Analysis of Acoustic Space Objective Quality Criteria of Orlí Street Theatre
Bělunek, Adam ; Frenštátský, Petr (referee) ; Schimmel, Jiří (advisor)
The core of the theoretical part of this work lies in a summary of basic laws and principles of a room acoustics, behavior of sound waves, reverberation time, sound absorption, impulse response and methods of measurement. Furthermore, the work describe and define some of the objective quality criteria of concert halls we know. We can find basic time criteria (e.g. reverberation time, early decay time, bass ratio, high frequency ratio…) and energy criteria (e.g. objective clarity, strenght of arriving energy…) etc.. The main focus is on a script, that is programmed in Matlab. It handles calculation of some objective quality criteria of concert halls. The function of the program is described. There are some trial calculation, that are evaluated. Functionality is demonstrated on some impulse responses, that were measured in hall of a theatre Divadlo na Orlí. The positions of microphones were different and also the configuration of acoustics elements in this hall was changing. Results were compared and commented. Another part of this work are scripts for calculations of impulse response and frequency response.
