Study: Infrasound likely a key factor in alleged hauntings

Recent research found that participants exposed to infrasound reported increased irritation, unease, and elevated stress levels regardless of other conditions. While infrasound appears to be one contributing factor rather than the sole cause of hauntings, researchers suggest that low-frequency sound from sources like rumbling pipes in older buildings may amplify supernatural perceptions when people already expect something spooky to occur.
