Scaled-distance vibration estimator presented in imperial units (in/s, ft, lb). The K, b, and n values are site-specific and must be calibrated against measured blast events in the units used here. This is the imperial counterpart to the metric Vibration calculator on this site, which is based on the scaled-distance form in AS2187.2 Appendix J. Brent Buffham © 2024.
