摘要： 为工业企业听力保护计划制定、人机工程学设计及劳动者烦恼度缓解等提供客观的生理依据，分析了生产性噪声对工作人员脑认知的影响.采集自愿者在90dB(A)的稳态机械性噪声刺激以及安静状态下的脑电信号，建立事件相关脑电位ERP中N1(N100)波的幅值脑地形图及P2(P200)波幅值的脑地形图，对ERP信号进行时频分析.结果表明噪声刺激与静音状态相比，ERP在N1波的幅值明显减少，而在P2波幅值变化呈相反趋势明显增加.噪声刺激下被试额区导联的N1幅值显著减小，P2幅值显著增加，表明高声压级生产性噪声导致被试烦躁、注意力分散，并干扰了认知能力.

Abstract: The influence on brain of subjects from industrial noise is analyzed to provide objective physiological basis for the hearing protection planning， annoyance ease and ergonomic design in the industrial enterprises. EEG signals are recorded using 32-electrode-device from 10 college students under the condition of industrial noise and quiet. The signal data was preprocessed by SCAN software， including removing eye electricity， wake， filtering， segmented merger etc. The ERP for 500ms were analyzed and the N1 (N100) and P2 (P200) amplitude value of brain topographic map were mapped. The analysis results of ERP shows that amplitude of N1 decreased significantly while the amplitude of P2 raised distinctly on the contrary. High SPL industrial noise can lead to attention distraction， annoyance， emotional tension， and interference of cognitive ability.

Key words: industry noise, EEG, ERP, N100, P200, cognition, man-machine engineering, brain topographic map
