| Has anyone carried out any infrasound experiments with regard to allegedly haunted sites? Infrasonics refers to the study of ultra low-frequency sounds at the edge of and beyond human hearing. According to this wikipedia entry, infrasound is capable of covering great distances and can get around obstacles with minimal fragmentation of the soundwave. An experiment exploring human reaction to infrasound had a significant number of respondents reporting feelings of anxiety, uneasiness, extreme sorrow, nervous feelings of revulsion or fear, chills down the spine and feelings of pressure on the chest.Infrasound is not consciously perceived, so combined with a little bit of wishful thinking, it may induce people to believe they are experiencing a paranormal event. | |

| According to "German Secret Weapons of the Second World War" by Ian V. Hogg the research team led by Dr Zippermeyer built a prototype of "Sound Cannon" which was tested on animals and humans alike. It proved lethal at short range and extremely painful at 300 yards. However it proved absolute useless in practical terms and much more dangerous for the operating crew than the intended target (airplane crews) and was abandoned. It worked emitting ultra-low frequency sounds generated by a methane bruner in a very sophisticated ignition chamber and relayed by a complicated array of sound mirrors. Also tigers are renown to "purr" before attacking: it is barely audible by human ears but it's an ultra-low frequency sound emitted to disorient and confuse the intended prey. | |

| I found an interesting piece on The Atlantic Paranmal Societies website. - Quote :
- In the 1990's, Coventry University Lecturer Vic Tandy was experiencing paranormal activity while working in his laboratory. These included visions, chills, feelings, etc. As a result of his investigation into this phenomenon, he determined that his "ghost" was actually a faulty motor that was emitting a frequency between 17-19Hz. Once the motor was fixed, the phenomenon stopped. After this discovery, he visited various haunted sights in England and found 2 that had high levels of infrasound. In May, 2003, an experiment with infrasound was conducted at the Purcell Room, London by incorporating 17Hz frequencies intermittently into an orchestral concert. Around 700 people attended the two concerts and left surveys questioning their feelings and emotions throughout the event. Their research netted an over 20 percent increase in heightened emotions, anxiety, and chills with the infrasound than without. Low and behold, the scientific realm has finally discounted ghost.....or has it? Out of all the areas that Mr. Tandy visited, he only found two that had infrasonic activity, not all of them. Also, the infrasonic concert doesn't show that any apparitions were viewed that there were times when people felt things when no infrasound was played and vice versa.
What does this mean to the paranormal investigator? For one, be aware that it's out there. The more you know about what there is to disprove them is more for you to use to prove them. Second, small scale detection is complex. Most infrasound detection is accomplished by arrays up to 30ft in diameter for detecting subatomic nuclear explosions or incoming space debris. All references I can find relating to small scale detection is related to noise pollution and usually mathematically calculated.

| Infrasound is something investigators in the field should keep in mind as a possibility. It would be interesting to see if anyone does any long term studies in the subject. | |
