Study finds infrasound the likely horror in hauntings
A recent study suggests that infrasound, or sound waves below the range of human hearing, may contribute to feelings of unease often associated with hauntings. Conducted by researchers at MacEwan University, the study found that participants exposed to infrasound reported higher irritability and elevated cortisol levels, indicating stress. This research provides a scientific explanation for why certain environments, like old buildings, can evoke discomfort without any visible cause.
- ▪The study was published in Frontiers in Behavioral Neuroscience.
- ▪Participants exposed to infrasound reported higher irritability and lower interest in music.
- ▪Cortisol levels, a marker of stress, were elevated in those exposed to infrasound.

It's not the faslely-accused murderer they executed without trial in 1844 here or the spirits of all those kids who died in that fire the one time; it's that 48" steel ventilation fan whirring away at 17Hz.
