Descriptions
As industrial activity expands noise emissions from factories or power plants has become a serious social problem. Once facilities have been constructed effective countermeasures for noise reduction become difficult, due to the arrangement of machines, space and cost factors. It is useful to predict exterior noise emission prior to the construction of facilities for noise assessment purposes and effective investment. This paper presents techniques for the prediction of exterior sound fields with the aid of microcomputers. Examples of calculated results are provided.
