Abstract

A study case of noise coming from road yard machines: experimental tests and theoretical formulas to evaluate sound impact on people F. ~atania',~.~olombrita~, A. ~ a ~ l i a n o ' , F. ~ocera' ' Energy and Environment Division of D.I.I.M 2 Civil and Environmental Department Engineering Faculty of University of Catania (Italy) Abstract Sound levels emitted by road yard machines are correlated strictly to engine power, to level of power taken up during the different operative conditions, to ground morphologies and features, to maintenance state of machines and to meteo-climatic conditions during working period. If people could carry out a preventive evaluation of sound diffusion around working machines than they could single out the yard zones where the acoustic limits established by Italian environmental laws would be overcame and, consequently, people could prearrange the convenient technics of mitigations to reduce sound impact on environment. To this aim people analysed as study-case the exp
