The drivers of long distance transport trucks exposed to infrasound vibration (about 115dBA). We studied the effects of infrasound with a questionnaire survey of long distance transport trucks. The questions dealt with general fatigue, yawning, sleepiness, vertigo, tinnitus, headache, sensation of being stifled, hearing impairment, abdominal symptoms and hypertension.We analyzed statistically the incidence of each symptom in relation to exposure to infrasound, the duration of work, the hours of driving and the hours of rest.The results were not statistical by significant. Exposure to about 115dBA of infrasound has no effect on humans.
