can animals hear many more sounds than humans can?

This depends on the animal, a number of different types of animals can hear much better than we can.  However there are some animals like turtles and snakes that can only hear very low frequency sounds.  In spite of what many people think neither turtles or snakes are actually deaf.  Some of this has to do with the anatomy of the ear.  Mammals have 3 ear bones; the stapes, the malleus and the incus.  While fish only have a stapes.  This was the result of evolution so that animals could develop better hearing for a number of different reasons such as 1) better hearing required on land as sound travels better through water than land and 2) the development of a means of communication between one another.  These are the only 2 i can think of off hand but there is a lot of interesting information about the evolution hearing in animals out there.

There are a number of misconceptions about giraffe. One is that they cannot make any sound. Although generally quiet, they have been heard to grunt, snort and bleat.

Humans like to think we are special and unique and different than our animal brethern, but are we?\n\n1. We share many characteristics, instincts, genetics, phenotypes etc with animals\n\n2. We use tools, but so do many animals, contrary to what was believed previously.\n\n3. We have languages, but the animals appear to as well, and appear to be able to understand some of language (dogs, horses, chimps). Some animals, like chimps, have been taught to use sign language and even type on computers, and some claim appear to use language creatively. \n\n4. Some animals have similar ratios of brain mass to body mass as humans, or even have better ratios. Many cetaceans might be as intelligent as humans, but not have the ability to manipulate the environment in the same way since they do not have hands. \n\nSo the entire premise of this question is a bit suspect, frankly.

Bats send out high-frequency sounds and receive them back through their ears. They actually get a mental picture of the area around them just like we do with our eyes. When a bat gets a food source in its hearing vision, the frequency gets even higher and more frequent so it can narrow down on it.

Actually, no it doesn't. The sound you hear is actually vibrations in your ear that your brain converts to noise. So if there are no living creatures with ears and brains around to 'hear' it, it does not make a noise...just some air vibrations going all over the place.

mammals, reptiles hav vocal cords,,, others dont!!!

Lots of thing have more than the 5 senses we are used to. Bats and toothed whales use sonar, fish have lateral lines, sharks can pick up electro signals. Snakes and animals with whiskers can sense vibrations with their tounge and whiskers respectively.

No, not the way animals do. Animals can actually smell fear with their noses, it has an actual scent to them. But humans can sense fear, not smell it, but they have intuition and feelings, perceptions of body language, tone, reason, common sense, that let a person just know when someone is afraid.

Nope.  No sound.  Soundwaves, yes.  Without the diaphram of the eardrum vibrating there is no such thing as sound.  Of course woodland creatures would hear it, most of them have eardrums too. (as oppose to snakes) Sound does not exist on it's own, it does indeed need a reciever to actually be considered sound.  So, taking away all creatures with an ear as a reciever... the tree will only make soundwaves.

No, but it probably feels vibrations, which is kinda like hearing.  Snakes don't have ears, but they "hear" vibrations.

All species of dolphins use sound for echolocation. Using their melon (the bulbous portion of their forehead), they create a sound that bounces off objects around them. The returning echo of the sound gives the dolphin information about the location and physical description of the object. I don't know much about the actual workings of the brain though, but I do know that the dolphins sonar is much more advanced than human technology and can pin point exact information about it's surroundings ranging from size, distance and even the nature of the object. Dolphin Speech is so complex that the sounds even cross the species barriers and enable different kinds of dolphins to communicate.  They have been known to instruct each other as well as receive instructions and act accordingly.

While in dogs most of the communication they do would translate, there are some animals that definitely do show dialects in their calls.\n\nOrcas are the most obvious example.  Different pods have totally different repetoires of calls, whistles, grunts and clicks, and when a whale from a different pod is encountered, the new whale may be shunned or moved to the bottom of the pecking order until he learns the new dialect.

As many sounds as you can hear.  Some people are hard of hearing on high or low sounds.

According to science Dogs do have the sense of hearing sound waves beyond and below the human hearing levels. (20000Hz and above, 20Hz and below)\n\nAnd they also possess the great ability to sense things through smelling them! (Sniffing!)\n\nWith these two great senses that are graded higher than human senses, i assume that it has the ability of understanding a vehicle that could be in distance, by hearing it and simply sniffing you close-by.\n\nBut, if you believe in angels and demons, then the daredevil is close-by and the dog, can see him waiting for you!

Well, yes we do. As long as the ears are correct, we'll hear the same. BUT, how our brain reacts to what we hear is a totally different matter. Since the brain is trying to make sense of what our ears receieve, then we know for a fact that we all will hear something different from each other, simply because all the ears in the world aren't connected to the same brain....

Humans have a higher brain function and can make choices.  Animals are just animals and don't stop to think about where they should do it, they just do it.

As with many other sensory handicaps the other senses get much more acute. Yes many people do use seeing eye dogs and many cities use the tones but many blind people do not have these and get along just fine. The hearing of blind people is normally exceptional and they are able to hear traffic and others crossing.
