A listening room is a place where a recorded sound mixed with an appropriate amount of reverberation is reproduced, where we will hear first the direct sound from a speaker and then the reflected sound from the room surface. Since the direct sound is superposed by the reflected sound, the reverberant sound of a source heard by a listener in a room changes with the increasing amount of reflection. Such change is a qualitative one that gives us an impression of acoustic spaciousness of a hall. There is another quantitative change which is expressed here by the change of the definition of a sound. The calculated definition of reproduced sound in a room depends on the reverberation time of room and the acoustic structure of recording source (See Figs. 1-3). As a result, the reverberation time advisable for a listening room is shown in Fig. 4.
