This Might Explain Why Old Houses Feel Haunted

That uneasy feeling you get in an old, creaking house might not be anything supernatural at all. According to new research, it could be caused by low-frequency sound waves coming from things like aging pipes, boilers, or ventilation systems. These sounds, known as infrasound, are below the range of human hearing but may still affect how people feel.
In a recent Canadian study, 36 volunteers were asked to listen to either calming instrumental music or tracks designed to feel unsettling, similar to those used in horror films. At times, researchers added infrasound at frequencies of 20 hertz or lower using concealed subwoofers. The participants were unable to consciously detect when these sounds were present.
Even so, the results showed a clear pattern. When exposed to infrasound, participants reported feeling more irritated and described the music as more negative. Researchers also measured increased levels of cortisol, a hormone linked to stress. The findings were published in Frontiers in Behavioral Neuroscience.
Psychologist Rodney Schmaltz, one of the study’s authors, explained that these subtle physical reactions could easily be misinterpreted. People who already believe in ghosts, he said, may take that unexplained discomfort as evidence of something paranormal rather than recognizing it as a physical response to environmental noise.
Infrasound is not limited to old houses. It can also be found near busy roads and industrial equipment. Researchers say more work is needed to understand how long-term exposure to these low-frequency vibrations might affect human health.
