Field Measurements of Blast Overpressure in the Context of Ballistic Helmet Wear: FY23 Biomedical Sciences and Technologies Technical Investment Program
Abstract
We conducted a limited-scope study on helmet wear in the context of blast exposure at a military training range for urban combat and breaching. Two participants were exposed, in accordance with range safety protocols, to n = 58 low-level blasts while observing routine training from an overhead catwalk. Data were collected as part of a training protocol assessment for process improvement and so were IRB-exempt; regardless, both participants were informed of the risks and agreed to participate. We recorded acoustic pressures simultaneously from inside and outside of a combat helmet during a blast training exercise using a pair of specialized high-amplitude microphones. Paired blasts were assessed by t-test and t with a power series model to compare the pressures inside versus outside of the helmet.
