ANimals have a wider range of tones some can be too high and some may be too low for us to hear Animals Ears are more sensitive than ours
Animals that have pointed ears usually can hear better. Animals that have floppy ears can't hear as well.
dog
Dolphins and bats
Because there eardums are bigger then ours
Yes, they can see and hear things humans can. They can hear and see a bit better than us, too.
So they can hear better, and hear if a predator is approaching them.
I don't think that there is an animal that can see better than a human... But there are animals that can hear better, such as cats, dogs, deer, etc.
elephants need to hear better because they communicate* in a lower frequency which means we cant hear them communicate* but they need better ears so they can hear each other *they communicate in low frequency drone's like bird tweeting except they are a lot lower and we cant hear them
Usually, Really big ears help them, And Animals for some reason just automatically have better hearing then humans. But if you are referring to dolphins, and whales and aquatic animals, It is the density of water. Sound travels better through denser materials.
Some animals have large ear flaps so they can hear more noises better and louder.
Animals can almost always see and hear things the way humans can. Some of them can also hear and see things that humans cannot. For instance a dogs hearing and a cats sense of sight are much better than a humans are.
YES! i think that dolphins have 15 times the hearing we do
