Our guest is ghost hunter David Rountree who will talk about his new book “ Paranormal Technology: Understanding the Science of Ghost Hunting.” David is the Director of S.P.I.R.I.T.(Scientific Paranormal Investigative Research Information and Technology), Co-Founder of New Jersey Paranormal Investigative Coalition, a member of the Rhine Research Center, life member of the New Jersey Ghost Hunters Society, member of the International Paranormal Investigators, and a member of the International Paranormal Research Association. David participated in his first investigation of a haunted house at age 17 and later received his Masters Degree in Electronic Engineering in Digital Signal Processing and is currently working on his doctorate in physics. From 1977 until 2001, he performed many investigations in the area in and around Gainesville, Florida, as a member of a small, highly specialized research team. During this time David experimented with both scientific as well as metaphysical techniques in his study of unexplained occurrences he and his small team encountered. Due to several encounters of a very negative nature from 1985-87, he made the decision to concentrate on the scientific research concerning the phenomena, and not the metaphysical aspects of the events. His primary focus since 1998 has been EVP research, employing his background of audio engineering and psychoacoustics. In 2005 David successfully linked electromagnetic fields as the primary source of EVPs. He continues to gather data to attempt to locate the source of the electromagnetic fields that cause both EVP and paranormal phenomena.
