Abstract

U ovom radu opisana je izvršena metoda mjerenja i prikaza trodimenzionalnog akustičkog odziva prostorije. Objašnjeni su pojmovi vezani uz akustiku prostorije te pojam impulsnog odziva. Također, opisane su postojeće metode za mjerenje impulsnog odziva, njihove prednosti i nedostaci te usporedba u odnosu na prostornu razlučivost ljudskog uha. Ukratko je opisana i potrebna oprema za mjerenje impulsnog odziva. Objašnjeni su koraci izvršeni tijekom mjerenja impulsnog odziva kao i tijek obrade i vizualizacije signala pomoću aplikacije kreirane u sklopu ovog rada. Rezultati mjerenja trodimenzionalnog akustičkog odziva prikazani su pomoću dobivenih grafova.

Abstract (english)

This paper describes methods used in performed measurements and displaying of three-dimensional acoustic response of the room. It explains terms related to the acoustics of the room and the concept of the impulse response. Also, existing methods for measuring the impulse response are explained, with their advantages and disadvantages, and compared relating to spatial resolution of the human ear. Necessary equipment to measure the impulse response is shortly described. This paper explains the steps performed during the measurement of the impulse response and the course of processing and visualization of signals using application built as part of this work. Results of measuring the three-dimensional acoustic response are shown by the obtained graphs.
