What do we know in room acoustics?

چکیده
Room acoustics has a scientific interdisciplinary concept which will be further developed in future. During the last century, several dimensions of the overall listening impression in concert halls were identified which show a good correlation with corresponding objective measurement data. It can be summarized that the three most important factors (loudness, reverberance and spatial impression) explain most of the statistical variance when comparing the acoustic conditions in auditoria. But some questions remain, particularly for stage acoustics, for dependencies within the quantities and for the overall impression. In applied room acoustics, progress can be seen concerning modeling and simulation on the one hand, and impulse response measurements on the other. Apart from the perceptual factors of room acoustics, another crucial point is the listener’s sensitivity to changes in a sound field in regard to those subjective aspects. In the end, the uncertainties of simulation and measurement results must be compared with the just noticeable differences, jnd, of hearing in rooms. Thus, further cooperation of room acoustics with psychoacoustics and audio engineering is expected to stimulate more ideas and innovation in research and concert hall design.
