The elephant can hear infrasonic sound waves
An elephant’s sense of hearing is incredible. They are capable of hearing infrasonic sound waves, which are too low for us to detect. Their range isn’t all that impressive -roughly between 16 and 12,000 hertz, compared to our 20 to 20,000 hertz.
However, they’re capable of recognising calls and voices from other elephants, and use their hearing in a social manner. They can also use their enormous ears to funnel in sound waves, the way you would if you cupped your hand around your ear, but on a much larger scale.
