Experiences in introducing noise management processes: Particular needs require particular solutions

Different Authorities are introducing the Noise Management concept as an integrated process that helps to develop activities on assessment, prevention, correction, public information and participation. On that sense they try to involve on this process to spatial and noise source managers. This paper refers to experiences leaded by different authorities, and analyses three subjects. Firstly, it shows problems and practices when different departments and authorities are required to take part in the process. Secondly, it exposes the aspects to be taken into account in each case to adapt the process and the system that supports it. Surely, there will be some particularities on the approach done by authorities according to their needs and priorities, to the situation to be managed, to the administrative structure, or to the availability and quality of input data. The noise management process should adapt to each situation. This will lead into particularities on the scope of the process, on the actors involved, on the system that could support it, and on the technical methodology applied. Finally, the paper analyses two specific Noise Mapping implementations, applying the Good Practice Guide published by WG-AEN. It assesses and compares the input data used in each case and the methodologies applied to answer to the END. The paper is based on the experience of Labein introducing Noise Management System in different Spanish authorities and, in particular, on two projects done for the Environment Departments of Diputación Foral de Bizkaia Provincial Authority) and Gobierno Vasco (Regional Authority).
