Sound is essentially vibration in air, so the topic is familiar to us. From a noise control perspective, it's critical to understand how it is generated and propagated.

​

Vibration in structures, the ground and from machinery may effect humans and it's usually with that in mind that it causes concern.

​

Ground borne vibration from construction, transportation etc may cause cosmetic or structural damage to buildings or causes disturbance to occupants of the buildings. It may also cause re-radiated noise in buildings.

​

Occupational vibration may cause damage or task impairment to people at work, typically from hand-arm vibration (power tools etc) or whole-body (vehicles, platforms etc) vibration.
