| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In recent years, the noise reduction of the cars is motivated with the spread of electric vehicles and hybrid vehicles. From this result, a pedestrian cannot detect the sound of approaching car, and many accidents were occurred. Therefore, the acoustic field analysis of moving sound source is desired for the settlement of the problem. Finite Difference Time Domain (FDTD) method is a one of the effective method for acoustic field analysis. In the present study, Overset Grid method is adopted for FDTD to treat the moving sound source problem. Results of the computation show that the sound pressure level in the intersection road has 15 dB gaps compare with the value of the straight road. |
