This clinico-audiological study included 983 workers engaged in coal and ore mining exposed to combined effect of occupational noise and vibration. Pathogenetic mechanisms underlying the development of occupational deafness were shown to depend on intensity and duration of the action of these factors. Impedancometry was used to evaluate the functional state of the middle ear and to study protective and adaptive potential of ear muscles. Criteria are proposed for the identification of groups of workers at risk of development of occupational deafness. The relationship between individual features of cerebral hemodynamics and the functional state of the middle ear is established.
这项临床听力学研究纳入了983名从事煤炭和矿石开采、暴露于职业噪声和振动联合作用下的工人。研究表明，职业性耳聋发生的发病机制取决于这些因素作用的强度和持续时间。采用声阻抗测量法评估中耳的功能状态，并研究耳部肌肉的保护和适应潜力。提出了识别有职业性耳聋发病风险的工人群体的标准。确定了脑血流动力学个体特征与中耳功能状态之间的关系。
