Abstract: A study concerning noise generated by an italian factory, located in a country land in the north of Italy, was performed in order to determine the most suitable acoustical control actions. This industry fabricates end products through chemical processes involving lead and acid substances. Scrubbers and bag filters are used for air depuration. A progressive approach based on simulations was applied with the aim to find the filters that had to be fixed in order to reduce noise to levels that comply with the particularly restrictive requests of italian law. The first filters considered for noise control were filters proven to have major acoustic contribution on the basis of the results of the first simulation carried out using only already existing control measures. Subsequent simulations were carried out using the same principles, trying to fix before the filters that generate the greatest noise at receptors. Maps of the sound levels inside and around the plant as well as near the more disturbed houses obtained with this procedure, before and after control actions, are shown.
