The work presents quantitative relations between service-dependent noise dose levels and "unspecific" for the noise influence remote effects basing on the study of the cardiovascular system of 207 members of the deck and engine room crews. The seamen observed had no hearing losses due to noise (according to the ISO standard 1999). The study carried out in the pause between sea-going voyages showed that when the length of the service exceeded 10 years the noise dose increment of 1 dB corresponds to the hypertension frequency increment of 2%. The increase of the dose and the length of the service turns out as a trend towards the diminished mean arterial pulse pressure (AP) and elevated diastolic and mean dynamic AP. By resorting to the correlation-regression analysis the information value of the mean dynamic AP for the noise influence evaluation was shown as well the possibility to determine the safe noise action dose which may not be over 100 dB at the service length under 40 years.
这项工作基于对207名甲板和机舱船员心血管系统的研究，呈现了与服务相关的噪声剂量水平和噪声影响的“非特异性”远程效应之间的定量关系。所观察的海员没有因噪声导致的听力损失（根据ISO标准1999）。在两次出海航行的间隙进行的研究表明，当服务年限超过10年时，噪声剂量每增加1分贝，高血压发病率就增加2%。剂量和服务年限的增加呈现出平均动脉脉搏压（AP）降低以及舒张压和平均动态AP升高的趋势。通过相关回归分析，显示了平均动态AP在评估噪声影响方面的信息价值，以及确定安全噪声作用剂量的可能性，在服务年限低于40年时，该剂量不得超过100分贝。
