An Analysis of Catcher's Mask Performance to Attenuate Head Accelerations
… attenuate head accelerations upon impact with a baseball, and to compare these head accelerations to established injury thresholds for concussions. Testing involved using a pneumatic cannon to shoot baseballs at an instrumented (3-2-2-2 accelerometer array) Hybrid III headform (a 50th percentile …

Vibrational Characteristics of Dummy Headforms
… is especially likely to occur in short-duration impacts with a wider frequency spectrum. The same impact on two headforms that perform similarly in blunt impacts can be much different in shorter-duration projectile impacts due to the vibrational responses. The research presented in this thesis …
