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。

Abstract: The synthesis app roach for noise control p ressor house is p roposed based on the
sound intensity p rincip le, acoustic vibration coup ling theory and sound diagnosis technique. During the
noise control, the main noise sources, the sound transm ission paths and the noise characteristics
p ressor are analyzed by the sound intensity method and vibration acoustic coup ling theory. Furthermore,
the op timal sound level reduction is p redicted 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, p recise measurement can be p rovided and reasonable p rediction can be obtained. A s
the result of this investigation, it is seen that the effectiveness of thismethod is characterized by reduction
