The percentage of the population exposed to harmful acoustic pollution levels resulting from vehicular traffic in the Hospital' area of Turin.

This paper presents the methodology and the main results of a study that has as its principal aim, the experimental identification the application and the quantification of the sustainable indicator 'Percentage of the population exposed to acoustic pollution levels' in the 'Hospital' area of Turin. The investigation of this indicator was prompted by the province of Turin's previous categorisation as 'Lead City' in the project 'Towards a support description at local the level--European Community Indicators'. Alongside, the process of experimenting, applying and quantifying the sustainable indicator--and as a logical fit with what was foreseen by the Italian normative regulation on protection against environmental acoustic pollution--the study supplies the base elements to analyse the environmental acoustic climate conditions in an important area of the city and defines the interaction tools that are the environmental indicators for the town council's future Acoustic Restoration Plan (PRA).
