Pass-by railway noise is one of the main problems in the community. Typically pass-by railway noise is estimated using Leq or Lden in dB (A) and often these methods do not reflect the listener perceptual overview. It is therefore necessary to reduce the pass-by railway noise by synthesizing the noise characters into various segments. The segments could be based on the physical properties of rail vehicles like rolling, traction, pantograph, cooling system noise, etc. There are few other segments which are also based on the perceptual view of the pass-by railway noise like squeaking, rattling or beating (tadak, tadak). Several pass-by noises from Swedish rail vehicles were recorded using binaural technology according to ISO 3095. Recorded noise signals were then synthesized with the help of spectrogram analysis using Matlab. Validated synthesized sounds were used to create the virtual railway sounds for more pleasant listening. The results of the studies indicate that the rolling noise and broadband noise are mostly annoying for the long distance passenger rail vehicles.
