In the railway case, we shall calculate the noise level in a similar way. For airports, we shall use the next equation
where Leq(300m) is the noise level at 300m from the airport.
This model performs satisfactorily for simple sound propagations with no ground interaction or attachment. The application will not consider sound reflections in the ground surface.
