Item Acoustic management of natural parks: Experience in Armañon Park(2015) Aspuru, Itziar; Garcia, Igone; Gutierrez, Laura; Santander, Alvaro; Fernández, Pilar; Madariaga, Iosu; Uribe, Maria; CALIDAD Y CONFORT AMBIENTAL; ADAPTACIÓN AL CAMBIO CLIMÁTICO; Tecnalia Research & InnovationNatural Parks are ecosystems of high value and meet functions of biodiversity conservation, in terms of species and also their soundscape. This paper presents the experience carried out in Armañon Park to integrate variables of noise pollution in the park management tools. The work has two objectives: to prevent biodiversity loss associated with noise interfering natural auditory signals and to enhance the presence of natural sounds as an element of interest to visit the Natural Park. It takes into account not only the noise from outside the park, by consulting noise maps from traditional sources (road traffic, mainly), but it is specially based on the assessment of the noise associated with the uses and activities developed inside the park. The experience carried out in Armañón Park addresses the issue from the two necessary perspectives: identification of areas under preservation against noise pollution and analysis of the acoustic impact on those areas caused by uses and activities in the park. There is a legal framework in the Spanish legislation to define acoustic protection areas (reserve of natural sounds), areas whose sounds are considered subject to preservation for its unique value. The ultimate goal of the project presented in the paper is to have scientifically justified tools to condition the acoustic behavior of activities (farming, ranching, hunting, recreational, etc.) carried out in the park to preserve its biodiversity. Therefore, conclusions of the project will be integrated in the administrative tool that defines the general management plan of the Natural park, as additional requirements to the park activities.Item Experiences in introducing noise management processes: Particular needs require particular solutions(2005) Aspuru, Itziar; Vázquez, Manuel; Fernández, Pilar; CALIDAD Y CONFORT AMBIENTALDifferent 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).Item Methodology to evaluate the efficiency of additional devices on noise barriers(2009) Díez, Itxasne; Fernández, Pilar; Vázquez, Manuel; Tecnalia Research & Innovation; CALIDAD Y CONFORT AMBIENTALDue to the interest in reducing the noise quality in the vicinity of roads, it is very common to find anti-noise devices on their banks. The continuous growth of roads and vehicles have required the need to improve the effectiveness of barriers, putting on the barrier additional element called top device (cap, top barrier, crowning). This paper presents the first results obtained during the MAITE project "Transport infrastructure noise attenuation: design and system modelling of additional devices to optimize the effectiveness on diffraction edges", based on calculations to evaluate the effect of the top edge of the barrier. The Harmonoise reference model has been used to choose the propagation method for evaluating the diffraction effect either in the source region and receiver region. The intrinsic characteristics of sound diffraction of added devices have been assessed according to the European technical specification CENT/TS 1793-4. Finally, it is also presented the results obtained by numerical simulations using a Boundary element method, in order to verify the results achieved in the measurement campaign.Item Spanish law affects the spatial and urban planning(2012) Aspuru, Itziar; Garcia, Igone; Fernández, Pilar; CALIDAD Y CONFORT AMBIENTAL; ADAPTACIÓN AL CAMBIO CLIMÁTICOThe new Spanish law, made by Law 37/2003 and Royal Decrees that develop it (RD 1513/2005 and RD 1367/2007) came up with the momentum of the European Noise Directive. It meets the objectives of doing Noise Maps and Action Plans, which should correct the existing conflict situations, prevent the creation of new conflicts and preserve areas with good sound quality. In this paper we want to emphasize the substantial effect of this law on the procedures and instruments of territorial and land planning. The paper analyzes the content of the law and its consequences in the daily practice of urban planning technicians and environmental agencies to review the changes in urban planning. It also presents the barriers found to the implementation of the legislation and it explains some proposed tools to facilitate the new tasks to be developed by technicians not skilled in acoustics and to adapt the deepness of the studies to the size of the potential problems to prevent.
