why human being has two ears and one mouth?


Answer:
Humans have two ears to allow for the use of sound to identify where and how far away something making the sound is. (Similar to echolocation, which humans can use, albeit somewhat crudely. More on that in a second.) Having two ears allows the same sound to enter in both but at slightly different times, and your brain uses the two different inputs to determine which direction the sound is coming from. As mentioned the prime example of this is echolocation, of which bats are the most popular example. They emit a sound which will bounce off of their prey and to their ears, and using the 'echo' from that they are able to determine where their prey is. Their ability is so honed that they can locate and capture tiny flying insects in while they're both in flight! The same theory of two different input points applies with having two eyes. Two eyes allows us to have 'depth perception'; the ability to judge how far away something is by sight. Close one eye and you'll find it much more difficult to tell how far away something truly is. Alternate opening and closing your eyes (so one is always open and one is always closed), and you'll see two different angles of whatever you're looking at. Your brain automatically merges these images so you only see one, and having these two combined images is what allows you to determine how far away something is. Same thing with sound, cover one ear and you will find that sound 'surrounds' you, but you'll find it much harder to tell where it's coming from unless you turn your head around until your open ear is facing the source of the noise.As for the one mouth, we really only need one. Just imagine how interesting a feast would be with two, though...
Because God want us to listen more and talk less.
to listen twice as much as you speak
because God wanted us to listen more than talk!
So that we will talk less and listen more.
two ears to hear all around him and one mouth because..one is all you need!
As opposed to what?Don't forget that the reason we have two ears and one mouth is basically because all vertebrates have such a bodyplan.Two ears give stereo sound and the ability to tell which direction a sound is coming from so we can use it to avoid predators and one mouth presumable because its the most efficient design. Some primitive (i use the word in its technical sense) have a 2 way digestion system rather than the in and out cycle we use.
Two ears are required to pinpoint the location of a sound in 3-D space, just as two eyes are required to pinpoint the position of an object in 3-D space.One mouth is required for entrance of food into the digestive system. There is no need for more than one.
Because our brains can handle more then our stomaches.
WHY? do you think we should have two mouths and one ear? what a silly question.
We have two ears - one on each side of our head. Having our ears placed this way helps us hear everything around us. If we only had one ear, we'd have to turn it toward the sounds we wanted to hear. We only need one mouth to allow us to eat.
2 ears so u can hear form both directions. one mouth cuz thats all u really need to talk and eat
imagine if humans had 2 mouths and 1 ear it will be more like punishment for that 1ear to transmit messages from the 2mouths.,worse if the 2 mouths are talking at the same time.
humans have 1mouth and 2 ears so that they can hear more and talk less.however, most people are doing the opposite.
TO TALK LESS AND LISTEN MORE
it tells the answer in Genesis throu Revealations.
You have to ears to give the precise location of where noise/ sound is coming from just like we have two eyes to enable us to have depth perception. we don't need 2months so nature has not evolved it!
Why is the mouth bilaterally symmetric and midline?
Becuase when god created us he wanted us to be good listener and not talk as much. also so you eat less than you hear
