Free Whole Body Vibration (WBV) Exposure Calculator

This calculator helps you determine your exposure to whole-body vibration and provides recommendations to ensure you are within safe limits. Please enter the details below:

Vibration Magnitude (X-axis, awx):

Enter the vibration level measured in the x-direction.

Vibration Magnitude (Y-axis, awy):

Enter the vibration level measured in the y-direction.

Vibration Magnitude (Z-axis, awz):

Enter the vibration level measured in the z-direction.

Duration of Exposure (hours):

Enter the number of hours you are exposed to vibration during a workday.

Frequency Weighting:

Enter the frequency weighting factor (use ‘1’ if unsure).

Work Schedule (hours/day):

Enter the number of hours you work in a day.

Work Schedule (days/week):

Enter the number of days you work in a week.

Vibration Reduction Controls:

List any vibration reduction controls you use, if any.

Output	Value	Explanation
Total Vibration Exposure (A(8))		The amount of vibration exposure normalized to an 8-hour workday.
Vibration Dose Value (VDV)		The overall exposure level that takes into account both the intensity and duration of vibration.
Exposure Points		A score indicating your total exposure. Helps determine if it is within safe limits, needs action, or is hazardous.
Recommendations		Suggestions for reducing your exposure based on the results.
