Study: Infrasound likely a key factor in alleged hauntings

A new study in Frontiers in Behavioral Neuroscience says infrasound below 20 Hz may help explain some alleged hauntings.

Researchers argue that low-frequency noise from pipes, traffic, HVAC systems, and wind turbines can intensify arousal and fear.

That heightened state may lead people to misread ordinary sensations as ghostly experiences.

The paper builds on earlier work linking hauntings claims to environmental factors like magnetic fields, humidity, lighting, and infrasound.
