《噪声与振动控制》杂志的公开发行,是我国环境保护工作的一件大事。它对改进城乡居民、工矿企业的生活环境和工作环境,建立一个安静、健康的环境,改善人民的生活质量,促进四化建设将起重要的作用。 当前噪声和振动对城乡居民的干扰很严重,已成为主要干扰源,在噪声、水、空气的三种污染中成为反应最强烈,要求控制最迫切的一种。但是这种情况是不应该的。以城市噪声为例,城市噪声的主要成分是交通噪声,而交通噪声的能量与每小时经过的车辆数成正比,在我国车辆少,车流量几乎是国外大城市繁忙街道上车流量的十分之一,仅此一端我国大城市的交通噪声就应该低10分贝。此外,汽车发 The public offering of “Noise and Vibration Control” magazine is a major event in our environmental protection work. It will play an important role in improving the living environment and working environment of urban and rural residents, industrial and mining enterprises, establishing a quiet and healthy environment, improving people’s quality of life and promoting the four modernizations. At present, noise and vibration have serious interference with urban and rural residents and have become the main sources of interference. They have become the most responsive and require control of the most pressing of the three types of pollution of noise, water and air. But this is not the case. Taking urban noise as an example, the main component of urban noise is traffic noise. The energy of traffic noise is proportional to the number of passing vehicles per hour. In our country, the number of vehicles is small, and the flow of traffic is almost the same as the flow of traffic on the busy streets of major cities in foreign countries One of the reasons for this is that traffic noise at the big cities in China alone should be as low as 10 decibels. In addition, the car hair
