Prediction Model for Impulsive Noise on Structures

Abstract : A study of impulsive noise propagation and its effect on structures has been performed. Propagation and response measurement were conducted on eleven buildings at three military facilities. Sources included artillery and tank gun firing and explosive ordinance disposal. Propagation measurements demonstrated that the primary path is airborne, not groundborne. Frequency Response Functions were developed for the measured structures, and a general single degree of freedom model for structural velocity response was prepared. A model for Probability of Damage from impulsive noise sources was developed and is presented. That model addresses a wide range of structure types, and provides guidance for impulsive noise criteria in communities.
