<p>In order to be able to quickly identify rattles and squeaks occurring on vehicles, a vibration generator is used which causes the vehicle to be vibrated at a range of different frequencies (C). By setting up the apparatus so that the frequency range is traversed whilst a vehicle is being caused to vibrate, the frequency at which the noise begins to occur (A) can be noted, the frequency at which the noise stops occurring (B) can be noted and this information can be compared with stored data (E) to identify the source of the noise. <IMAGE></p> |
