简要介绍了褶皱芯材的结构及其隔声原理,并就褶皱芯材的隔声特性实验研究进行了说明,包括实验所用的试件和仪器、测试的内容、条件和实验的方法,并给出了相应的实验数据。对实验的结果进行了分析后,得出若干结论,所得的结论与隔声原理预测的趋势一致。据此提出了一种构造轻质宽带隔声声屏障的新方法 The structure of the corrugated core material and the principle of sound insulation are introduced briefly. The experimental study on the sound insulation properties of the corrugated core material is also described. The test pieces and instruments used in the experiment, the content and conditions of the test and the experimental methods are given The corresponding experimental data. After analyzing the experimental results, a number of conclusions are drawn and the conclusions drawn are consistent with those predicted by the sound insulation principle. Accordingly, a new method for constructing a light-weight broadband acoustic barrier is proposed
