Building a new road means for the country a socioeconomic growth indeed but, in the other hand, could produce negative impact on environment crossed because of noise emissions coming from motor vehicles running.On this ground an applied research has been carried out both to forecast and to control future acoustic negative effects that could be originate by provincial road “S.P. Misterbianco-Nicolosi” already in last stage of plane. Research has been carried out not only to evaluate any eventual disturbs on the people living in the borders of road but as well as to verify the respect for current Italian regulations about noise pollution. Campaigns of measurement of Leq(A) “ante operam” have been done to validate the calculation codes utilized for such an outdoor environment full of anthropic and natural obstacles to noise diffusion. Therefore paper wants to show: results of campaigns of acoustical measurements; techniques and models of sound diffusion used for forecasting of noise “post operam”; comparison of results of forecast with that ones Leq(A) limits of reference to Italian noise regulations; protections works designed to mitigate Leq(A) one higher than that permitted by regulations.
