The vibroacoustic quality of the coaches has been improving over time, being these more accented in recent years. This fact is due to the increasing number of users, and their demand for higher comfort. In order to implement on solutions that improve the vibroacoustic comfort, it is necessary to identify and quantify the noise and vibration sources, and their transmission paths. On this assignment, once the main sources of noise and vibrations (engine, transmission group, rolling motion and aerodynamics) have been characterized, a comparative analysis has been carried out in different operating modes (1400 r.p.m., 100 km/h, idle, ...) to evaluate vibrations on different parts of the coach as windows panes, side panels, floor and roof. This analysis has allowed the obtention of the contribution of each source to noise and vibration levels inside the cockpit in different frequency ranges.
