ASSESSMENT OF THE ACOUSTICAL COMFORT IN HIGH-SPEED TRAINS AT THE SNCF: INTEGRATION OF SUBJECTIVE PARAMETERS

In order to understand better passenger perception, SNCF has recently begun new acoustics research. Usually, the acoustic comfort in high-speed train coaches is evaluated using the A-weighted sound pressure level. However, a preliminary psychoacoustic study has pointed out that this unit may not be the most appropriate one and that subjective factors have to be considered. To determine the most important parameters involved in the acoustic annoyance and the most appropriate unit, a new research programme has been planned.
