Vibration - Introduction

Firstly the important features of vibration are the level (measured in terms of the velocity or acceleration) and the frequency at which the vibration occurs; the closer vibration occurs to the natural or resonant frequency of say the building's structural elements (building damage) or a person's liver (motion sickness), the greater the effect will be.

In the following sections 

• Environmental vibration affects buildings (BS.7385) or causes disturbance to occupants of the buildings (BS.6472) 

• Occupational vibration causes damage or task impairment to people at work, replica watches by hand arm vibration (BS.6842) or whole body vibration (BS.6841 and ISO.2631).

• instrumentation - selection of the right tool for the job.

The directory can be consulted for consultants and suppliers of suitable instrumentation.  The content is mixed and is of relevance to the UK and internationally.
