“…With prolonged exposure to WBV, the sensory information received from the somatosensory, vestibular, and/or visual systems could lead to postural instability, contributing to an increased risk of fall during egress of the vehicle. While previous research has been instrumental in determining the casual relationship of WBV and postural stability in simulated laboratory environments (uni-axial vibration) (Futatsuka et al, 1998;Martin et al, 1980;Cohen, 1979;Cornelius, 1994;Couch, 1981;Peli et al, 2003;Roll et al, 1980); the lack of available real-time vibration exposure (tri-axial) in LHF truck drivers, leaves a theoretical void in the literature.…”

Falls from non-moving vehicles constitute a significant portion of fall related fatal occupational injuries, with a yearly average of 48.7 fatal falls, from 1992 to 2002. Whole-body vibration (WBV) has been thought to be a contributing factor to loss of balance, more specifically, falls while descending from a vehicle. The current research employed a "real-time" actual trucking environment, rather than vibration platforms in laboratories, as is typically the case. Nine (9) full-time, long haul truck drivers' drove over 3000 miles in total, while participating in this study. The protocol required postural stability testing prior to, and immediately following, each of three driving sessions of 2.5 hours during a single shift. Results indicate significant changes in postural stability as a result of exposure to extended durations of WBV. The results also showed an increase of sway (cm) at each of the post-test measures compared to the pre-test, and an overall increase over the 8.5 hour shift, suggesting a time dependent increase over the course of the driving shift.

A field study of exposure to whole-body vibration due to agricultural machines in a full-time rice farmer over one year: Hiroji TSUJIMURA, et al. Division of Occupational and Environmental Health, Department of Social Medicine, Shiga University of Medical Science-Objectives: The aims of this study were to clarify in detail the levels of whole-body vibration (WBV) exposure from a variety of agricultural machines in a rice farmer over one year, and to evaluate the daily level of exposure compared with European and Japanese threshold limits. Methods: The subject was a full-time, male rice farmer. We measured vibration accelerations on the seat pan and at the seat base of four tractors with various implements attached, one rice-planting machine, two combine harvesters, produced by the same manufacturer, and one truck used for transportation of agricultural machines. The position and velocity of the machines were recorded in parallel with WBV measurements. In addition, during the year starting in April 2010, the subject completed a questionnaire regarding his work (date, place, content, hours worked, machines used). We calculated the daily exposure to WBV, A(8), on all the days on which the subject used the agricultural machines. Results: The WBV magnitude in farm fields was relatively high during tasks with high velocity and heavy mechanical load on the machine, and had no dominant axis. The subject worked for 159 days using the agricultural machines during the year, and the proportion of days on which A(8) values exceeded the thresholds was 90% for the Japan occupational exposure limit and 24% for the EU exposure action value. Conclusions: Our findings emphasize the need for rice farmers to have health management strategies suited to the farming seasons and measures to reduce WBV exposure during each farm task.

“…The researches indicated that the reaction time in psychomotor efficiency tests becomes extended by 30-40% at infrasound levels of 115-120 dB. Vehicle drivers exposed to simulated infrasound at levels of 100-135 dB for 15 minutes reported feelings of fatigue, apathy, depression, vibrations of internal organs, loss of concentration, and pressure in the ears [18][19][20][21][22][23][24][25].…”

Introduction and objectives. Although exposure to audible noise has been examined in many publications, the sources of infrasound in agriculture have not been fully examined and presented. The study presents the assessment of exposure to infrasound from many sources at workplaces in agriculture with examples of possible ergonomic and health consequences caused by such exposure. Materials and method. Workers'-perceived infrasonic noise levels were examined for 118 examples of moving and stationary agricultural machines (modern and old cab-type tractors, old tractors without cabins, small tractors, grinders, chargers, forage mixers, grain cleaners, conveyors, bark sorters and combine-harvesters). Measurements of infrasound were taken with the use of class 1 instruments (digital sound analyzer DSA-50 digital and acoustic calibrator). Noise level measurements were performed in accordance with PN-Z-01338:2010, PN-EN ISO 9612:2011 and ISO 9612:2009. Results and conclusions. The most intense sources of infrasound in the study were modern and old large size types agricultural machinery (tractors, chargers and combined-harvesters, and stationary forage mixers with ventilation). The G-weighted infrasound levels were significant and at many analyzed workplaces stayed within or exceeded the occupational exposure limit (L G eq, 8h = 102 dB) when the duration of exposure is longer than 22 min./8-hours working day (most noisy -modern cab-type tractors), 46 min./8 hours working day (most noisy -old type cab-tractors), 73 min./8 hours working day (most noisy -old tractors without cabins), 86 min./8-hours working day (most noisy -combine-harvesters) and 156 min./8 hours working day (most noisy -stationary forage mixers with ventilation). All measured machines generated infrasonic noise exceeded the value L G eq, Te = 86 dB (occupational exposure limit for workplaces requiring maintained mental concentration). A very important harmful factor is infrasound exposure for pregnant women and adolescents at workplaces in agriculture. Very valuable work can be technical limiting exposure to infrasound from new and used agricultural machinery. The technical limitation of infrasound caused by both old and new agricultural machinery can be invaluable from the work point of view.
