本文介绍了在波兰工业和交通运输的不同工作场所进行次声噪声测量的结果。这项研究涉及124种不同类型的机器、用具和交通工具发出的噪音。测量是在典型的工作条件下，参照波兰标准PN-86/N-01338和国际标准ISO7196和ISO9612进行的。根据PN-86/N-01338，在1/1倍频程8-31.5赫兹范围内，发现有5例(4.0%)的声压超过了工作人员健康保护所允许的水平，(B)在观察调度室等中发现了履行基本职能的适当条件--77例(62.1%)；(C)行政、设计办公室等--92例(74.2%)。在所有研究的机器中，有66.9%的机器超过听力阈值。
This paper presents the results of infrasonic noise measurements performed at various workplaces in industry and transportation in Poland. The study concerned noise emitted by 124 different types of machinery, appliances and means of transport. The measurements were made under typical conditions of work and with reference to the Polish Standard PN-86/N–01338 and international standards ISO 7196 and ISO 9612. According to PN–86/N–01338, within 1/1 octave bands 8 – 31.5 Hz, acoustic pressures exceeding the admissible levels for (a) workers' health protection were found in 5 (4.0%) cases, (b) proper conditions for performing basic functions in observational dispatcher cabins etc. – in 77 (62.1%) cases; (c) premises for administration, design offices etc. – in 92 (74.2%) cases. The hearing threshold was exceeded by 66.9% of all the machinery under study.
