A methodology to control noise through footprint analysis is proposed. It involves determining the noise contribution produced by significant sources in their surroundings, such as transport infrastructures (not just aircraft and airport), industrial sites and other technical facilities, or by individual sources throughout their life cycle, including motor vehicles, machinery, equipment and the typical devices to which we are exposed during working or leisure time. The main acoustic parameters must be analysed: measurement and simulation of noise indicators, comparison with the limits imposed by legislation and calculation of any overruns are expected. The paper illustrates the technical issues of the research concerning noise footprint. The aim is to provide scientific and technical support to the implementation of noise abatements and environmental sustainability. The scientific value of the research consists in the study of approaches, tools and opportunities to convert noise descriptors in population and soil units referred to the exposed number of inhabitants, by quantifying the areas where noise limits are not exceeded as well as a kind of compensation to allow sustainable development. Therefore noise footprint is not merely a graphical representation of noise contours on maps. As an example of application of footprint analysis to noise, a pilot project and the study of patented solutions are in progress.

Abstract
A methodology to control noise through footprint analysis is proposed. It involves determining the noise contribution produced by significant sources in their surroundings, such as transport infrastructures (not just aircraft and airport), industrial sites and other technical facilities, or by individual sources throughout their life cycle, including motor vehicles, machinery, equipment and the typical devices to which we are exposed during working or leisure time. The main acoustic parameters must be analysed: measurement and simulation of noise indicators, comparison with the limits imposed by legislation and calculation of any overruns are expected. The paper illustrates the technical issues of the research concerning noise footprint. The aim is to provide scientific and technical support to the implementation of noise abatements and environmental sustainability. The scientific value of the research consists in the study of approaches, tools and opportunities to convert noise descriptors in population and soil units referred to the exposed number of inhabitants, by quantifying the areas where noise limits are not exceeded as well as a kind of compensation to allow sustainable development. Therefore noise footprint is not merely a graphical representation of noise contours on maps. As an example of application of footprint analysis to noise, a pilot project and the study of patented solutions are in progress.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
