Is the sound insulation effect of container houses good?

In recent years, with the rapid development of the construction industry, the popularity of prefabricated houses in China has been very rapid. However, as a rising star, the popularity of container houses has been slightly slow. Although the popularity of container houses is not as high as traditional prefabricated houses, their advantages far outweigh those of prefabricated houses.
Those who have used traditional prefabricated houses must know that their sound insulation effect is not ideal, and downstairs you can hear the sound and footsteps from upstairs. This is mainly because there is only a thin layer of wooden boards between the two floors of the prefabricated house. The resonance effect of wooden boards is significant, and their sealing performance is poor. Of course, the sound insulation effect is relatively poor, which brings great inconvenience to daily work and employee life. The structure of container houses is completely different from traditional prefabricated houses. The first and second floors of the container room belong to different boxes. The floor material of each independent box is steel, cement, and ceramic tiles, with a thickness of more than 20 centimeters. Of course, the sound insulation effect of this structure is much better than that of prefabricated houses.
