Computer Simulation Of High Frequency Sound Field Impulse Response In Rooms

The methods(ray tracing method,mirror-Anage method,etc.)Which arebased on geometrical room acoustics are intrduced briefly, and at thesame time, the featUrrs of each method are given. Based on thes methods,using the conceP of sonic particles with changeable diameter, anadvanced mdsod fOr sthelating the boulse response of an acOUSticalfield in an enclosure is pointed out. Using visual Basic 6.0, an comPutersimulation program is given out, and in the program, the method ofchanging steP length is used Which greatly imProved the simulation sPeed.By the aid of the program, simulation testS are completed, and the resultsshow that the methOd is correct.Wu Bo(DePt. of Environment Engineering),Directed by pro f Zhao M, Jiang Genshan...
