Digital modeling

As in the article [BR 100] for the open environment, a distinction is made for boundary effects – soil effects in particular – between reference and laboratory numerical models (which take into account almost all physical phenomena) and simplified (or engineering) models, which are simpler and quicker to implement.

The aim here is to apply acoustic models (reference or engineering) to urban development projects, using conventional indicators (in fine bands, in third octaves or overall) such as sound pressure level (SPL), equivalent energy level over a period T (L _...
