APPENDIX G Noise and Vibration Assessment

 · The two primary concerns with construction- induced vibration, the potential to damage a structu re and the potential to interfere with the enjoyment of life, are evaluated against different vibration limits. Human perception to vibration varies with the individual and is a function of physical setting and the type of vibration.

Blasting Vibration

PPV is analogous to a speed limit. In other words, as the blasting vibration excites a particle it moves about its point at rest in three dimensions, not in a straight line.
