WBV vs Seismometer+

Whole-body vibration refers to the vibration transmitted to the human body whilst supported by a vibrating surface. The most common exposure occurs through the buttocks when seated in a vehicle. Long term exposure to high amplitude whole-body vibration is strongly associated with the development of back pain and other adverse health effects. The Whole Body Vibration application (WBV) utilizes the accelerometer within an iPod or iPhone to provide an estimate of vibration amplitude consistent with the methods described in ISO2631.1. Frequency weighted r.m.s and VDV values are presented graphically with reference to the health guidance caution zone for exposures of varying durations. Summary data and acceleration time series are available to be emailed or downloaded. The application is intended for use within occupational contexts to provide a simple screening or monitoring tool for use by workplace safety and health staff. It is suitable for use to estimate whole-body vibration amplitude of seated operators of all vehicles, plant or equipment. Use is straight forward. After entering trial information, sampling is commenced with a tap and the device placed on the operator’s seat during a period of normal operation. At the completion of the period, sampling is ended with a tap and the results calculated and made available for viewing and emailing. The application has been developed by the consultants at the Byte Works under direction of Robin Burgess-Limerick, Professor of Human Factors in the Minerals Industry Safety and Health Centre at The University of Queensland, AUSTRALIA. The project was funded by the NSW Coal Services Health and Safety Trust. WBV supports the use of GPS, optionally in the foreground and always when background processing is used. The location information is included in the raw data file, which is available using the export features. Continued use of GPS running in the background (or foreground) can dramatically decrease battery life. You can turn GPS on or off using the WBV preferences, available from the Settings app.
