| Abstract: | This paper deals with the calculation of the transient sound radiation properties and the mechanism of sound radiation for an arbitrary shape three dimensional structure in time domain. It discusses theoretically and experimentally the relationship among external forces, vibration response and sound radiation, and provides a new numerical method of studying sound-vibration coupling properties and transient acoustic field. |
