一、前言 自施行噪声法规以来已有十四年,各种工厂、机械设备、营业所等,通过经营和操作,对噪声的重要性已有所认识,尽管从一开始就采取了防止措施,但随着交通量和工厂的增加,环境噪声不但没有下降,反而逐年增高,受害范围由市中心向效区扩展,则是与噪声源的增加同步进行的,故没有取得进展。 I. Preface It has been fourteen years since the noise regulations were implemented. Various factories, machinery and equipment, business offices and so on have gained an understanding of the importance of noise through their operation and operation. Despite precautionary measures from the very beginning, However, with the increase of traffic volume and factories, the environmental noise not only did not decrease, but increased year by year. The extent of victimization expanded from the downtown area to the effective area, which was in parallel with the increase of noise sources. Therefore, no progress was made.
