为探讨潜艇舱室噪声对工效的影响，对１３名被试者进行了实验。结果表明，当舱室噪声由中等强度（７３ｄＢＡ）增至较高水平时（８５～９２ｄＢＡ），信号识别和算题作业均一致出现持续下降，但在更高的噪声水平（９６ｄＢＡ）时，工效的下降趋于稳定。噪声级为８５ｄＢＡ时工效受到明显损害。对两种作业工效的比较表明，在不同的水平下，噪声对具有紧张作业的工效（算题）干扰作用更大。
To investigate the impact of submarine cabin noise on work efficiency, 13 subjects were tested. The results show that when the cabin noise increases from medium intensity (73dBA) to higher level (85 ~ 92dBA), the signal recognition and computational tasks consistently decrease continuously. However, at higher noise level (96dBA), ergonomics Decline tends to be stable. Ergonomics were significantly damaged when the noise level was 85dBA. The comparison of the ergonomics of the two operations shows that under different levels of noise, noise plays a more significant role in ergonomics (computational problems) with intense work.
