The report describes a method for measuring the resultant acceleration at the center of mass of a human subjects head during a simulated crash. An equation is derived giving the resultant acceleration as a simple function of four accelerations measured at points outside the head. Two experiments are described which show that the equation is valid and yields accurate results under test conditions. It is also shown that the calculation of resultant acceleration is not unduly sensitive to small errors in the center of mass location.
