摘要
通过计算机模拟，研究了８名被试在５７、８０、９０、９５、１００ｄＢ（Ａ）五种噪声水平下的跟踪作业工效，作业设置三种难度，其被控对象分别为：一阶环节０．５／Ｓ和０．５／Ｓ（０．２５Ｓ＋１）、二阶环节０．５／Ｓ２，实验前对被试进行１６ＰＦ心理素质测定。结果表ＨＢ：８０ｄＢ（Ａ）噪声环境下三种难度的跟踪工效均优于其它几种噪声水平下的结果，但差异不具有显著意义，操作者性格特点对高难度跟踪作业工效有显著的影响。
Eight subjects participated in this study to
investigate the effects of five noise levels(57,80,90, 95, 100 dB(A))on the performance of
tracking tasks with three kinds of dynamics(First-Or-der system 0.5/S and
0.5/S(0.25S+1),Second-Order system 0.5/S2). Before experiment thesubjects were classified as
introverts and extroverts with 16PF inquiry.The results indicated that thetracking performance
on all three kind tasks under 80 dB(A)noise seemed better than those of theothers,but the main
effect for the noise level was in significant,and the operators’personlity factorexerted an
obvious effect on tracking performance only for the high difficult task.
