The transient sound radiation monitor of a free beam by a single point vibration measurement

Methods to reconstruction the whole beam's vibration by a single point vibration measurement was discussed. The vibration field was used to calculate the transient sound of the free-free beam, and then the beam's transient sound radiation prediction method was given. The method to monitor the sound radiation of the beam by single point vibration measurement was valid by experiment. At last, the best position to place the vibration sensors was discussed by numerical simulation.
