5. Propagation
5.1 Noise on board
Acoustic comfort in the driver's cab, platform or passenger compartment is controlled both by the noise sources that contribute to external noise, and by the transfer paths between these sources and the passenger compartments.
These transfers are both aerial (panel transparency, passage through ventilation ducts, etc.) and solid (passage through bogie-case links, case-case shock absorbers, etc.).
Analysis of the air transfer paths, using SEA (Statistical Energy Analysis) methods, can be used to determine the contributions of the various sources and body components to noise in the passenger compartments
