This study was made to establish a practical method of correcting the effects of ground reflection on acoustic measurements of jet engine noise. The pressure reflection coefficient of the reflecting plane was estimated to correct the effects of ground reflection on acoustic radiation field through measurement of the distance-attenuation of a pure tone influenced by ground reflection. Examples of ground reflection correction for jet engine noise were demonstrated with reasonable results showing the practicality of the proposed procedure.
