船舶舱室某些物理因素对人体工效的影响

Effect of Some Shipboard Physical Factors on Human Performance

文章研究了噪声、温度、湿度及照明对人体工效的影响。试验在模拟船舶舱室内进行，共有４种物理因素６种排列组合。受试者为男性青年，健康，听力正常。研究发现，听阈偏移仅由噪声引起，而统计学分析表明，强噪声、低温度、高温及高湿可引起视对比敏感度函数下降。与低水平的噪声、温度及湿度相比，强噪声、高温及高湿复合因素可使视。

The effects of noise,heat,humidity and lighting on human performance were investigated.Six young male volunteers with normal hearing were tested in a simulated ship cabin under 6 combination of 4 physical factors.It was found that the hearing threshold shift was only affected by noise,but the statistical analysis showed a decrease in visual contrast sensitivity function (3.7 cpd) induced by intense noise,low lighting,high temperature and high humidity.In comparison with the combination of low-level noise,temperature and humidity,the auditory and visual reaction time were signification prolonged by the combination of intense noise,high temperature and high humidity.
