With a shell, cup, or anything else, you can't actually hear the ocean right? Isn't that just the blood flow? Or is there anyway to hear the ocean when you're far away from it?

Yeah, the sound in the shell is the echo of the blood flow. The only way I know of to hear the ocean from far away is a recording.

Never mind. No question is a stupid question as long as u learn from it. Here's my explanation. Where does sound come from? Sound is actually produced by vibration. As long as it has vibration, it produces sound, no matter how loud or how soft. Even molecules in a solid produces sound because it vibrates, but we can't hear the sound because it is out of our hearing range. Well, as you asked, when a tree falls, it actually vibrates, hence, sound is actuallly produced although we can't hear it. For your second question, IF, lets say you are in the woods and happen to see the tree fall, and you can hear the sound of the fall of the tree. Your question was, how on earth you heard that sound, right? Here's the explanation. When the tree falls, it vibrates. When it vibrates, energy is transfered to the air. The air molecule will then vibrate and the so-called sound wave will then be transmitted into your ears.

The subtle differences in atmospheric pressure at ground level will not contribute to changes in sound waves. Although this is a viable concept because sound is a wave and the atmospheric pressure will change its progression through that environment, thus changing the sound and if our ear is in the same pressure the interaction upon our ear as well.\n\nI suspect other noises act as a source to drown out the airport noise at certain time and not at others. For example, in a crowded mall ever notice how hard it is to carry on a simple conversation with someone next to you, however in a quiet room you can hear you dog let gas go! Sound waves combat other sound waves, and the strongest will win. Strongest being in most cases the one closest to you.

I had an out of body experience.  I floated above my body and watched my friends try to wake me up.  They were yelling at me to breathe and I was alright after a short time.  When I came down, I realized what a low existence we live in.  Reality is a very low existence.  It's hard to put in words.....)(

Every drop contributes to make an ocean. Its not a lost cause. People will take u seriously, atleast the ones who asked, even if they dont show. You have impacted their minds n thinking in a way.\nEven I'm not crazy 4 points. Will get there answering only what I know n whats required. Lets do it.

DB: This is Earth and Sky. A listener wants to know, "Can people actually shatter glass by singing a particular note?"\n\nJB: To understand the answer to this, you need to know that every object has a resonant frequency -- that's the natural frequency at which an object vibrates. If you could run a damp finger along the rim of a glass, you might hear a faint, ghostly hum -- the resonant frequency of the glass. To shatter the glass, the singer's voice has to be able to match that frequency.\n\nDB: Also, the singer has to sing very loudly. A jackhammer operates at a loudness of about 90 decibels. The human threshold for pain comes at about 120 decibels. To shatter a glass, a singer has to produce a note with an ear-splitting intensity of about 135 decibels.\n\nJB: And the singer also needs to hold that note for at least two to three seconds -- for the vibration to build up enough to cause the glass to shatter. It helps to have the right kind of glass, too -- a large one -- with thin, nearly vertical sides. In the late '70s, laboratory experiments with a professional soprano and a trumpet player showed that neither could shatter glass. The famed tenor, Enrico Caruso, was said to be able to do it -- but his wife denied it. \n\nDB: So there are physical conditions under which a human voice should be able to break a glass. But it's improbable that an unamplified human voice could actually do it. With thanks to the National Science Foundation, we're Block and Byrd for Earth and Sky.\nAuthor(s): Marc Airhart

my mom is a nurse and I asked her that once and she said.. its a myth... furthermore.. size is NOT important to a female's satisfaction during intercourse.. for anatomical reasons- a woman's anatomy is designed so that only the outer surface of the vagina has "sensors" to respond to stimulation... the argument "the motion of the ocean" is very legitamate..\n\nIm pleased to be the one to solve two myths for you today.. cheers...\n\ncertifiedtarot... its not fun for me .. im white :'(..\n\nlol

sounds are waves, which travel through a medium.  In this case, the medium is air.  \n\nVariations in density distort the waves (which is why things sound different underwater).  Wind causes these density fluccuations in air.  Therefore, it can affect the sound you hear.

I am the first person to answer you question because the answer is not answerable.  It is a feeling.  Stand on the beach, look out at the ocean, watch the birds, listen to the crashing waves.  If you feel it, you know.  If you don't... then the beach is nothing special.

Under what conditions?\n\nI recall seeing an article about a hotel in the Florida Keys that has made a series of underwater "bungaloes" that guests need to SCUBA dive down to, and out of.  Looks like it would be interesting.  And there are deep-sea researchers that live at depth for some time.\n\nBut either one requires a great deal of support at this time, since none of them could be considered self-sufficient.  Perhaps in the future?

The sound will reach the car in front of you.  Although it may seem as though it would not, considering that you are already traveling at the speed of sound, therefore you may think the sound waves go as the same speed as your car therefore not traveling any faster than you are and not getting to the car in front of you.  However, this is not the case.  This can be explained using Einstein's theory of relativity.  Einstein describes "frames of reference" and in your frame of reference, you are not moving; everything else is moving.  Everything in your car is stationary relative to everything else, this is why you don't feel like you're moving, and if you throw a book sideways, it doesn't fly backwards with the speed your vehicle is moving, this is because the car, yourself, and the book are all moving with the same speed your car is moving. They are all stationary relative to each other. When the sound waves are created, they move in all directions at the speed of sound (331 m/s), so in your frame of reference, they would be moving at 331 m/s away from the car in all directions.  This means from the frame of reference of a person standing outside of your car, the sound waves would actually appear to be moving at twice the speed of sound.  This is just like if you threw a ball forward out from the car at 15 m/s, it would appear to an outsider to be moving at that speed plus the speed of sound(well in a vacuum anyway, or before air resistance took over) To use a better example of these frames of reference, you know that the earth is rotating.  It is rotating at 1070 mi/hr at the equator, yet it seems not to be moving at all, it is our frame of reference when we are standing 'still.' the speed of sound is no different traveling in different directions on the earth because of this rotation.\n\nand yes, he would probably give you the finger. I mean, he is going at the speed of sound, how impatient are you?

because the sound reverberates in your skull, and with the water acting as a sound proofing, there is very little distraction noise-wise and the whispering becomes clear.  Basically you are hearing from the inside out.  Now when you come out of the water, there is water in your ears, and you no longer have the insulation of the water around your head.  That, combined with the noise of sitting up, the water splashing around you, the ambient noise from your surroundings, causes you to not recieve the soundwaves, which are now outside of your head and "mixing" with the rest of the noise.\n\nGet it?

There is a condition where you can hear your pulse in your ears, but the Ent should have found that.  The next thing that comes to mind is hearing your carotid pulse in your neck.  How old are you?  Middle -aged or more?  Talk to your regular doctor, ask hm to check your neck veins.  As we get older, we can have narrowing in the carotid arteries in the neck...this causes a 'MURMUR" or whooshing sound.  If that is ok, then ignore it.  sometimes this happens and there just is no reason found.

I posted a very similar question here not long ago (minus the farting bit)!!\nI asked if I was the only one that thought it was all 'tosh'\nI should have actually asked about ozone layers etc!\nHowever I did get a couple of very interesting answers that agreed with me, I hope you get the same response, I am sure it is all hogwash and I was very pleased to hear from others that were on the same wave length.

I have zero knowledge of the full contents of the earth's oceans, but i'm going to throw out my opinion here that while almost anything is possible, it is improbable that mermaids truly exist in the form we see them in fairy tales.  They are represented as human formed/fish tailed beings, with human upper bodies, lungs, arms, etc...meaning they would be breathing air, not processing oxygen from water.  In spite of the size of the oceans, mermaids leaping from the water to suck in some air would eventually be spotted, certainly at a frequency greater than once every 500 years.

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.

When healthy people are over-tired or over-heated, they also may hear a pulse beat in the ear. Remember that the carotid arteries, which are big blood vessels carrying blood from your heart to your brain, run on either side of your neck, close to your ears. \n\nBecause you have some hearing loss, you may not hear external sounds around you as well, which make you more aware of "inner" noise, such as your pulse. A hearing aid could make a difference for you. \n\nIn addition, if your nose is very congested, pressure can build up in your Eustachian tubes, which connect the back of the nose and throat to the ears. Taking a decongestant or blowing your nose often might decrease the intensity of the pulse.  http://healthlink.mcw.edu/article/901226039.html
