Since the 90s, quiet areas have commonly been considered as places to be acoustically preserved or where acoustic interventions should be implemented to reduce noise levels. With the enforcement of the Environmental Noise Directive in 2002, a formal definition of a `quiet area in agglomeration’ and a `quiet area in open country’ was established. However, many Member States complained about the absence of guidelines regarding the identification and management of quiet areas. The LIFE QUiet Areas Definition and Management in Action Plans (QUADMAP) project started in 2011 to contribute to the Directive’s incomplete requirements for quiet areas. The project’s main result was the introduction of a exible methodology for the selection, analysis and management of quiet areas in agglomeration in which both acoustic and nonacoustic parameters were evaluated. This paper illustrates each phase of the methodology. Moreover, additional analyses are reported that verify the benefits of the proposed complementary selection criteria
(`relative quiet urban areas’ identification criteria and `homogeneous urban areas’ subdivision criteria), detailed methods for defining the measurement periods and the acoustic and nonacoustic parameters to be considered as the most significant. Finally, results from the application of the QUADMAP methodology in 10 pilot areas in Italy, Spain and the Netherlands are presented.
