Infrasound, sometimes referred ... In the wake of this serendipitous discovery, the researchers soon got to work preparing further infrasonic tests in the laboratories.
Infrasound sensitive fibers have very high rates of spontaneous discharge, with a mean of 115imp/s, which is much higher than the spontaneous discharge of other auditory fibers. [17] Recordings show that discharge rates do not increase in response to infrasound stimuli but are modulated at levels comparable to the behavioral thresholds. [17]
Acoustics is the interdisciplinary science that deals with the study of mechanical waves in gasses, liquids, and solids including vibration, sound, ultrasound, and infrasound. A scientist who works in the field of acoustics is an acoustician , while someone working in the field of acoustical engineering may be called an acoustical engineer . [ 3 ]
Much work in acoustics requires a good grounding in Mathematics and science. Many acoustic scientists work in research and development. Many acoustic scientists work in research and development. Some conduct basic research to advance our knowledge of the perception (e.g. hearing , psychoacoustics or neurophysiology ) of speech , music and noise .
Infrasound works by having multiple stations that use microbarometers to listen for infrasonic waves caused by explosions, volcanoes or other natural occurring events. [10] As with other detection methods, infrasound was developed during the Cold War. [11] These stations were designed to detect explosions with forces as low as 1 kiloton.

For army infrasound applications, the target frequency range was in the 1–20 Hz band. [3] Infrasound has the ability to reach distances of 100–500 km. There are natural sources of infrasound emissions, such as avalanches, tornados, volcanoes, earthquakes and man-made sources of infrasound, such as aircraft engines, helicopters, artillery ...
