No, you cannot hear any sounds in near-empty regions of space. Sound travels through the vibration of atoms and molecules in a medium (such as air or water). In space, where there is no air, sound has no way to travel.
In space, no one can hear you scream. This is because there is no air in space – it is a vacuum. Sound waves cannot travel through a vacuum.
NASA Has Captured 'Actual Sound' in Space and It's Honestly Terrifying. Vice. Start a conversation, not a fire.
The space agency used instruments on several probes (like Voyager and HAWKEYE) to record these waves. Then they put them together into a recording of a sound for all of us to hear. The result is a sound that is (frighteningly) akin to what you would expect to hear echoing as you sink into a black abyss.
In contrast to the swift-traveling vibrations in electrical and magnetic fields that we call light, the sounds of the universe are carried by vibrations in spacetime called gravitational waves.
When astronauts are out in space, they can whistle, talk, or even yell inside their own spacesuit, but the other astronauts would not hear the noise. In fact, the middle of space is very quiet. Sound travels in waves, and it moves at different speeds through air or water or other materials.
The universe speaks to us all the time. We don't always recognize the messages or realizations because the universe speaks through experience. In Vedic wisdom, a lot of attention is placed on the importance of becoming more aware of your life experiences.

The loudest sound in the universe definitely comes from black hole mergers. In this case the “sound” comes out in gravitational waves and not ordinary sound waves.
Black holes are absolutely silent, as they are creatures of pure gravity. But while black holes produce no sound of their own, they can generate sound waves in their environment.
Sound waves require a medium to travel from their source to our ears, like air or water. The vastness of space is almost empty, which means that even if we had space probes travelling through the cosmos, they wouldn't be able to capture audible frequencies with standard microphones.
Nothing like it has ever been seen before, but it was captured accidentally by NASA's Hubble Space Telescope. This is an artist's impression of a runaway supermassive black hole that was ejected from its host galaxy as a result of a tussle between it and two other black holes.
The Universe is thought to consist of three types of substance: normal matter, 'dark matter' and 'dark energy'. Normal matter consists of the atoms that make up stars, planets, human beings and every other visible object in the Universe.
Scientists now consider it unlikely the universe has an end – a region where the galaxies stop or where there would be a barrier of some kind marking the end of space. But nobody knows for sure.
Experts may not know whether space is infinite, but they do know that the universe is growing. It's been expanding since the Big Bang itself, about 13.8 billion years ago. And scientists recently found that it may be doing so at a faster pace than they previously thought.
Practically, we cannot even imagine thinking of the end of space. It is a void where the multiverses lie. Our universe alone is expanding in every direction and covering billions of kilometres within seconds. There is infinite space where such universes roam and there is actually no end.
The Sun does indeed generate sound, in the form of pressure waves. These are produced by huge pockets of hot gas that rise from deep within the Sun, travelling at hundreds of thousands of miles per hour to eventually break through the solar surface.
Sound is a mecanical wave, which means that it needs substance to travel through, such as air or water. In space, there is no air, so sound has nothing to travel through. If someone were to scream in space, the sound wouldn't even leave their mouths.
In 2004, Guinness World Records certified the anechoic chamber at Orfield Laboratories as the quietest place on Earth, with an ambient sound level of –9.4 decibels A-weighted.
Don't let the name fool you: a black hole is anything but empty space. Rather, it is a great amount of matter packed into a very small area - think of a star ten times more massive than the Sun squeezed into a sphere approximately the diameter of New York City.
Stellar black holes are very cold: they have a temperature of nearly absolute zero – which is zero Kelvin, or −273.15 degrees Celsius. Supermassive black holes are even colder.
The viral audio, to be clear, is not a recording: it has been produced by 'sonifying' data taken from NASA's Chandra X-ray Observatory (another space telescope). The audio produced was originally 57 octaves below middle C, which meant the frequency had to be raised 'quadrillions' of times to be heard by human ears.
The universe (observable or otherwise) has no boundary in the physical sense. This is one of the most commonly seen misunderstandings about physical cosmology. The universe is not a bubble expanding into a preexisting volume. The universe exists everywhere and and is approximately the same everywhere.
There's a limit to how much of the universe we can see. The observable universe is finite in that it hasn't existed forever. It extends 46 billion light years in every direction from us. (While our universe is 13.8 billion years old, the observable universe reaches further since the universe is expanding).
