Abstract

In order to visualize the transfer of sound waves, we performed real-time processing with the fast operating system of GPU, the Graphics Processing Unit. Simulation by using the method of the discrete Huygens' model was also implemented. The sound waves were visualized by varying the real-time processing, the reflecting surfaces within the two-dimensional virtual sound field, and the states of the sound source. Experimental results have shown that reflection and diffraction patterns for the sound waves were identified at the reflecting objects.

본 연구에서는 음파전달의 가시화를 위해 고속 연산장치인 GPU(Graphics Processing Unit)를 이용하여 실시간 처리를 하였으며 이산 호이겐스 모델법을 사용하여 시뮬레이션 하였다. 실시간 처리와 2차원 가상 음장내의 반사물이나 음원의 상태를 변경하여 실재 음장과 같은 음파전달의 가시화를 하였다. 그 결과, 음파가 반사물에 의해 반사되는 형태나 반사물에서 회절하는 형태가 확인되었다.
