Sažetak
As a part of the reconstruction of the early warning system in the event of an accident on the Peruća hydropower dam, the acoustic alarm system using sirens was designed. For the purpose of overall design the mapping of sound propagation was made in order to predict the levels of sound in the imission area. The criteria for the imission alarm sound levels were established based on the measurement of background noise carried out on various strategic positions within the endangered area. The sirens were modeled as industrial sources according to EN ISO 9613 method, performed by the noise mapping software for the calculation of sound propagation and coverage. The unknown sound power of such a source was calculated from generic sound pressures and directivities of sirens present on the market. In the iterative process, the number, optimal position, sound level and directivity of the sirens were determined for attaining the required alarm levels and the optimal sound coverage of over 400 km2 of the endangered area.
