摘要：The noise problem has emerged as a global agenda now and has become a great issue to solve in contemporary society. In order to establish various ways to solve the noise problem, the noise map has been advanced to confirm the level of noise. The noise map is the visual expression of figures and distributions of diverse noises that the noise level which has been expressed only in number has now visualized to understand more easily. Under this study, ‘CRTN’, ‘RLS-90’ as the noise prediction method used in a number of countries, as the noise map has been learned and further found out the noise limit of each country and laws on noise as well. By finding out the standard of some countries, it intends to find out the level of emergence of the noise problem globally. Based on this study, it would be feasible to find out the level of noise problem of each area. Furthermore, the comparative study model can be extended to assess and predict trends and changes in sound environment.
