Primerjalna analiza ukrepov, ki vplivajo na spremembo odmevnega časa v prostoru : diplomska naloga

Sušnik, Mija (author), Košir, Mitja (mentor), Jagličić, Zvonko (co-mentor)

V diplomski nalogi obravnavam ukrepe, ki vplivajo na spremembo odmevnega časa v treh različno velikih predavalnicah. V prvem delu naloge predstavim teoretično ozadje zvoka in odmevnega časa ter opišem nekatere izmed moţnih ukrepov za spremembo odmevnega časa. Temu sledi praktični del naloge, kjer so opisani postopki in načini izvajanja meritev ter grafično predstavljeni rezultati. Do njih pridem na tri različne načine, in sicer z uporabo merilca, s simulacijo v računalniškem programu ter z uporabo enačb. Primerjam vrednosti odmevnega časa praznega prostora, polnega prostora ter praznega prostora z zagrnjenimi zavesami. Dobljene rezultate ovrednotim in primerjam s slovensko zakonodajo. V zaključku predstavim še nekaj predhodnih študij s tega področja. Te potrdijo moje ugotovitve, da so izbrani načini za določitev odmevnega časa med seboj različni in imajo svoje omejitve ter da z različnimi ukrepi lahko vplivamo na odmevni čas v prostoru.

• Title: Comparative analysis of measures that affect reverberation time in a room : graduation thesis

Abstract

The thesis deals with measures that affect reverberation time in three lecture rooms of different sizes. In the first part of the thesis I present theoretical background on sound and reverberation time and I describe some of the possible measures that can change reverberation time in a room. This is followed by the practical part of the thesis in which procedures, methods of measuring and graphical presentation of the results are described. I use three different types of measuring reverberation time in a room - using the meter, by simulation in a computer program and using equations. I compare the values of reverberation time in empty space, occupied space and empty space with closed curtains. The results obtained are evaluated and compared with the Slovenian legislation. In conclusion, I present some preliminary studies in this field. They confirm my findings; the types of measuring reverberation time differ one from another and have their own limitations, and different measures can impact the reverberation time in a room.
