Sažetak
Zagreb City Zoological Garden (Zoo) is situated within Maksimir Park, established by the end of the 18th and in the first half of the 19th century, on what then were the border areas of the city. Today, the Park is almost entirely surrounded by residential and business areas, and, immediately next to the Zoo, there is a road exceptionally burdened with road and tramway traffic. The problem of increased noise levels in public parks and other recreation and rest areas has not been given a major attention, until today. Increasing complaints by employees and visitors of the Zoo motivated the Management to start the procedure for improvement of the existing state with respect to noise protection. The elaboration of the study of noise protection walls, as optimum way of protection in urban areas, was entrusted to the Civil Engineering Faculty, University of Zagreb. The paper presents a comprehensive procedure for implementation of the noise protection measures (measuring, calculation, protection) of the Zagreb Zoo. The measurements of the traffic noise levels were carried out within the Zoo grounds and on the outer side of its fence immediately next to the road. The measured levels of noise were used for verification of the acoustic calculation, elaboration of the noise propagation model, and production of noise maps for the existing noise levels. After the verification of the model, production of noise maps of the future state - with protection walls - was approached. During optimization of the position, length, height and type of the walls, the fact that the protected area is a monument of park architecture and a protected cultural good was taken into account as well as the fact that it represents an antique, but also a living part of the city for which it is necessary to keep and preserve its leading place among the historical sights, along with the application of the modern approach of protection.
