The min and max were presented because there were only two trials for each impact configuration, so a standard deviation could not be calculated. The bare Hybrid III impacts resulted in an average linear resultant acceleration of 226 ± 18 g for a maxilla impact and 232 ± 14 g for a zygoma impact and serve as an estimate for a bare head impact to the FOCUS. All masks reduced head accelerations during maxilla impacts, however some mask yielded accelerations greater than or equal to the bare headform tests during zygoma impacts. This is likely due to variation in skin thickness between the two headforms at the zygoma location. These data suggest that some infield masks are capable of reducing head accelerations
