Hardware and Software means


		Each project needs to take into consideration the standard in use to define the acoustical constraints. Modelling means allow the simulation of situations and the forecasting of effects of acoustical devices on the project’s noise impact. They make it possible to define a strategy to reduce noise in the environment.
