Introduction
Vibration is present everywhere in our environment. The two main characteristics of vibration are its frequency and magnitude (strength). Vibration is assigned to general categories based on frequency. Not all experts agree on the exact cut-off points for the categories, so any ranges given can vary from text to text. An approximation of frequency boundaries for each category is shown in Figure 1 (Paschold, in press). With regard to human exposure, the following descriptive categories are used ranging from low to high frequency:
Motion:
Whole-body (WBV) :
Hand-Arm (HAV) :
Sound or noise:
Ultrasound
Keywords:
