ABSTRACT
Mechanical vibration arises from a wide variety of processes and operations performed in industry, mining and construction, forestry and agriculture. and public utilities. Whole-body vibration occurs when the human body is supported on a surface which is vibrating, e.g. in all forms of transport and when working near some industrial machinery. Hand-transmitted vibration occurs when the vibration enters the body through the hands, e.g. in various work processes where rotating or percussive power tools or vibrating workpieces are held by the hands or fingers.
