Journal of Atmospheric and Terrestrial Physics, 1971
Abstract We consider atmospheric pressure variations in the period range from a few seconds to a few minutes. These pressure fluctuations arise 1. (a) from local hydrodynamic effects which are estimated; 2. (b) from nonpropagating pressure effects associated, for example, with a jet stream; 3.

The Journal of the Acoustical Society of America, 1978
A trial was made to investigate cardiopulmonary response to infrasound (IFS) in man and dogs whose whole body were exposed to high level (110 dB SPL) of infrasound (8–50 Hz), produced by a powerful speaker system. Experiments on man revealed that heart rate and respiratory frequency decreased by the mean values of 10% and 20% respectively but no ...

Seismometers as infrasound sensors
The Journal of the Acoustical Society of AmericaAn experiment was conducted in West-Central Mississippi in which five explosive charges were detonated. The TNT equivalent sizes of the charges ranged from 0.57 to 10.91 kg (1.25 to 24 lb). Among the arrays of sensors deployed, seismometers were deployed near microphones at distances of 0.5, 2.1, and 8.4 km from the source.
