Abstract:
The usual approach to real-time noise mapping consists in implementing a
localized noise monitoring network that continuously collects noise data and
transmits them to a data center where a noise model software runs. The role of
the noise model software is to re-scale some pre-computed partial noise maps
according to the measured data and to sum the new re-scaled partial maps
together, in order to obtain the whole area noise map to be published and
continuously updated on a web site. At the moment the application of real-time
noise map systems is limited to small areas because of the high cost of noise
monitoring stations and long time needed to run and manage the system. A new
approach to real-time noise mapping will be developed in DYNAMAP (DYNamic
Acoustic MAPping), a co-founded project in the framework of LIFE 2013 program.
The main features of this project are to define a statistically-based method
to optimize the choice and the number of monitoring sites, and to automate the
noise mapping process using the information retrieved from a low cost
monitoring network. Preliminary results and a case study, referring to a small
sample of roads of the city of Milan, will be presented.
