Norstøy
 
    ...key feature of the model is that it makes precise simulations of how the frequency content (spectrum) of the noise is influenced by weather conditions and geometrical details in surrounding buildings, noise screens or topography. NPRA has recently used Norstøy to produce complete noise maps for all major...
