Infrasound and Paranormal Activity
Infrasound, particularly frequencies around 18-19 Hz, has been linked to reported paranormal experiences and sensations of unease. Research has shown that exposure to these low-frequency sounds can induce physiological and psychological effects, including anxiety, chills, and visual distortions[1][2]. In controlled experiments, participants reported more unusual experiences when infrasound was present in music, with 22% describing feelings of uneasiness, sorrow, or fear[1][3].
Scientists suggest that infrasound may explain some alleged hauntings and ghost sightings. The human eyeball's resonant frequency is close to 18 Hz, which can cause visual distortions when stimulated by infrasound[2][3]. This phenomenon may account for reported apparitions in locations with natural or artificial sources of infrasound, such as wind, storms, or mechanical equipment[4][2]. While the connection between infrasound and paranormal experiences remains debated, these findings offer a scientific perspective on some ghostly encounters.
