摘要：

Any sound source of limited dimensions looks like a point source for observers at great distance. The transition points to line source or plane source behaviour of the sound attenuation with distance are shown to be simply related to the characteristic dimensions of the source. For the calculation of the attenuation introduced by an acoustic barrier a new approach immediately gives the attenuation spectrum. It can be used to make a universal attenuation template. © 1969.
