Old creepy houses are a horror cliche, but why? Why do they freak us out? According to new research, it might have something to do with <a href="https://www.sciencefriday.com/segments/infrasound-haunted-house-explanation?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri?" target="_blank" rel="noopener noreferrer">infrasound</a>: a sound that’s below the range of human hearing, potentially emitted by low-rumbling pipes or old boilers more common in older houses.  
Psychologist and pseudoscience researcher Rodney Schmaltz explains his new study, and what role infrasound could play in leading people to feel unsettled in “haunted” places. Then, infrasound researcher Milton Garcés breaks down the infrasound that’s produced by volcanoes and asteroid impacts, and how it serves as a “keep away” signal in nature.
Guests:
Dr. Rodney Schmaltz is a professor of psychology at MacEwan University in Edmonton, Alberta.
Dr. Milton Garcés is a research scientist at the Hawai‘i Institute of Geophysics and Planetology and director of the Infrasound Laboratory at the University of Hawai’i in Honolulu.
