Why can't humans hear the sound of a bat?

Bats use echolocation to sense movement and their surroundings. We cannot hear the high pitched noise they emit because it is of a higher frequency than the human ear can register. There are some sounds of a bat that we can hear, but the sounds that we can't hear is because the squeaks are so high that you really need ultrasound to hear it.

Why can dogs hear more sounds than humans?

Yes. "Dog's sense of hearing has an almost equally important role within their world. Not only do dogs have a highly developed sense of hearing that can hear a wide range of sounds but they also have the ability to pin point the exact origin of the sound, discriminate between sounds and make a accurate interpretation of the sound, and decided whether it is threatening or non-threatening. As dog's ears are able to move in different directions, it is easier for dogs to pinpoint the exact location of a sound's origin. The frequencies that dogs can perceive and hear are almost twice that of humans and they can pick up and distinguish sounds at roughly 4 times the range of humans. Dogs have specially designed inner ears that allow them to have this incredible ability and their ears operate almost like radars. Not only do dogs hear the sounds but also perceive the height and depth of the sounds that they hear. Dogs also have the ability to hear ultra high frequencies that humans cannot and many professional dog handlers and trainers use this ability to their advantage by teaching them and training them to respond to different commands given on whistles that produce ultra high frequency sounds.
