Samenvatting
Thirty human volunteers participated in 75 exposures to short duration impact (less than 10 msec). The tests were conducted to investigate the ability of the subjects to discriminate different pulse durations in the short duration region. Theoretical studies done previously imply that the subjects should only be sensitive to velocity change and not pulse duration below 10 m/sec duration. The tests were conducted on a free-fall facility with the subject in a seated position. The results of these tests and data derived are discussed relative to physical tolerance and injury potential.
