Human Exposure to Vibration

From EverybodyWiki Bios & Wiki


Overview[edit]

Humans can be exposed to vibration in a number of ways both positively and negatively. Humans are exposed to vibration through a contact surface that is in a mechanical vibrating state. Human's are generally exposed to many different forms of vibration in their daily lives. This could be a driver's seat, a moving train platform, through a power tool, a training platform, or one of countless other devices. A few books have been written that focus solely on the human exposure to vibration.[1][2]

What is vibration[edit]

Vibration is a mechanical phenomenon whereby oscillations occur about an equilibrium point. If vibrations are undesired, steps can be taken to isolate the vibration from a particular source.

Whole-Body Vibration[edit]

Whole-body vibration is defined generically as the effect of mechanical vibration from a system transmitted to the human body.

Occupational exposures to whole-body vibrations for long durations can lead to musculoskeletal problems of many kinds. Problems of the neck and lower back in particular can be common for operators of heavy equipment including construction, forestry, agriculture, and trucking. Other occupations where whole-body vibrations may be present include operators of aircraft, workers on-board sea vessels, drivers of public transportation including trains and buses among others.

Factors that affect the occupational exposure to whole-body vibration include the frequency of vibrations, the magnitude of vibrations, the daily exposure to vibrations, the standing or seating posture of the operator, the direction of the vibration, and how tightly coupled the human is to the source of the vibration. Exposure limits and estimates have been characterized in the ISO 2631-1[3] for whole-body vibration

Vibration Training: Whole-body vibrations are commonly thought of as having negative effects on humans, however, in certain circumstances they can be beneficial as vibration training platforms have been gaining popularity. These platforms use mechanical vibrations in a positive way to boost outcomes during workout, training or therapy.[4]

Hand-Arm Vibration[edit]

Hand-arm vibration specifically relates to the vibration transmitted to the hand, wrist and elbow caused by power tools, power washers, and construction tools. Exposures to hand-arm vibration over many years can lead to 'white-finger' with symptoms including tingling, numbness and loss of feeling and control.[5] Exposures and limits have been estimated in the ISO 5349-1[6] for hand-transmitted vibration.

Measurement of Human Exposure to Vibration[edit]

Measurements need to be taken in order to estimate the amount of vibration exposure to the human body. These measurements are commonly taken with accelerometers that measure the accelerations on the human body or at the vibration source or surface. Measurements need to take into consideration the coordinate system of the body and direction of vibration to be measured.[7] Measurement techniques for estimating exposures to whole body vibrations[8] and hand-arm vibration[9] have been developed in International Standards.
