一、前言 近几年来参加了一些国际噪声控制学术会议,了解到国际上噪声控制技术动向,本文结合我国噪声控制技术的情况,综合介绍国内外噪声控制技术的发展。 早些年,国际上讲科学技术的发展是三句话:更大、更快、更高——机器愈造愈大,建筑物愈来愈高,交通工具愈来愈快,人类对自然的探索愈来愈高。最近,有些新的变化,又增加了一句话:更好——机器愈造愈好,工作性能优、效率高、不产生污染,更安全,更安静,这就涉及到对噪声的要求。
I. Preface In recent years, I participated in a number of international conferences on noise control and learned about the international trends in noise control technology. In this paper, the development of noise control technology at home and abroad is introduced synthetically based on the situation of noise control technology in our country. In earlier years, the development of science and technology in the world was three sentences: bigger, faster and higher - the bigger the machines, the higher the buildings, the faster and faster means of transport, Exploring higher and higher. Recently, some new changes have been added: “Better” - The better the machine is, the better performance, the higher efficiency, the less pollution, the safer and the quieter. This involves noise requirements.
