Estimation technique of aerodynamic sound radiation from a cylindrical body using results of partial-span CFD computation is presented. The technique replaces the calculation of Curie equation in Lighthill-Curle computational aeroacoustics technique, and is based on Morse-Ingard's and Goldstein's theory and coherence model function. The validation of the model function and the technique through wind-tunnel experiment results 1) measured coherence between surface fluid forces on the body surface shows good agreement with the model function, and 2) reasonable agreement is obtained between measured SPL at a receiving point and estimated SPL using the technique.
