To reduce environmental noise pollution and to safeguard people’s well-being, it is urgently necessary to move towards sustainable urban development and reconcile demographic and economic growth with the protection and restoration of the environment and the improvement of the quality of human lives. This challenge should be a concern to policymakers, who must issue regulations and define the appropriate actions for noise monitoring and management, and citizens, who must be sensitive to the problem and act accordingly. Starting from an analysis of several crowdsourcing noise data collection tools, this paper focuses on the definition of a methodology for data analysis and mapping. The sound sensing system, indeed, enables mobile devices, such as smartphones and tablets, to become a low-cost data collection for monitoring environmental noise. For this study, the “NoiseCapture” application developed in France by CNRS and IFSTTAR has been utilized. The measurements acquired in 2018 and 2019 at the Fisciano Campus at the University of Salerno were integrated with the kernel density estimation. This is a spatial analysis technique that allows for the elaboration of sound level density maps, defined spatially and temporally. These maps, overlaid on a campus facilities map, can become tools to support the appropriate mitigation actions.

In order to manage noise pollution and reduce its environmental impact and health outcomes, several regulations have been issued in the last few decades, defining acoustic indicators and their thresholds. However, the acoustic environment can be considered a resource, focusing on people’s subjective perception of sounds in accordance with the soundscape approach. The integration of the tools, already applied by the legislation, and the soundscape technique produces a more thorough and comprehensive evaluation of the environmental noise that is necessary for its management. Starting from the best practice of the soundscape in urban planning, this paper presents an application of this approach at the Fisciano campus of the University of Salerno (Italy). The overarching goal is the comparison between the physical parameters, obtained by measuring the sound pressure level, and the psychoacoustic ones, derived by questionnaires given to a group of local experts during a soundwalk. The results will show, for example, some areas characterized by high sound pressure levels and a good perception of the soundscape. As a consequence, the application would seem to have discrepancies between the results of the two methods, but a deeper analysis can reveal further information to the traditional measurements that allow a more accurate knowledge of the acoustic environment.
