The Haunted Room Experiment: Infrasound, Ghosts, and the Power of Suggestion
Aug 11, 2026 · 31m
Summary
Host Tara Perrault explores the psychology behind haunted experiences, examining Vic Tandy’s discovery of infrasound and Michael Persinger’s “God Helmet” experiments. The episode details Chris French’s “Haunt Project,” which found that environmental stimuli like infrasound did not cause paranormal sensations; instead, suggestibility and prior expectations drove the reports. Ultimately, the episode argues that the brain manufactures these eerie feelings through misattribution of bodily sensations in ambiguous, sensory-deprived environments.
