Abstract
This paper presents analysis results on the acoustic radiated power from the rubber-inserted flat acoustic window of sonar dome, which is excited by pressure fluctuation of turbulent flow. Analysis is based on the well-known RKU theory, Corcos model and modal approach. It is found that increasing the loss factor has less effect on decreasing the radiated sound power despite of significant decrease of vibration level. In addition, increasing the thickness of the rubber layer, under same total thickness, can increase the vibration level in the high frequency range. However, the acoustic radiated power is similar or less than that of the thinner rubber layer.
