300 workers of metalurgical plant exposed to vibrations were divided according to the chief work tool into the three groups: 1) moulder, 2) mould cleaner and 3) ironworker--grinder. The velocity of vibration was measured and the spectrum of vibrations examined. The product of vibration velocity excesses was evaluated within the following three bands of frequency: 16--63 Hz, 125--250 Hz, 500--2000 Hz and the frequency of occurrence of the two main forms of vibration disease, i.e. angioneurosis and osteoarthrosis was calculated. The osteoarthretic form of vibration disease was significantly more frequent when the multiplicity of surpassing the velocity of vibration occurred with low frequencies (moulders), and angioneurotic form was more frequent at high and very high frequencies. It seems, that "the safe limit" of vibration frequency should be transferred to frequencies higher than 500 Hz.
一家冶金厂的300名接触振动的工人，根据其主要工作工具被分为三组：1）铸工，2）模具清理工，3）铁匠——磨工。测量了振动速度并检查了振动频谱。在以下三个频率波段内评估振动速度超标乘积：16 - 63赫兹、125 - 250赫兹、500 - 2000赫兹，并计算了两种主要振动病形式，即血管神经症和骨关节炎的发病频率。当振动速度超标倍数在低频时出现（铸工），骨关节炎形式的振动病明显更常见，而血管神经症形式在高频和极高频时更常见。似乎振动频率的“安全极限”应转移到高于500赫兹的频率。
