Do fishes and birds hear noise?

Yes. \nFishes only have internal ear, that is to say, no opening to the body surface and no tympanic membrane, but the vibrations (sound waves) are transmited from the water to the inner ear through the body tissues. Sound travels really well inside the water, even if we (with our land-adapted hearing system) cannot hear much of it. \nIn addition, some groups of freshwater fishes have a special system that enhances sound hearing. This is called "Webberian apparatus" and consists of a chain of small ossicles (derived from the first trunk vertebrae) that are situated between the swimming bladder and the internal ear. Thus, when sound waves contact the swimming bladder (which acts like the membrane of a drum), it is amplified and transmitted to the inner ear by means of the vibration of these small bones. The fishes that possess this system (known collectively as "ostariophysean" (Ostariophysi) include well-known species such as catfish, tetras and characins, carps, and the electric eel. \n\nBirds, as all tetrapods, _do_ have a middle ear, but with only one ossicle (we mammals have three). They don't have external ears, but they have a short external auditory meatus (duct) so the tympanic membrane is not on the surface (as in frogs). Sound makes the tympanum vibrate, this vibration is transmitted through the ossicle (columella auris) and goes to the inner ear.

Birds hear a lot better than we do, and worms moving around in soil make noise that is distinctive. OR, maybe they have Xray vision! :-)

Yes it has supposedly been proved that cows do. I saw it on the news.\n\n'Cows have regional accents like humans, language specialists have suggested. \nThey decided to examine the issue after dairy farmers noticed their cows had slightly different moos, depending on which herd they came from. \n\nJohn Wells, Professor of Phonetics at the University of London, said regional twangs had been seen before in birds'\n\n\nCheck this BBC article.\n\nhttp://news.bbc.co.uk/2/hi/uk_news/5277090.stm

I agree with big brain, they are some of the most efficent and dangerous killers in the animal kingdom. \n\nAlthough they do have communication patterns. Male crocodiles let out a low grunt when they are searching for a mate. And baby crocodiles let out a high pitch grunt when they are in danger. Not too sure about the sharks though.\n\nMost of the time though as big brain said they are solitary animals.

Yes, fishes sleep.\nNo, they sleep with their eyes open.\nYes, they stop swimming and are like a frozen statue in water except with eyes open.\n\nThey wake up from the slightest motion such as someone passing by, or lights going on in the room it is in.

Yes they do. They make bleats and babies whimper. You can listen here: http://www.sandiegozoo.org/animalbytes/t-giant_panda.html

Is it possible that birds misunderstand whales?

It's difficult to classify many animals and their sense of 'hearing'.  Our own sense of hearing is an extension of our staticoacoustic sense, and is merely a finely tuned ability to detect and discriminate between vibrations in the air.  \n\nAny ability to detect vibrations in air or water media could be technically considered a sense of hearing, it is merely a question of degree.\n\nMany insects are sensitive to only one or two frequencies of sound, and hear those sounds very well, but cannot hear any other frequencies.\n\nFish sense vibrations along their lateral line system, and detect all frequencies pretty much equally well, but often cannot discriminate between them.  So they could tell that someone was talking, but they wouldn't be able to understand what they are saying (even if they did know English).\n\nBoth geckos and hummingbirds have senses of hearing fairly similar to our own.  Geckos are one of the few lizard groups that have members that actually make noise to call mates.  The name of the group is taken from the sound that some of them make (which allegedly sounds like 'geck-oooh, geck-ooooh').  House geckos (Hemidactylus frenatus) are sometimes known as chit-chats because they babble to themselves.\n\nHoneybees and ants do not have particularly good hearing, but they are sensitive to certain specific frequencies.  It would be incorrect to call them completely deaf, but their hearing is definitely not as clear, nor has the range of almost any vertebrate.

The question really boils down to weather we define "sounds" by that which is heard, or the physical vibration of air molecules (we can also define vibrations in other fluids, like water, as sounds). \n\nObviously, when a tree falls in a forest it creates a massive vibration of air molecules, but if we define a sound as only the impulses transmitted from our inner ear to our brain and the recognition of these transmissions, then we can say that the vibrations from the tree fall became inaudible before reaching anyone's ears and therefore produced no sound.\n\nWe must also consider the other species, especially animals who have ears and brains and respond to aural impulses. Surely any forest will have such creatures within earshot of the falling tree. It would be arrogantly anthropocentric to define sounds as only that which is heard by humans.

Yes it would still make a sound eventhough there is no one there to hear it because sound waves would be generated. I think the philosphical question asks whether it make a NOISE. There is a difference between a sound and a noise. A noise is a sound that is loud and unpleasant. That is a judgement call; therefore, it would necessitate someone there to hear it and make the call.

If they were close enough to hear it.Yes...if not...no sound is made....sound consists of a transmitter (tree) and a receiver (ears) if one is missing then its not sound.\n\nGood Luck

Humming Birds have the highest frequency

I bet I have seen more platypus than the lot of you put together and i have never heard any noise apart from the gentle splash as they duck (no pun intended) beneath the surface. However, if you were to be stung by a male platypus in the breeding season you would make a LOT of noise. They are the most venomous mammals in the world.

Yes fish sleep.They cannot close their eyes because they do not have eye lids.some fishes sleep with their one half of the brain at a time so that the other half is active n helps the fish in escaping predators.Some fishes sleep at the bottom n few float while sleeping.Some have particular sites for sleeping as we have beds.

Giraffes vocalize at an infrasound level - sound at a frequency too low to be heard by a human ear.

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.

Giraffes make a very limited number of sounds that are audible to the human ear (grunts, snorts, etc.).  The majority of their vocalizations, however, are produced at frequencies that are imperceptible to us (infrasound). \n\nResearch suggests that their vocalizations may be designed to be a covert form of communication.  \n\nOther animals have been observed to communicate via infrasound and include okapi, elephants, whales, and rhinoceros.
