Pardon? <img src="/images/icons/tongue.gif" /><br /><br /><br /><br /><br />I believe you are hearing the sound of air being spurted into the EVA suit - I think. I know it sounds like he's banging a hammer <img src="/images/icons/smile.gif" />

I guess the audio feed makes it sound a bit mechanical.

Space does have sound. Think about those cosmic explosions!!<br /><br /><b>This Is Only The Beginning of A New Adventure!!!!</b> <div class="Discussion_UserSignature"> <font size="2" color="#14ea50"><strong><font size="1">We are born.  We live.  We experiment.  We rot.  We die.  and the whole process starts all over again!  Imagine That!</font><br /><br /><br /><img id="6e5c6b4c-0657-47dd-9476-1fbb47938264" style="width:176px;height:247px" src="http://sitelife.space.com/ver1.0/Content/images/store/14/4/6e5c6b4c-0657-47dd-9476-1fbb47938264.Large.jpg" alt="blog post photo" width="276" height="440" /><br /></strong></font> </div>

Low pitched sounds (think sub-audible) propagate in space, but the path loss is very high even at 30 hertz. Neil

Say what?<br />Sound cannot travel through a vacuum. If you mean sound traving inside the shuttle , where there is air, while travelling through space, then ok.

Maybe the tools knocking against the ISS vibrated through the tool and into the space suit which produced a sound?

i think the only sound in space is just the regular background noise

<Maybe the tools knocking against the ISS vibrated through the tool and into the space suit which produced a sound?><br /><br />quite rite. as sound is nothing more then vibrations. the sound will not travel through open space but will travel through the tool, suit and the air inside of the suit. <br /><br />A simple test of this can be done by suspending a speeker in a glass enclosure and submitting it to a vacume. you will still here sounds but not at the volume as if the speeker were out in the open. the sounds you hear are the vibrations of the mounts holding the speeker traveling to the out side of the vacume.<br /><br />gawin

Hello <img src="/images/icons/laugh.gif" /><br /><br />I was told by someone that there is no sound in space is this true?

as far as i know none that would be discernable by human hearing. unless maybe you were in a dense enough gaseous medium or cloud for sound to travel through.<br /><br />this raises a good question, though. how dense must something be for sound to propagate through? <br /><br />

Sound is created by waves of vibrations of atoms/molecules.<br /><br />Where there are no atoms to vibrate, there are no sound waves.<br /><br />Sound is actually kinetic energy being passed from atom to atom, and our ears can detect it.

Like they say, in space no one can hear you scream.<br /><br /><br />Especially with an alien face hugger psuedo-ovu-palp rammmed down your throat implanting a little tentacly bundle of vicious teeth and bad attitude.<br /><br /><br /><img src="/images/icons/tongue.gif" /><br /><br /> <div class="Discussion_UserSignature"> <p><font color="#ff0000"><strong>TPTB went to Dallas and all I got was Plucked !!</strong></font></p><p><font color="#339966"><strong>So many people, so few recipes !!</strong></font></p><p><font color="#0000ff"><strong>Let's clean up this stinkhole !!</strong></font> </p> </div>

<blockquote><font class="small">In reply to:</font><hr /><p>I was told by someone that there is no sound in space is this true?<p><hr /></p></p></blockquote><br /><br />There is sound in space, but it's not the kind you're used to.<br /><br />Technically speaking, any pressure wave is sound, and there are definitely pressure waves in space. However, many of these pressure waves have wavelengths miles or even light years in legnth. Your eardrum can only vibrate a few millimeters, so it's not going to pick that up. <img src="/images/icons/wink.gif" /><br /><br />For everyday practical purposes, there is no sound in space; the medium of space is far too rarified (the opposite of dense) to transmit sound. However, for scientific purposes there is sound in space, and researchers do a lot of work observing the propagation of pressure waves through the interstellar medium. <div class="Discussion_UserSignature"> <p> </p><p><font color="#666699"><em>"People assume that time is a strict progression of cause to effect, but actually from a non-linear, non-subjective viewpoint it's more like a big ball of wibbly wobbly . . . timey wimey . . . stuff."</em>  -- The Tenth Doctor, "Blink"</font></p> </div>

Humans hear sounds between 30 hertz and 20,000 hertz. Our hearing is most sensitive in the range of hundreds of hertz and we perceive pitch changes best in the hundreds of hertz range. if sub- audible sound is very loud we can feel the vibrations rather than hear them. At a millionth of one hertz, we would use a calander to notice the pressure change. Still lower frequencies are thought to propagate accross the galaxy, but they are difficult to detect with present technology, except when they are extremely loud. Neil
