摘　　要：目的了解海上油气田应急发电机房噪声特征,为应急发电机房噪声控制提供依据。方法对某海上油气田应急发电机噪声强度和频谱特征进行调查。结果该海上油气田应急发电机房噪声为108.8 dB(A),倍频程中心频率为1000 Hz和2000 Hz时倍频带声压级均最大(均是103.8dB)。结论该海上油气田应急发电机房噪声超过国家标准,应采取措施控制应急发电机房噪声。[Objective] To understand noise characteristics of the Emergency Generator Room in an offshore oil and gas platform, provide the basis for noise control in the Emergency Generator Room. [Methods] The noise levels and noise spectrum of the Emergency Generator Room in an offshore oil and gas platform were detected. [Results] The noise levels of the Emergency Generator Room was 108.8 dB(A). Maximum measureable sound pressure level of frequency weighting characteristics were 1000 Hz and 2000 Hz(103.8 dB). [Conclusion] The study suggests that the noise level of the Emergency Generator Room was higher than the standard, while measures should be taken to control noise in the Emergency Generator Room.
