Babies don`t know to do this,they just do,I heard that newborns cry at birth to get air into their lungs for the first time,they don`t know how to make any type of reconizable sound other than crying.and you got to admit,it would be a little freaky if a baby came out of it`s mom singing or cursing!

Not if the water is a couple of feet above your chest.

No, but a person can pass out if he doesn't hum when my legs are around his face and I squeeze..\n\nWanna try it??

No. And here's why: \n\nThe falling rock will create the compressions and rarefactions of air that are the external stimulus for the auditory receptors. \n\nSound, however, is more than just those compressions and rarefactions; for there to be a perception of sound there must be an organism to hear it. \n\nThis organism, in order to be able to hear a sound, must have a functioning auditory system that receives the external stimulus capable of transducing the stimulus from physical into electrical energy and have the proper neurotransmitters that will turn that electrical energy into chemical energy able to stimulate neurons. It must have uninjured neurons in the proper places that will receive that chemical energy and transform it back into electrical energy and back to chemical energy using the proper neurotransmitters to stimulate the next neurons in the chain. The organism must have all these neurons going to the proper areas of the brain that will receive the energy and impute meaning onto it from prior experience. This prior experience is why we (as verbal humans) label as sound the sensations coming from the compressions and rarefactions that hit our ears and go up the chain. Other organisms will not label the sensation as sound, but will behave in other appropriate manners indicating that they heard the sound.\n\nSo without an organism, there can therefore be no sound.

When someone speaks above the water, the person underwater will hear it "twinkle" in exactly the same way and for the same reason as stars twinkle.\n\nSound undergoes various effects when it hits the surface of water including reflection, refraction and dispersion. the specifics of what happens depends on the volume of the sound, the surface shape of water (which tends to be irregular and turbulent, more so with a person under it) and the depth of water between surface and listener.\n\nthe listener will end up hearing a very distorted version of the speech with varying loudness, just like twinkling stars.\n\nnow will the listener be able to understand what is being said is a slightly different question. you can take it safely that if the speaker were reciting poetry, the listener will barely understand. but if the speaker were standing, with a horrified look on the face , point out far, and *screams* something that sounds to the underwater listener like sh--k! the listener will get the message :P

Astronauts can indeed cry in space. Tears run down your face because of gravity, but they don't need gravity to form. When the tears get big enough they simply break free of the eye and float around.

Yes you can. I have had them when i went swimming once and my friends can confirm this as they laughed at me :(.\n\nHiccups are a spasm of your diaphragm.\nWhen you inhale, it pulls down to help pull air into the lungs. When you exhale, it pushes up to help push air out of the lungs. But sometimes the diaphragm becomes irritated. When this happens, it pulls down in a jerky way, which makes you suck air into your throat suddenly. When the air rushing in hits your voice box, you're left with a big hiccup. I guess you could help relive hiccups if u dive deep in water as there will be more pressure trying to contract you rip cage which would reduce the amount of spasm and the holding of breath whilst underwater would probley help too.

It is possible to cry under water. However, it may not be noticable without some sort of goggles or mask.\n\nDuring the act of crying, an excess of water and salt (the same liquid that normally coats your eyeballs) in excreted (produced) in your tear ducts around your eyes. Outside the water, you notice the buildup as it falls down your face. However, in the water you do not experience the noticable tear because it is dissipated into the water almost as fast as it is made.\n\nBelieve it or not, your body actually attempts to sweat in hot water (ie, hot tubs, etc). However, you do not notice this sweat because it becomes part of the water as soon as it reaches the skin surface.  Tears under water act in the same way.

I don't think it's anything related to the body--such as what you stated of air pressure leaving the body.  I think it's just human nature to scream/yell when falling from a high level.  I guess you can say kinda like a reflex???  Like you eyes automaticall close when something comes close to it--so it protects the eye itself.  So, maybe the screaming is to where we may give that kind of "reflex" because when someone yells, it's in distress and hopes that the screaming/yelling will get attention from others for help.  I hope my answer made sense.  I never thought of this, so this is all from the top of my head.

Well, crying sound can be heard underwater. But, do tears appear when u cry underwater? No. thats because the pressure outside, that of the surrounding water, is greater than that of our tears. \n\n\nhm. I might be wrong. I dont know.

You are mistaken when you say that no other living being does. What you are asking is 'why do humans laugh and cry in a human fashion?'\n\nIt is thought that these activities are rooted in primitive communication that is built into us. The 'purpose' of laubhing and crying (like blushing) is to communicate to others of our kind our emotional state. And it isn't a willed communication except by really good actors. It's sort of like sneezing. Sneezing makes a sound secondary to it's purpose, but the result can communicate our status to others. So, while laughing and crying are built into us, they may have no other purpose than the one they are left with (not like sneezing which clears the nose). It's thought that such instinctual forms of communication are more honest than verbal communication is and has come to be an expression of fittness to breed simply because, as a result of an emotional response that is of a higher complexity than, say blinking, it shows a well developed and functional genome to a potential mate. Consider how off-putting it would be to see an emotionally neutral person, or one who just laughs or cries at meaningless moments.\n\nThe other idea is that it binds us into a community. That we laugh and cry in teams and groups. That is helps us in the way that wolves howling together helps them cohere as a pack.\n\nThis idea says that birds sing, monkeys hoot and pigeons coo simply as a group identity thing.

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.

no u cant,water will get in ur lungs and ur noses and then u'l drown! DUH! So dont try it cya!

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.

Yes, and I often do, I live in the country and no one can hear me. So if I feel the need to scream, I just scream. You should try it. It is a great way to relieve stress!
