| Research Abstract |
This study is aimed to the developments of visualization method of sound fields or acoustic scattering objects, and also the implementation for the application of this method. As the results of this study, it has been proved that this method is suitable in heavily reflective sound fields, compared to other visualization methods. Especially in the space surrounded by reflective boundaries, the visualization can be achieved by using small number of array elements. Real-time visualization could be also possible with parallel computing by using graphical processing unit (GPU).
