Study suggests infrasound causes eerie feelings in old buildings.
A new study suggests that eerie feelings in old buildings may be caused by inaudible infrasound, a low-frequency sound wave below human hearing.
Researchers found exposure to this sound can trigger stress, irritability, and sadness even when people do not consciously detect it, potentially explaining why some people feel uneasy in supposedly haunted places.
