Attractive Train Interiors: Minimizing Annoying Sound and Vibration

Orrenius, U. / Carlsson, U.

A study of annoying sounds and vibrations generated by train interiors is reported. Different types of annoying sounds are discussed with respect to the effects they have on the passengers and a notation for distinguishing annoying sounds on trains is defined.

A survey of disturbing sounds and interior vibrations on Swedish intercity trains is also reported. A large majority of the annoying sounds found in the survey were of tapping or rattling character, originating from components like ceiling panels, light covers, cabinet doors, interior sliding doors and foldable tables. For some vehicles the number of annoying sounds and vibration issues related to interiors is substantial also for cars with only a few years in operation. This observation underlines the need for systematic abatement procedures and proactive measures from the manufacturers and operators to ensure comfortable train journeys.

A review of processes applied in the automotive sector to control annoying noises is also summarized and opportunities for knowledge transfer to the railway industry are discussed. Finally, best practice design solutions to reduce interior vibrations and annoying sounds from train interiors are summarized in view of the results of the present survey and previous vehicle design experience.
