The Hearing of the Wolf

Hearing
Wolves have incredibly good hearing and can hear sounds up to six miles away, including some high-pitched sounds that even a ®human¯ can't hear, in the range where bats and ®porpoises¯ produce sound. Even when it sleeps, a wolf's ears stand straight up so it can catch sounds made by other animals at all times. This helps the wolf catch ®prey¯, and lets it know when ®danger¯ is near.
Their large, pointed ears act like big scoops to catch lots of sound. Unlike ®humans¯, wolves can easily tell what direction sound is coming from by turning their ears from side to side. The direction the ears are pointing when the sound is loudest tells the wolf which direction the sound is coming from, which can help them locate ®rodents¯ under a snowpack.
