Elephant's amazing voice range.

Elephant Communication

An elephant’s vocal cords are so huge that the basic frequency of the sounds they produce is 20 cycles per second or less—well below the range of human hearing.

Such deep rumblings carry well, and elephants can recognize them from a mile [1.5 km] away.

They can also identify as many as 150 different calls, responding positively to the signals of family members and those bonded to their group.

Usually elephants ignore the calls of strangers or become agitated at hearing them.

Such extensive networks of vocal communication have not been demonstrated in any other mammal.
