城市变电站噪声烦恼度评估研究
首发时间:2021-01-14
摘要:在中国,城市变电站的噪声污染变得越来越严重。本文提出了一种城市变电站噪声烦恼度的评估方法。首先,采用语义细分法对城市变电站噪声样本进行主观评价;随后,结合城市变电站噪声的典型特性,采用14个声学指标描述噪声样本,进行客观评价;然后,对主、客观评价结果进行相关分析和回归分析;最后,建立了城市变电站噪声评估的回归模型。实际应用表明,该回归模型能够正确预测城市变电站噪声的主观烦恼度。

Annoyance evaluation of noise emitted by urban substation
Abstract:In China, noise pollution from substations in urban areas is becoming more and more serious. An annoyance evaluation of the noise emitted by urban substations is presented. Firstly, the subjective evaluation is conducted on the noise samples from urban substations via the semantic differential method. Subsequently, according to the typical characteristics of urban substation noise, fourteen acoustical metrics are used to describe the noise samples for objective evaluation. Then, the correlation analysis and regression analysis between the objective and subjective annoyance evaluation of noise emitted by urban substation evaluation results are carried out. Finally, a regression model for urban substation noise evaluation is established. Practical application shows that the regression model can correctly predict the subjective annoyance of urban substation noise.
Keywords: urban substation sound quality subjective and objective evaluation annoyance noise
