Correlation between perceived disturbance and monitored noise in Milan

Noise produces a direct negative influence on the physical and psychological well-being of the exposed population. Surveys addressed to the population allow to evaluate the degree of annoyance produced on the population by different urban noise sources. In this paper, we analyze the results of surveys distributed to people living or working in District 9 of Milan. We have chosen this area because of the presence of permanent noise monitoring stations installed as part of DYNAMAP project. DYNAMAP is a European Life project realized with the aim of developing a dynamic approach to noise mapping, owing to its capability to update environmental noise levels through a direct link with a limited number of noise monitoring sensors, permanently installed in the area. Here, we present the correlation between the population perception to annoying noises (derived from the answers provided to the surveys) and the energetic and statistical acoustic indices (derived from the elaboration of the acoustic data collected by using the DYNAMAP sensors) in order to have a more realistic evaluation of the soundscape in urbanized areas.
