Abstract:The LIFE GIOCONDA is an ongoing project that aims to provide an innovative methodology to the authorities for supporting the environment & health policies by involving the young people in the decision-making processes. The project suggests a web platform able to relate air and noise pollution data in the schools with the students' pollution awareness. GIOCONDA aims to enhance the awareness of students, teachers and local administrations on the noise issues in schools, presenting suitable tools to improve the public participative processes. This paper presents a new method that has been developed within the Project. It aims to evaluate the acoustic performances of a classroom and to suggest the use of a global indicator based on a group of acoustic parameters compared with their limit values. Whit the new method the comparison between different classrooms or different schools becomes possible, together with a homogeneous evaluation of the priority for planning noise mitigation actions. Several noise measurement campaigns have been performed to characterize the students' exposure in eight Italian schools. The results are useful to describe the acoustic performances of classrooms.

In almost all urban contexts and in many extra-urban conurbations, where road traffic is the main noise pollution source, the use of barriers is not allowed. In these cases, low-noise road surfaces are the most used mitigation action together with traffic flow reduction. Selecting the optimal surface is only the first problem that the public administration has to face. In the second place, it has to consider the issue of assessing the efficacy of the mitigation action. The purpose of the LEOPOLDO project was to improve the knowledge in the design and the characterization of low-noise road surfaces, producing guidelines helpful to the public administrations. Several experimental road surfaces were tested. Moreover, several measurement methods were implemented aiming to select those that are suitable for a correct assessment of the pavement performances laid as mitigation planning. In this paper, the experience gained in the LEOPOLDO project will be described, focusing on both the measurement methods adopted to assess the performance
