Silence in the interior of a vehicle is indispensable for a passenger taking a Shinkansen vehicle to have a comfortable time. However, in JR East, since we are working for the further speed up of Shinkansen, the silence in the interior of a vehicle is declining with further speed up and interior noise tends to be increasing.
