Evidence now exists to support the theory that form and mass both directly affect auditory expression occasioned by vehicular impact against flesh. Throughout experimentation a clear pattern was manifest – aged bodies differed markedly from young, morbidly obese from anorexic; sexual dimorphism was measurable. More data is required to compare differences between bodies projected super-vehicle versus those manipulated sub-vehicle. After controlling for subject flight response, point-of-impact percussion ranged between low C and low E; decibels ranged from 105-125, excluding spontaneous ululation evinced by target subjects who saw it coming.
