For the train-cars that were introduced to the Tokaido Shinkansen line and Sanyo Shinkansen line following 100 series Shinkansen train-cars, and for those of the Shinkansen lines other than the Tokaido Shinkansen line and Sanyo Shinkansen line, this sound was never taken up by the media.
また、新幹線100系電車以降の東海道・山陽新幹線車両や東海道・山陽新幹線以外の新幹線については、この音をメディアなどで取り上げられることはなかった。
