前言随着现代工业、交通运输、航天航空工业的发展,噪声污染在世界各国有显著增加的趋势。如果长期置于噪声环境中,不仅会加速建筑、机器结构的老化和损坏、影响设备和仪器的使用精度和寿命;而且还会使人疲倦、耳聋,甚至危及人的生命。因此噪声控制已成为世界各国科技工作者的重要研究课题。通过模拟部分工业化生产过程,从各类材料研究,组成入手,本项目将研究和生产出一种新型的吸声/隔声产品,
Preface With the development of modern industry, transportation, aerospace industry, noise pollution has a marked increase in all countries in the world. If placed in a noisy environment for a long time, it will not only accelerate the aging and damage to the structure of the building, the structure of the machine, but also affect the accuracy and longevity of the equipment and instruments. Moreover, it will also make people tired, deaf and even endanger human life. Therefore, noise control has become an important research topic for scientists and technicians all over the world. By simulating part of the industrialized production process and starting with the research and composition of all kinds of materials, this project will research and produce a new type of sound absorption / sound insulation products,
