How do Hearing Dogs help deaf people?

They hear what people say, and then tell their master the exact words.\nSometimes, when the master's hearing is too severely damaged, the dog would just talk to their master with hand/body signal.

APPEAR in front of me and:\n\nFor 24 hours, make me hear like a hearing person, so I know what it is like to hear "normally" before making me deaf again.  I am very curious about how hearing people actually "hear" with their ears without an aid, but would not want "normal" hearing for the rest of my life, though.  \n\nThen I might believe.\n\n(My deafness is genetic, not caused by disease or cancer or injury and never can be cured in my lifetime.)

If you are hearing impaired, you can ask for assistance from an usher. They can usually supply you with a device to help you.

Well yeah, id think so. Since they really arent talking with their mouths, but their hands. Thatll definitely be a question I have ask to my deaf friends. Thanks

Yes, from what I understand, coyotes use all of their senses of sight, smell, touch and hearing to communicate. \n\nThey are highly vocal mammals, using 3 distinct calls: squeaks, distress calls, and howl call, which consist of a quick series of yelps, followed by a high-pitched howl. Howling may act to announce where their territory is to other packs. \n\nCoyotes also howl when two or more members of a pack re-unite and to announce to each other where they are. \n\nLots more info here:

There is some good advice listed above.\n\nNetworking with other deaf people is a good way to hear about companies that hire the deaf.\n\nChecking with the State Department of Rehabilitation or Disabled Services or whatever its called in your state is probably the best idea.\n\nHow are his sign language abilities? A deaf friend of mine just graduated from college and she is now a substitute teacher at the state school for the deaf. Another deaf friend has very little education and he is a stock man at a warehouse.\n\nMy wife is very hard of hearing and she makes a very good living as a computer software consultant, most of which is done at home in front of a PC.\n\nHelp him to stay positive and have confidence in himself. Deaf people can do anything they want, except hear.

Because they are predators. Animals which do not rely so much on their hearing for hunting tend to have ears that are positioned to pick up sound equally well through 360 degrees as an early warning system.

good grief - there is a lot of 'part' knowledge here...\n\nyou need to break this down and talk about the different parts of what the original question was asking.\n\nif it was 'see', the explanation would be the same as for hearing by the way. (it would be easier to explain about seeing)\n\nhere goes...\n\ninside your ear you have these little hairs (cillia) that are a certain distance apart. when a sound wave enters the ear the wavelength of this wave will stimulate hairs at both its high energy points (its troughs or peaks, you choose, not important) your brain knows the distance of the hairs and so can interprut this wave distance between two lots of hairs being stimulated. thats how you get the frequency (number of wavelengths in a second) of sound in your ear. the volume (loudness) depends on how vigourously the hairs are moved by the sound wave. (thats why you can go deaf listening to loud music - you kill those little hairs if too loud). \n\nnotice i said sound!\n\nyour question is about electromagnetic waves. radio waves and visible light (green) waves are both of the same stuff (light energy - some we can see and some we cannot). the organ for detecting this energy is the eye. inside the eye, the retina (back of the eye) has special cells called rods and cones for detecting different wavelengths (i believe this is what your engineer was on about). each of these cells has a specific chemical for detecting a certain wavelength. lets pick on one.\n\nthe red light cone has a protein inside that has a special part that can move to a slightly higher energy form (a more awkward position for the proten so it wants to get back to where it was before - think of bending a ruler... the more you bend it, the more it wants to get back to where it was... so the higher the energy it has) when red light is shone on that protein (inside the eye) it provides enough energy to move this extra part of the protein (called an apoprotein portion is anyone wants to know) to a higher energy state and this is enough to induce (make happen) a signal being sent to the brain that says 'red light detected' and we see red light.\n\na similar thing happens to green light.\n\nin physics, when we talk of waves whether in music or lihgth or nanometers, if you have something of the same wavelength then it is detected as the same.\n\nif you have something of a different wavelngth then it is detect as different ( or in the case of the eye.. or even the ear, not detected at all, unless your are green, red or blue light)\n\nbut if you have a wavelength that is say  x2 bigger, of x3 or x6 or x2000 times bigger exactly, with no extra and no bits needed.. it has to be exact. then these also will be detected.. A BIT. we call thesse harmonics. this is a word that belongs to music.\n\never notice the way a piano has all those notes (only 8 notes and yet so many keys..?) these eight notes are repeated but in higher registers/keys, but they are still the same note.... a higher harmonic. all these wavelenths are doubled or trippled or what ever.\n\nso, because there will be a harmonic of green light in the radiowave part of the spectrum... it can theoretically be detected. so you could theoretically detect green light (with the eye) and radiowaves (theoretically with the eye)... but never with the ear :-)\n\nhappy days - now lets look at information theory! why do we always lose information and yet still maintain the integroty of the message? at what point is the message lost?

there are different organs used for hearing but the most common is the ears.\nThis is the organ that receives vibrations of sound transferred electrically to your brain where you get a sensation from the vibration commonly referred to as hearing.

I don't think they're deaf

Yes. It would be like saying things don't make sounds because deaf people can't hear it, It still makes sound, just no one is around to hear it.

I'm guessing your dog is the one barking? =0) Pet stores sell bark collars that either beep at a really high pitch when they bark to annoy them or there are ones that beep first to warn them and then deliver a mild electric shock if they don't stop. We had a sheltie puppy that barked all day but the collar worked. Eventually we only threatened to put the collar on and he would be quiet

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

Animals sense things alot better than humans do.

yes , they can sniff even if you have it stuck in the book.. thats how well they train those dogs ..

Much to the dissmay of Noam Chomsky, it appears that differnent non-human animals do have varying degrees of linguistical comprehension ability.\n\nChimps and Gorillas can be taught the ability to use sign language to some degree and they demonstrate the ability to understand spoken language. \n\nMany mammals can understand certain phrases and/or words, some relying more heavily on tones than others. Parrots of course can speak more clearly than any non-human animal and African Grey's have demonstrated actual understanding of some of the words spoken to them by picking out objects asked of them, such as a toy car, and even identifying the color. \n\nResearch has even shown that even the lowly rat can distinguish the difference between the sound patterns of different human languages. Of course it's unlikely they are able to understand any words to any degree but it does underscore the importance of communication and the fact that social animals are biologically hard wired for it.
