In this paper, the potential of the scale model experiment for room acoustics using a new model scale of 1/16 (62.5% the size of 1/10 model) is studied both in principle and in practical application. First it was shown that in principle it is possible to clarify the influence of air absorption and exclude the influence by nitrogen substitution just as well as can be done with a 1/10 scale model. Secondly, design specifications for the human body in the 1/16 scale model with equivalent sound absorption characteristics to the acknowledged 1/10 scale model were found by conducting a sound-absorbing test using the model reverberation room. Room acoustic models were then constructed in 1/10 and 1/16 scale, simulating the same auditorium, in which reverberation times, initial sound reflection properties and frequency responses of sound transmission were investigated for a simulated frequency range from 90 to 5,600Hz. As a result, it was confirmed that the same physical values can be obtained practically in both the 1/10 scale model and 1/16 scale model.
