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., 資料番号: NALTR0460000, レポート番号: NAL TR-460}, title = {音圧反射係数の測定法と地面反射補正について}, year = {1976} }
