| Abstract: | In this paper theoretical wall pressure fluctuation spectrum calculated by Rapid Distortion Theory was used to predict the effect of circular transducer size on the measured statistical properties of wall pressure fluctuation signals. It was found that the measured onedimensional spectrum has a significant decreaSe at hish wave numbers due to attenuation by the finite size of the transducer, and wall pressure fluctuahon intensity decreases with the increase of the transducer size. |
