ghost stories and improve building maintenance to reduce low-frequency vibrations, ultimately improving occupant wellbeing.

How we got here

Scientists have long investigated the causes of alleged hauntings, often attributing sensations to environmental factors like magnetic fields and lighting. Recent research focuses on infrasound, low-frequency vibrations below human hearing, which are common in aged buildings and can affect mood and stress levels without conscious awareness.

Our analysis

The articles from Ars Technica, NY Post, and The Guardian all explore the impact of infrasound on human perception and mood. Ars Technica emphasizes the scientific experiments showing cortisol increases and irritation caused by infrasound, while the NY Post highlights how old plumbing can produce these vibrations, leading to false paranormal attributions. The Guardian discusses the broader implications for haunted house experiences and how infrasound may supply bodily discomfort that is mistaken for supernatural activity. While all sources agree on the effects of infrasound, Ars Technica provides detailed experimental data, whereas The Guardian offers a more contextual overview. The NY Post focuses on practical implications in old buildings. The consensus is that infrasound is a scientifically plausible explanation for many sensations traditionally attributed to ghosts, but further research is needed to understand long-term health impacts and the full scope of its influence.
