Next up, our neighbouring planet Venus: that roasting hot hell-hole of a world not even vaguely conducive to human existence, with a surface temperature hot enough to melt lead, a crushingly high pressure (think 900m under the sea!) and thoroughly poisonous, largely carbon dioxide atmosphere (aprox. 70 x the density of Earth’s – all thick and soupy) On this basis your lungs would be crushed and you wouldn’t be able to shout, scream, yell or even sing no matter how much you might like to, and you certainly wouldn’t be having a chat since you wouldn’t be able to speak. All these delights coupled up nicely with a choking cover of sulphuric acid clouds. If you survived long enough, due to Venus’s retrograde orbit you could enjoy the curious pleasure of watching the sun rise – in the west and set in the east! As you probably wouldn’t survive you might still have just enough time to see the Venutian night sky. You wouldn’t see any stars but it would be suitably dark and black. If on the other hand your untimely demise happened to occur during the day you would be able to enjoy an orangy-red sky for a few seconds – the result of the sunlight being scattered around by those deadly carbon dioxide molecules. Returning to your vocalisations, should you be lucky enough to try having any, the high atmospheric density would lead to much slower vibrations of your long-suffering vocal cords so your vocalisations would sound very deep bass-toned. However, since the sound waves you produce, if you’re really, really lucky, move through Venus’s atmosphere much quicker than they would in Earth’s so you would also be speaking in a decidedly squawky, squeaky fashion! Not great for your final yell of protest at your pending demise on Venus!

Standing outside on Mars with a view to taking a refreshing breath of fresh freezing cold Martian air whilst chatting about the stupendous view of neighbouring planet Jupiter might leave you wishing your body contained something else other than blood – seeing as it would repay you for the ill-thought up idea of going outside without a space suit by boiling you to death. You wouldn’t have too much time to converse about the dumb-founding beauty of the view of Jupiter as having been dumb enough to go outside in the first place and boil your blood you won’t last a matter of seconds anyway. This slightly pressing problem might possibly give you the completely understandable desire to have a good old scream before you die but even that isn’t going to go to plan. Nobody will hear you. Not least because most people wouldn’t be dumb enough to go outside on the Red Planet in the first place. But also, because the Martian atmosphere consists almost completely of carbon ­dioxide – 95% to be precise, and it does an awesome job of absorbing vibrations – such as those produced by your vocal cords. So, not only is screaming a waste of the precious time you have left, but if you thought you could accompany your ill-fated visit for fresh air on Mars with the ear-shattering sounds of your favourite music blasting out of that old ghetto blaster you brought with you from Earth – luck’s out. Krank up that volume all you like (but be quick – remember you have only seconds to live!) but it will still be little more than a distant tinkle of sound when you’re 10 metres away. Should you wish to sing along to it, the Martian air slows sound waves down to such an extent that you will produce nothing more than a hoarse, deep-toned croak.

What Would Your Voice Sound Like On Other Moons and Planets?

 

Scream, shout and yell into the vast and infinite realms of space in the ever-optimistic hope that someone or something might just hear you and do you think anyone or anything will cheerily respond to you? Maybe. But it always depends on whether anyone or anything can hear you!

originalCShouting your head off on another world doesn’t guarantee the noisy and well-loved sound of your terran-based vocal cords will resound in quite the same way in the atmospheres of other worlds comfortably nestled amongst the stars.

 

On the cosy home world of Earth sound whizzes happily and easily through the atmosphere thanks to a distinct lack of vibrations being absorbed by our gassy air. This is one of the particularly pleasing results of lots of nitrogen and just a tiny scrap of molecules of the carbon dioxide variety. The other handy bonus is of course that we can breathe…. Minor detail but worth a mention Be right back

Things start to get a little bit weird however, should you be posturing and screaming on worlds that are clearly not Earth. Different worlds, different atmospheric densities and all that scientific, technical stuff. Disappointed smile

Most of us are probably at least vaguely aware, (don’t worry if you’re not, maybe for the best!), that “in space no-one can hear you scream!) This detail tends to apply too, on the majority of worlds in space. By and large they don’t have any atmospheres at all, and the ones that do have ridiculously thin and weedy atmospheres that contain so few gases that it would be impossible for them to carry even a single stingy little sound wave. Not that this would worry you overly much as you wouldn’t be able to breathe anyway and therefore wouldn’t be alive to be annoyed by it. If you happened to be a planetary native of that particular world specially adapted to create vocalisations on a super-sonic sound scale, of the nature that would shatter lesser worlds into a zillion pieces then you might just about manage to make yourself heard in some shape or form. Although it would most probably end up sounding something more like a whispering little sound in the vast void of outer space. Winking smile
