[0071] Experimental example

[0072] In order to evaluate the sound insulation and noise reduction effects of the sound insulation and noise reduction structures of each embodiment and comparative example, the sound insulation and noise reduction structure was made into a regular hexahedron structure (a sound sensor was placed at the center of the regular hexahedron structure) and placed on the floor. Then, a 500g iron ball was allowed to fall freely from a certain distance of 30cm to the floor. Finally, the maximum noise value recorded by the sound sensor inside the regular hexahedron structure was read. The method for making the sound insulation and noise reduction structure into a regular hexahedron structure is as follows: 6 identical sound insulation and noise reduction structures were bonded to each other as six faces to form a regular hexahedron structure. The method for bonding different sound insulation and noise reduction structures to form a regular hexahedron structure was the same. During bonding, ensure that the first polyvinyl chloride layer in the sound insulation and noise reduction structures of Examples 1-3 and Comparative Examples 2-6 was located outside the regular hexahedron structure. When testing the regular hexahedron structures made of different sound insulation and noise reduction structures, the iron ball landed at the same point, and the regular hexahedron structure was in the same position. During the test, ensure that there was no other noise to avoid interfering with the experimental results. The experimental results are shown in Table 1.
