噪声是电力生产系统的主要职业危害之一。据调查研究表明，噪声对人体最主要的危害是对听觉系统的损伤，而对心血管的危害也早有报道［１，２］。为了解噪声对电力生产工人听力及心血管系统的危害程度，现采用横断面调查方法对本公司热电厂生产系统的噪声强度及对工人的健康影?
Noise is one of the major occupational hazards of power production systems. According to the investigation and research, the main harm of noise to the human body is the damage to the auditory system, and the damage to the cardiovascular system has long been reported [1,2]. In order to understand the degree of noise damage to the hearing and cardiovascular system of power producers, the cross-sectional survey method is used to measure the noise intensity and the health effects on workers of the Company’s thermal power plant production system.
