Evaluations about the acoustic insulation of facade for different construction categories, as calculated by means of the prediction model encoded in EN 12354 and after in situ measurements on buildings in the Mediterranean area

In the present work the acoustic insulation of facade is dealt with, starting from the prediction calculations regarding the assessments for case studies, according to EN 12354 procedures, to go on with the comparisons with in situ measurements carried out at accomplished construction. In detail different building types have been analyzed, i. e. structures in reinforced concrete with infill walls, as well as structures in cross laminated timber and structures in bearing wall realized in Sardinia. In the paper the effect of small elements on acoustic insulation is evaluated apart from the comparison of the performance for different construction types.
