海上油气田生活设施的噪声特征

Noise Characteristics of the Living Facilities in an Offshore Oil and Gas Platform

目的了解海上油气田生活设施的噪声特征,为生活楼噪声控制提供依据。方法对某海上油气田生活设施内外噪声强度和频谱特征进行调查。结果该海上油气田生活设施内外的噪声分别为35.1 dB(A)和73.3 dB(A),生活设施内的倍频带声压级比生活设施外的低。结论该海上油气田生活设施内噪声水平和倍频带声压级均符合0类声环境功能区环境噪声限值要求,生活设施外噪声水平超过4b类声环境功能区环境噪声限值要求。

[Objective]To understand noise characteristics of the living facilities in an offshore oil and gas platform,provide the basis for noise control in the living building.[Methods]The noise levels and noise spectrum of the inside and outside of the living facilities in an offshore oil and gas platform were detected.[Results]The noise levels of the inside and outside of the living facilities were respectively 35.1 dB(A)and 73.3 dB(A).Sound pressure levels of the inside were lower than that of the outside of the living facilities.[Conclusion]The study suggests that the noise level and the sound pressure levels of the inside of the living facilities was lower than the noise environmental quality standard for the category 0 acoustic environment functional area,while the noise level of the outside of the living facilities was higher than the noise environmental quality standard for the category 4b acoustic environment functional area.
