摘　　要：文章从工业环境噪声对人体心率影响的角度,研究噪声对人体负荷影响规律的方法及实现问题,并开发数据处理系统。在研究方法中,依据工业企业噪声现状选择声级、频率范围;采用能够反映微小变化的心率变异(HRV)作为评价指标,获得噪声对人体心脏的影响规律。该方法与系统实现强调影响劳动安全的人体心脏负荷问题,可从工程生理学与心理学双重角度更为全面科学地研究噪声的影响规律。This paper studies the influence law of human body＇ s load and its realization in industrial noise envi- ronment from the aspect of the noise influencing heart rate, and develops a date processing system. This method choose the studied noise level and their frequency coverage, and take the heart rate variability （HRV） as an assess- ment index, because HRV more reflect a tiny change and obtain a exact law of the heart change influenced by noise. This method and it＇ s system realization more emphasizes person＇ s psychological load at influencing labor security. The influence is discussed on the point of engineering psychology and psychology.
