The cones of larger loudspeakers used in traditional public-address systems vibrate more slowly, making them better suited for sounds in the range of human hearing.
传统播音系统使用的大型扩音器中的椎体振动较为缓慢，使声音更加适合人类听觉范围。
The sound waves were so huge (about 20,000 light years in length) and so low (about 50 octaves below hearing range) that the astronomer had to adjust them to the range of human hearing.
这种声波如此巨大(大约2万光年长)又如此低沉(大约低于听力范围50个八度)，所以天文学家对它进行必要的调整后，人才能听到。
