beat tone meaning in Chinese

拍音

The 21 - year - old at the other edge of the earth , accompanying with the playing shoes sound from the stage of the living theater , the sound of the steam - whistle when a train is passing by , the sound of falling leaves , the sobbing voice , the busy noise of telephone & radio , the tone of the growing - up footstep , the voice of saying good - bye , the beating tone of the heart , hurry up
地球那一端的二十一岁，伴着舞台剧笃笃的皮鞋声，火车轰鸣而过的汽笛声，落叶的唰刷声，抽泣声，电话的忙音声，收音机的兹兹声，成长中的脚步声，道别声，心脏的跳跃声，匆忙而至。
