This deserves a proper investigation by an independent acoustic professional. A comprehensive noise survey within the train compartment should be carried out at the problematic track sections, using a precision sound level meter to sample the noise exposure whilst recording the average train speeds. Weather conditions, time and date, and level of passenger loading of the EMU also should be recorded.
