Kartiranje hrupa na osnovi usmerjenosti imisije

Šilc, Janže (author), Prezelj, Jurij (mentor)

Predstavljena je metoda merjenja hrupa, ki na podlagi oddaljenosti in kota zvočnega vira od merilnega sistema določa povprečno zvočno raven hrupa v okolici. Predpostavili smo hipotezo, da lahko s štirimi diferencialnimi mikrofoni določimo smer in zvočno raven dominantnega vira hrupa v okolici. Na podlagi teh podatkov pa lahko izdelamo karto hrupa okolice, kjer smo izvedli meritve.

• Title: Noise mapping based on measurements of immission directivity

Abstract

A noise measurement method is presented which determines the average sound level of the surrounding noise based on the distance and angle of the sound source from the measuring system. We assumed that with four differential microphones we can determine the direction and sound level of the dominant source of noise in the surrounding area. On the basis of this data, we can create a map of ambient noise where we performed measurements.
