Whole body vibration exposure calculation from Axivity accelerometers according to ISO2631 standard

WBV Calculator

WBV Calculator is a tool to calculate Whole body vibration exposure from small wearable accelerometers according to ISO 2631 standard. We can use this tool to measure whole body vibration exposure using Axivity AX3 or Axivity AX6. Theoretically any other triaxial accelerometer with sufficient range and high enough sampling frequency can be used with minor changes to data file loading part of the software.

Installation:

• Download the tool from Github releases and double click the file WBV_Calculator_SelfExtract_XXX.exe to extract the executable file to a folder of your choice.
• Install Matlab Runtime 2020b for Windows 64bit from this link
• Then start the executable file WBV_Calculator_XXX.exe to start the software.

Presentations and demonstrations:

• Application of low-cost accelerometers for measurement of whole body vibrations - NES 2022, Uppsala
• WBV Calculator demonstration

Pilot study and validation

Information about a validation study regarding feasibility, and accuracy of the tool, see:
