Optimal reverberation time

The necessity of determining the optimum reverberation time in relation to the purpose of the room appears as a problem during the design and modeling of room acoustics. The paper discusses different recommendations for determining the optimum reverberation time, which are analyzed graphically and numerically. Since reverberation time is a frequency- dependent function, the optimal frequency response characteristic is analyzed as well due to the frequency dependence of the absorption coefficient. Based on the so proposed criteria for selecting the optimum reverberation time value and its optimal frequency characteristic, it is possible to adjust the room and building acoustics in order to obtain optimal values of the acoustic quality of room.
