Accredited, Acclaimed, & Renowned GEOTECTONICS PROFESSOR Says the STRANGE SOUNDS ARE REAL. Analyzed & Explained! Ha!

The effects of artificial infrasound acoustics. A few experiments :

When male volunteers were exposed to simulated industrial infrasound of 5 and 10 Hz and levels of 100 and 135 dB for 15 minutes, feeling of fatigue, apathy, and depression, pressure in the ears, loss of concentration, drowsiness, and vibration of internal organs were reported. In addition, effects were found in the central nervous system, the cardiovascular system, and the respiratory system. Synchronization phenomena were enhanced in the left hemisphere. Visual motor responses to stimuli were prolonged, and the strength of effector response was reduced. Heart rate was increased during the initial minutes of exposure. Depression of the encephalic
hemodynamics with decreased venous flow from the skull cavity and was observed. Heart muscle contraction strength was reduced. Respiration rate was significantly reduced after the first minute of exposure.

A low-frequency noise of ~7 Hz occurring in several office rooms produced symptoms in individuals typical of sick building syndrome, demonstrating that the low-frequency component of ventilation noise can be amplified in tightly sealed rooms. It was proposed that repeated or long-term exposure could be "triggering an allergic-type response."


Twenty healthy males (20 to 30 years old) were exposed to frequencies of 6, 12, and 16 Hz at pressure levels of 95, 110, and 125 dB for 20 minutes in one series of experiments and then for one hour with random exposure of infrasound (125 dB/16 Hz) or low-grade frequency noise (50 dB/50 Hz) on alternate days in a second series of experiments. Infrasound (at all tested frequencies) was observed to increase diastolic blood pressure—the most significant effect was seen with 16 Hz, and the maximum mean increase of 8 mm Hg occurred after 30 minutes—and decrease systolic blood pressure and pulse rate, suggesting that a peripheral vasoconstriction with increased blood pressure was induced with acute infrasound stimulation.
