Radiation efficiency of acoustic-excited plates with stringer attachments
2007 (English)In: 14th International Congress on Sound and Vibration 2007, ICSV 2007, 2007, 3782-3789 p.Conference paper (Refereed)
The average radiation efficiency of acoustic-excited plate with stringer attachments is investigated by using a modal expansion method. This work is an extension to author's previous publication (JSV 2007), where the predicted and measured sound transmission loss for curved aircraft panels was reported. For the plate and frequency range studied here, numerical results reveal that the radiation efficiency of acoustic-excited plate is very sensitive to the damping of the structure. Increasing the structure loss factor significantly increases radiation efficiency far below the plate critical frequency.
