SETTING UP OF A TECHNICAL ECONOMIC INDEX OF PRIORITY SCALES FOR URBAN NOISE CONTROL

摘要

Correct application of the criteria contained in rules and/or recommendations allows verifying the exposure standards and provides technical directions for actions of protection along acoustically similar areas. Taking into account the compulsory value of the rule and the budget demands, in relation to the complexity of the concerned environmental system (noise sources, physical configuration, exposed people, etc.), an effective implementation of noise control measures can benefit by a procedure for fixing the optimum sequence. This paper we first analyse some priority criteria proposed by some of the authors. A further tool is available using the TEI Technical Economic Index, by the authors, that allows to take into account apart those technical (population, noise levels, etc…) also those economics necessary to setting up un index able to take into account the real cost benefit generated by an intervention of noise control. A validation test is executed applying the aforesaid procedures to data sets acquired throughout an Italian urban territory.
