The TRANSIT project: innovation towards train pass-by noise source characterisation and separation tools
The TRANSIT project: innovation towards train pass-by noise source characterisation and separation tools
In TRANSIT, experimental methods are developed to separate and characterise noise sources on moving trains. Improved
microphone array techniques allow quantification of sound power and directivity. Source separation methods based on the PassBy Analysis method, Advanced Transfer Path Analysis and the TWINS model are also developed. For trains at standstill, new test
methods are developed to quantify noise transmission paths from sources to the standard microphone positions accounting for
installation effects. Several measurement campaigns are used to demonstrate and verify these methods. In addition, innovative
materials and methods are investigated for improved sound comfort in trains. Approaches considered include optimal sound
absorption at the source, attenuation along ducts for air conditioning systems and innovative meta-structure designs for the carbody parts

Abstract
In TRANSIT, experimental methods are developed to separate and characterise noise sources on moving trains. Improved
microphone array techniques allow quantification of sound power and directivity. Source separation methods based on the PassBy Analysis method, Advanced Transfer Path Analysis and the TWINS model are also developed. For trains at standstill, new test
methods are developed to quantify noise transmission paths from sources to the standard microphone positions accounting for
installation effects. Several measurement campaigns are used to demonstrate and verify these methods. In addition, innovative
materials and methods are investigated for improved sound comfort in trains. Approaches considered include optimal sound
absorption at the source, attenuation along ducts for air conditioning systems and innovative meta-structure designs for the carbody parts
