Study About the Effects of Noise on Crew’s Thinking Ability

Abstract

In order to study the effects of noise on the thinking performance of armored vehicle crews, the typical information processing task test is conducted based on the performance indicators of correctness and reaction time. The experimental results show that during the 60-min exposure under noisy condition, the accuracy rate of the subjects did not change significantly compared with the control group, while the reaction time performance and comprehensive performance decreased significantly. The comprehensive performance of subjects decreased with the increase of noise intensity, but the decrease was reduced with the increase of noise intensity. To sum up, noise has a certain impact on crew’s thinking performance, and crew’s performance decreases with the increase of noise intensity. When noise reaches a certain level, it has no significant effect on crew’s performance, indicating that noise has an impact on crew’s thinking ability.
