Every day, much time and effort is spent on measuring vibration levels in factories vehicles, buildings, and on other structures and machines—even products as diverse as computer hard drives and spacecraft as they are being designed, developed, and tested. Thousands of engineers, technicians, consultants, and machine designers have become expert when it comes to measuring how physical objects are affected by vibration. Yet an astonishingly small percentage of this expertise is focused on how vibration in the workplace causes serious injury in humans—injuries that could have been prevented with the right amount of knowledge and the application of a few simple guidelines. When assessing workplace noise and vibration risks the following factors must be considered: Level of noise or magnitude of vibration; duration of exposure (taking into account any overtime) and the range of sources for these exposures; type of noise (e.g. frequency, continuous, high levels of short duration).
