The paper presents a case history: the acoustical analysis of a rectangular auditorium. The following acoustical parameters were evaluated: early decay time, reverberation time, clarity, definition and center time. The excitation signal was linear sweep sine and additional analysis was carried out: peak to noise ratio, reverberation time for empty and occupied room, standard deviation of acoustical parameters, diffusion and just noticeable differences analysis. Conclusions about room’s destination and modeling were drawn in the end.

Abstract
The paper presents a case history: the acoustical analysis of a rectangular auditorium. The following acoustical parameters were evaluated: early decay time, reverberation time, clarity, definition and center time. The excitation signal was linear sweep sine and additional analysis was carried out: peak to noise ratio, reverberation time for empty and occupied room, standard deviation of acoustical parameters, diffusion and just noticeable differences analysis. Conclusions about room’s destination and modeling were drawn in the end.| File | Dimensione | Formato | |
