quote from the web:
"Ears to Envy
Compared with humans, many creatures possess amazing hearing. Whereas we can hear sounds ranging from 20 to 20,000 hertz (cycles per second), dogs can hear in the range of 40 to 46,000 hertz, and horses, between 31 and 40,000 hertz. Elephants and cattle can even hear in the infrasonic range (just below human hearing) to as low as 16 hertz. Because low frequencies travel farther, elephants may be able to communicate over distances of two or more miles [4 km]. In fact, some researchers say that we could employ such animals to give us an early warning of earthquakes and severe weather disturbances—both of which emit infrasonic sound."
voilá.
