Question

Why Elephants can hear low notes of sound ​

Answer 1

Elephants can hear low notes:

Elephants and whales can hear frequencies much lower (infrasonic sound) than the range of human audibility. Elephants are able to hear a sound coming from up to about 8 kilometers away. The distances from which they can communicate with each other is also amazing.

Answer 2

The human ear can hear many elephant sounds, but an intriguing fact is that some of their vocalizations are infrasonic, and thus are inaudible to humans. . Low frequency sounds (long wavelengths meeting little resistance) travel farther than high frequency sounds, which makes them ideal for long distance communication.
