|Abstract:||Field measurements have indicated that train noise increases as one goes up a building. The study has shown that train noise has distinct vertical directivity pattern. As the angle of elevation increases from 10° to 30°, the train noise increases by about 7 dB(A) which is clearly perceptible. It correlates very well with more instances of complaints of train noise pollution from residents staying at higher levels of the block facing the elevated viaduct. © 1998 Elsevier Science Ltd.
