The conversation also dives into rumors that some well-known haunted sites may intentionally pump infrasound to enhance activity and mislead ghost hunters. Also: what is the connection between <strong>Bigfoot </strong>and infrasound?</p><p>GEMINI Summary: This episode of "Paranormal Lens" discusses the "ghost frequency," also known as infrasound, specifically the 18.9 Hz frequency (2:00).</p><p> What is Infrasound? Infrasound is a low-frequency sound that humans cannot consciously hear, but our bodies can react to it (3:16). Researchers have suggested that this frequency, when present, can cause feelings of unease, paranoia, and jitteriness, which people might attribute to paranormal activity (3:52).</p><p> Infrasound and Paranormal Activity: The hosts reference a 2003 NBC News article titled "Infrasound linked to spooky events," which discusses a study by UK researchers on the connection between infrasound and odd sensations experienced at allegedly haunted sites (3:05).</p><p> Infrasound in Media: The hosts discuss how horror movies often use infrasound in scary scenes to induce a feeling of fear in the audience before visual or auditory cues (4:32). Ben, one of the hosts, reveals he intentionally used the ghost frequency in their short film, "The Possession Tape," to enhance the unsettling atmosphere (11:41).</p><p> Ethical Concerns of Using Infrasound: The hosts debate the ethics of using infrasound to induce fear. They conclude that it is not unethical in entertainment, such as films, where the audience expects to be spooked (14:42).</p><p> Infrasound in Nature and Other Connections: Bigfoot: Infrasound is believed to be one of Bigfoot's vocalizations, similar to how lions use infrasound in their roars (7:55). Some Bigfoot hunting techniques involve using amplifiers to detect infrasound (8:41).</p><p> Natural Events: Infrasound can be produced by natural events like volcanoes, earthquakes, and storms, as well as by animals and industrial machinery (19:49).</p><p> Bad Driving: The hosts humorously note a random quote in the 2003 article that links infrasound to bad driving, suggesting it might be caused by sounds from cars or radios (5:43).</p><p> Future Applications: The hosts discuss the potential for using infrasound in future paranormal investigations, particularly if they go Bigfoot hunting again (24:03). They also mention an upcoming project that might incorporate it (22:55).</p>
