The paper presents the acoustics analysis of three different enclosed spaces. These spaces (rooms) have different geometrical
shapes and sizes and serve for different purposes. The early decay time, reverberation time, clarity and center time are evaluated
with Dirac, WinMLS, Aurora and Caracad software using simple, low-cost equipment. The listed acoustic parameters were determined
using linear sine sweep and impulsive sources. Comparisons between experimental measurements, simulations and analytic results
were done. The room impulse response measurement proved to be the most reliable method to evaluate the properties of different
rooms even if the measurements are perturbed by non-idealities of the low-cost equipment. 相似文献
