Vibration monitoring is used to provide ground/structures vibration emission levels. The results obtained are in the form of peak particle velocity (PPV). The PPV obtained is compared to the allowable emission levels for the particular structures evaluated. |
|
Sound monitoring is also similar to vibration measurements. It measures the maximum noise level at the transducer location. These results are then compared to the recommended levels by the local authority or the environmental noise and vibration emission limits. |
