摘要：

After briefly reviewing the important mechanisms by which aerodynamic sound sources are generated on high speed tracked vehicles, two characteristic train speeds that quantify the significance of this noise are defined. The results of microphone array measurements are used to illustrate sound levels generated by flow interactions with a pantograph. Recent developments in measurement technology, analysis and hardware are then surveyed. (C) 1996 Academic Press Limited
