Surely you all know a way to make the voice sound a lot sharper. And no, I'm not talking about a kick in a certain part of the male face.
Actually I mean something much simpler, as well as unisex: the helium aspiration. Many of you may have checked it out or seen someone do it, either in person or on television. Just suck up some helium from one of those balloons typical of fairs to make our voice sound much higher.
The problem is that this voice does not impose any respect. We would sound much more respectable with something else throaty, dark or demonicCall it what you want. That is precisely what he tells us Adam Savagein a video where he talks about the effects on the voice that inhaling would produce sulfur hexafluoride.
How does the voice change after inhaling gases?
As you know, the sound manifests in the form of waves, which travel through a medium, normallyfluid. In fact, you have surely heard that many science fiction movies make the mistake of reproducing the sound of explosions in space. This is a mistake because in the vacuum there is no means by which the sound waves can move, so it will not sound at all.
In the case of the voice something similar happens. Our vocal chords vibrate, producing waves that will travel through the air. Now, well, what happens if we change the medium?
The helium is six times less dense than air, so these waves have less difficulty moving and can travel more quickly, giving rise to sounds sharper.
On the other hand the sulfur hexafluoride is six times denser than air, so the waves move more slowly and the sound be more serious.
Why shouldn't we do this experiment at home?
As Adam says in the video, it is not a good idea to do this at home; but why?
Neither of these two gases is considered toxic, but that does not mean that it is harmless to our health. When inhaled, they replace the air in our lungsAs you know, this air includesoxygen, essential for the proper functioning of our body.
Neither helium nor sulfur hexafluoride contain oxygen, so they cannot be used by our cells. So if the process takes too long, it could cause suffocation death. Both can be dangerous, although the second is the worst, as it is more easily retained in the lungs.
As proof, if you've ever done the helium trick several times in a row you may have experienced a small dizziness, result of the low supply of oxygen in the brain.
As you can see, the best thing is not to risk it. If you want to see your voice become that of a smurf or that of Darth Vader, there are a lot of computer programs that modulate the voice until it is unrecognizable. Much better than jeopardizing health, don't you think?
