Additionally, these chest wall and body hair vibrations have also been shown to occur in the infrasonic
range (Mohr, Cole, Guild, & Vongierke, 1965; Schust, 2004).
The tip of the trunk contains two kinds pressure-sensitive nerve endings Meissner's corpuscles that detect infrasonic
vibrations, and Pacinian corpuscles that respond to vibrations with slightly higher frequencies.
The book begins with an introduction to techniques behind the statistical design of experiments, then covers areas such as vibration isolation for sensitive instruments and machines, piezoelectric actuation for nanometer motion control, design of a viscosimeter, and infrasonic
and ultrasonic microphones.
Some additional topics explored are family structure, bonding, infrasonic
communication, mating, emotions, intelligence and evolution.
Last year Mahler became the first horse to win this after contesting a Classic since Infrasonic
calls can travel effectively for miles though air, land and water to the animal's family members.
My award for the most unique item at the show goes to Eminent Technology for the TRW 17 Infrasonic
technology this device uses a special sensing circuit that can detect inaudible sound waves and, if activated, sets off a 110 decibel alarm
Elephants have very deep voices, mostly infrasonic
, with only some of their sound vibrations in the range of human hearing.
Besides analyzing video footage turned in from amateur astronomers and space flight enthusiasts, investigators are looking at defense radar records, telescope images and infrasonic
data from the National Oceanic and Atmospheric Administration.
BH: Satie's ambient experiments caused some bodily effect, even if unconscious; he would have been interested in "brown sound," an infrasonic
frequency first used by the French police on '68 rioters, which makes people shit themselves.
Preliminary findings with electrostatic fields, ionizing radiation, infrasonic
waves, and meteorological factors are also examined to consider their effects on the brain in relation to apparitional experiences.
