Določanje lokacij in zvočnih moči zvočnih virov iz usmerjenosti imisije zvoka

Bratuž, Erik (author), Prezelj, Jurij (mentor)

V zaključni nalogi smo preverili hipotezo, da lahko z merjenjem usmerjenosti imisije okoli industrijskega terena izdelamo karto hrupa, ki lahko določi lokacije zvočnih virov in jim pripiše oceno zvočne moči. Izbrali smo industrijsko območje in določili 7 merilnih mest. Za vsako merilno mesto smo izmerili usmerjenost imisije hrupa in izrisali polarne diagrame. Z izmerjenimi podatki smo izdelali karto hrupa. S tem smo pokazali, da je izdelava karte hrupa z ocenami zvočne moči izvedljiva.

• Title: Determining the locations and sound power of sound sources from the directionality of sound immission

Abstract

In this final thesis, we examined the hypothesis that by measuring the directivity of sound immission around an industrial area, we can create a noise map, capable of determining the locations of sound sources and attributing them with sound power estimations. We selected an industrial zone and identified 7 measurement points. For each measurement point, we measured the directivity of sound immission and plotted polar diagrams. Using the collected data, we created a noise map, thus demonstrating the feasibility of generating a noise map with sound power estimations.
