A new study suggests that infrasound below 20 Hz may be responsible for alleged haunting experiences by raising cortisol levels and increasing irritability. The research indicates that low-frequency sounds from sources like rumbling pipes rather than supernatural forces create spooky sensations. This provides a scientific explanation for phenomena traditionally attributed to ghosts or spirits.
Background
Infrasound refers to sound waves with frequencies below the lower limit of human audibility, which can still affect the human body despite being inaudible. Previous research has suggested connections between infrasound and various physiological and psychological effects.
