20.500.12556/DKUM-61197 Validacija računskega modela za vrednotenje hrupa v okolju z meritvami v realnih pogojih Validation of calculation model for evaluation of environmental noise with measurements in real conditions Ocenjevanje obremenitve okolja s hrupom lahko podajamo na podlagi izvajanja meritev hrupa ali z uporabo 3D akustičnih modelov, z uporabo računskih metod. Magistrsko delo obravnava postopek vrednotenja hrupa z uporabo računske metode za industrijske vire hrupa, ki temelji na standardu SIST ISO 9613-2, metode meritev hrupa v okolju, primerjavo med vrednostmi hrupa, pridobljeno z uporabo računske metode in meritvami v realnih pogojih, ter oceno računske in merilne negotovosti izvedenih meritev. 3D akustični model smo izdelali z računalniškim programom LimA, version 9.12, proizvajalca Stapelfeldt Ingenieuergesellschaft GmbH. V zaključku sta podani validacija računskega modela industrijskih virov hrupa s podrobno analizo računske in merilne negotovosti ter analiza rezultata. Evaluation of noise exposure may be provided on the basis of measurements of noise or by using 3D acoustic model, by using computational methods. The master’s thesis deals with a description of calculation methods for industrial noise sources, based on the method specified in the standard SIST ISO 9613-2, methods of measurement of environmental noise calculation and comparison of noise levels obtained by using calculation method and measurements in real conditions, assessment of calculation uncertainty and measurement uncertainty of the measurements performed. 3D acoustic model was created by using a program LimA, version 9.12, developed by Stapelfeldt Ingenieuergesellschaft GmbH. In conclusion we present the validation of the calculation model of industrial noise sources with detailed analysis and calculation of measurement uncertainty, and analysis of results. hrup akustični model karte hrupa meritve hrupa negotovost noise acoustic model noise mapping noise measurement uncertainty true true false [Z.
