Abstract: | A computer program for the determination of the impulse response of rooms, using the mirror image method, has been developed. It is intended for acoustical planning of auditoria and the simulation of sound fields. The computer also generates the necessary information for the automatic mixer, delay unit and reverberation unit, which makes it possible to change sound field simulations in a short time.The program allows arbitrary room shapes to be analyzed by representing curved surfaces with plane approximations. The program also calculates energy time gaps, radiation angles and angles of incidence for the investigated source and receiver positions. The absorption coefficients of the reflecting surfaces are also taken into account. The source and the receiver may be positioned anywhere in the room. Compared with other programs described in the literature, this program yields more information, necessary particularly for electroacoustic room acoustics simulation and acoustical planning. |
