Setting up of a technical economic index of priority scales for urban noise control
2005
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 author…
Noise in a hospital area. Measure and evaluation
2005
The territory of Sciacca has been acoustically subdivided into homogeneous areas by the authors. In the present job, our attention is focused on the zones in class I that includes particularly sensitive areas as schools and hospitals. The acoustic climate inside and outside the hospital of Sciacca is carried out. The hospital was built on a hillock. Around the hillock two roads, an urban and a main highway are present, both with high traffic. With a campaign of measures, in proximity of the roads, in the hospital square, in the parking, and finally inside the hospital, the equivalent level and the patients exposure was calculated as Ld, Ln and DNL. Both the impact due to the roads (consider…
