Sažetak
Measuring procedure of achieving energy-time curves (ETC) is supported by time delay spectrometry (TDS), which is implemented in time-energy analyzer (TEF). The objective parameters: clarity (C), definition (D) and ratio between reflected and direct energy (R) are defined with reflected, direct and total energy. The relations are set in order to enable estimation of other parameters based on measurement of only one energy parameter. Based on measurements in two architectural identical, but according to acoustic characteristics two different rooms, and additional analysis and calculations connected with number of people in a hall, objective parameters are evaluated according to earlier adopted optimal conditions involving certain deviations from the values.
