摘要
采用声强离散点法和声振耦合理论对煤气压缩机房噪声进行测量分析,得出主要噪声源、噪声产生原因及噪声传递路径等特征;利用声诊断技术对噪声信号进行预测,得出最佳降噪量;依据分析结果制定了综合治理措施。实施效果表明,测试精确,预测合理,方案措施有效。该治理方法避免了噪声控制的盲目性,更经济合理。
The synthesis approach for noise control of compressor house is proposed based on the sound intensity principle, acoustic vibration coupling theory and sound diagnosis technique. During the noise control, the main noise sources, the sound transmission paths and the noise characteristics of compressor are analyzed by the sound intensity method and vibration-acoustic coupling theory. Furthermore, the optimal sound level reduction is predicted by sound diagnosis technique. And the best noise reduction is obtained. According to the results of analysis, a synthetic control strategy is made. Results show that with this strategy, precise measurement can be provided and reasonable prediction can be obtained. As the result of this investigation, it is seen that the effectiveness of this method is characterized by reduction of acoustic radiation and transmission of sound. This method is of benefit for the noise control.
