A Study on Prediction of Acoustic Field in Concert Hall with Suspended Sound Reflecting Panel |
| Abstract |
This study was aimed to predict the steady distribution of sound pressure in the practial concert room with suspended sound reflecting panels, and to observe the uniform convergency of the predicted solutions to the values measured by the scaled model test. The procedure of mathematical simulation for prediction was followed as;(1) Deriving the more general formula, in which the boundary conditions are contained,(2) Formulating and calculating the linear matrices of that formula, which was achieved by the boundary element method,(3) Calucating the steady characteristic of sound field, that is, sound pressure distribution.We could obsere the uniform convergency of the calculated solutions to the experimental values measured in the 1/17 scale-modeled concert room, in which the pure sound was radiated by the speaker systemsFinally, the simulation was shown to be very well suited for this kind of problems. And furthermore it can probably be used for more practical acoustic design. |
