Interior and exterior noise and vibration measurements in the new Alstom-CAF units for FGC

In order to validate the acoustics of the new Alstom-CAF railway units for FGC, ICR has carried out noise measurements according to TSI, ISO 3095 and ISO 3381 standards and simultaneous noise and vibration measurements near trailer and motor bogies.

ICR has carried out noise measurements in different operating conditions:

·         Vehicle at standstill:

o    Measurement of interior noise levels.

o    Measurement of exterior noise levels

·         Vehicle running in different conditions:

o    Constant speed: measurement of interior and exterior pass-by noise levels

o    Acceleration: measurement of interior and exterior noise levels

o    Braking: measurement of interior and exterior noise levels

Noise and vibration measurement near bogies was carried out in all conditions.

This set of measurements has allowed ICR to determine the noise levels of the vehicle and to obtain a complete acoustical characterization of the train.
