为了探索噪声对人体生理影响的定量关系,分析了噪声的来源和对人体的危害.根据人体的安全生理特征,选取合适的人体生理响应指标.基于受限空间噪声环境模拟试验平台,物理模拟可调控的受限空间噪声环境,开展受限空间噪声对人体生理影响规律的探索性试验;利用噪声影响试验结果构建多元线性回归预测模型,对人体生理响应指标与噪声环境之间的关系进行相关定量分析.试验结果表明噪声对人体的血压、心率、呼吸率的影响程度都比较大,且对心率和呼吸率的影响更具有规律性,确定相关的影响程度的预测模型,为改善恶劣作业环境和制定相关职业健康行业标准提供了科学依据.

In order to study the harm that the noise has done to human being＇ s physiology, this paper analyzes the sources of the noise and what harm it has done to human being. In light of the features of human being＇ s secure physiology, this paper selects the appropriate physiology response index of human being. Based on the simulated experimental platform of the confined space＇ s noise environment, and the simulated physics and the controllable noise environment in the confined space, this paper also makes the exploratory experiment to discuss the laws that the confined space＇ s noise influences over human being＇ s physiology. In addition, it uses the experimental results mentioned above to build the prediction model of multiple linear regression and quantitatively analyze the relation between the physiology response index of human being and the noise environment. Results show that the noise has a great influence over human being＇ s blood pressue and heart rate. Furthermore , it has a regulatory impact over people＇ s heart rate and respiratory rate. The prediction model that defines the degrees of relevant influence has provided scientific grounds for improving the poor working environment and formulating the industcy standards of occupational health.
