Variability in the design and process variables of the shock tube and its effect on shock wave profile, bTBI injury and behavior in animal models. The compressed gas and number of membranes used affect the incident pressure generated in shock tubes. The geometry of the shock tube, presence or absence of a transition section affect variables of the shockwave profile such as rise time, peak pressure, duration, and impulse. The animal locations inside, near exit and far from exit of the blast tube play a role in the injury severity and behavioral outcomes. P1 and P2 represent the side on blast pressure measurement sensors.
