Infrasound and Its Effects on the Body and Emotions
Explore the fascinating world of infrasound and its profound impact on human emotions, physical sensations, and its potential link to paranormal phenomena.

Understanding Infrasound
Infrasound refers to sound waves with frequencies below the range of human hearing, typically under 20 Hz. Although inaudible, these low-frequency vibrations can have profound effects on the body and emotions, making them a subject of interest in both scientific and paranormal investigations.
Sources of Infrasound
Infrasound occurs naturally and can also be man-made. Common sources include:
- Natural Phenomena: Thunderstorms, earthquakes, volcanic eruptions, and ocean waves.
- Man-Made Sources: Industrial machinery, fans, engines, and certain musical instruments.
- Environmental Factors: Wind passing through specific structures or landscapes.
Effects of Infrasound on the Body
Studies have shown that exposure to infrasound can cause physical and emotional reactions, including:
- Physiological Effects:
- Nausea
- Headaches
- Fatigue
- Dizziness
- A feeling of pressure in the ears or chest
- Psychological Effects:
- Anxiety
- Unease
- Fear
- Disorientation
Infrasound and Paranormal Activity
Infrasound is frequently linked to reports of paranormal activity due to its ability to induce a sense of unease or fear. For example:
- Visual Distortions: Low-frequency vibrations can affect the eyes, causing blurred vision or optical illusions, which might be interpreted as ghostly apparitions.
- Auditory Phenomena: Vibrations can cause objects to emit noises, leading to unexplained sounds.
- Emotional Impact: Feelings of dread or panic often reported in haunted locations might be influenced by infrasound from environmental or structural sources.
Famous Examples of Infrasound in Paranormal Studies
Here are some notable examples:
- The “Ghost in the Lab” Experiment: A British scientist, Vic Tandy, discovered that a 19 Hz frequency emitted by a fan caused him to feel uneasy and see apparitions. When the fan was turned off, the sensations disappeared.
- Haunted Locations: Many “haunted” sites are found to have natural or structural elements that generate infrasound, such as old pipes, wind tunnels, or nearby seismic activity.
How to Detect Infrasound
Detecting infrasound requires specialized equipment, as it is beyond human hearing. Tools include:
- Infrasound microphones or sensors
- Oscilloscopes to visualize low-frequency waves
- Environmental analysis software
Practical Applications in Paranormal Investigations
Infrasound has practical uses in investigations:
- Ruling Out Infrasound: Identifying sources of infrasound can help debunk claims of paranormal activity by explaining physical and emotional responses.
- Enhancing Evidence Collection: Knowing the impact of infrasound can guide investigators to isolate and understand genuine phenomena from environmental effects.
Conclusion
Infrasound is a powerful, often overlooked element in both science and paranormal investigations. By understanding its effects on the body and emotions, investigators can approach cases with greater insight and clarity. Whether inducing fear, creating illusions, or simply being a fascinating phenomenon, infrasound remains a vital consideration in exploring the unknown.
