Abstract
This paper describes the prediction based on the experimental data for the peak SPL (Sound Pressure Level) of aerodynamic sound radiated from cylindrical bodies. The experiment is carried out in both cases of with and without endplate. First, the peak SPL was measured using 3 different type nozzles and 3 different cylindrical bodies. Second, the fluctuating lift coefficient was estimated by using the SPL data, the correlation length which were obtained in the experiment and the simplified Curle's equation. Finally, the predictable expression was presented and the predicted value was compared with the measured one. This expression was found to be useful for the prediction of the peak SPL of circular and square cylindrical bodies. Moreover, the occurring threshold of the Aeolian tones could also be obtained.
