Room acoustics simulator and auralizer

U ovom radu opisan je matematički model zvuka. Opisano je nastajanje zvuka u nekoj prostoriji na mjestu slušatelja, što podrazumijeva opis direktnog zvuka, ranih refleksija i odjeka prostorije. Uz te opise, kratko je navedeno što je to akustički komfor i kako su navedeni modeli primjenjivi u stvarnosti, te zašto je akustička obrada prostora bitna. U privitku rada nalazi se programski kod za simulator akustike prostora, a u radu su opisane metode simulacije zvuka na računalu općenito, kao i konkretna implementacija simulatora iz privitka.This paper describes a mathematical model of sound. The formation of sound in a room in the place of the listener is described, which implies a description of direct sound, early reflections and impulse response of a room. In addition to this, the paper briefly describes what acoustic comfort is and how the examples given are useful in reality, and why acoustic treatment of rooms is important. Attached to the paper is the program code for the room acoustics simulator, and the paper describes the methods of sound simulation on a computer in general, as well as the specific implementation of the simulator from the attachment
