For comparison, building impact vibration levels are often noted as a single number quantifying the peak particle velocity (PPV, in in/sec or mm/sec). In order to determine the vibration level which could have occurred at a property, the vibration-inducing equipment must be identified, and the distance between the vibration source and the
