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.
The sound itself would be something like a dull roar, DeForest says, because the sound waves coming at us would be composed of so many different frequencies. Imagine standing next to Niagara Falls all the time (it would actually be even louder — Niagara clocks in at around 90 decibels).
The answer might surprise you, as solar physicists estimate that the solar surface noise would be approximately 100dB by the time it reaches Earth! The enormity of the sun's surface paired with its capability of generating of tens of thousands of watts of sound energy per meter makes the sun astronomically loud.
By the way — the Sun does make actual sound. We just can't hear it because space is a vacuum, so the sound waves don't have a way of getting to us. But if we could hear the constant roar, it'd be pretty loud, even from here.
Yes, the sun makes very loud noise. But, since space is a very poor medium through which sound can travel and earth being about 93 million miles away, we cannot hear it with the naked ear.
Radio screams
Like the calm before a storm (but louder), they found that coronal mass ejections with shocks capable of unleashing radio storms are preceded by "screams" in radio waves as they barrel through the solar wind.
The Sun is immensely loud. The surface generates thousands to tens of thousands of watts of sound power for every square meter. That's something like 10x to 100x the power flux through the speakers at a rock concert, or out the front of a police siren.
Low-frequency background noise
Humans are unable to hear Earth's hum because it ranges between 2.9 and 4.5 Mhz. In general, humans can hear anything from 20 Hz to 20 kHz. So, this means that Earth's hum is about 10,000 times lower than what we are capable of hearing.
The planetary sounds we hear, are wavelike vibrations of air molecules occurring within the range of frequencies to which our ears are sensitive, according to the BBC (opens in new tab) .
OM is the collective sound of the Universe, the Primordial Sound.
However, the Moon is in space, and space is mostly a vacuum (there are always some atoms floating around, but they are VERY far apart and don't interact with one another). Thus there is no sound on the Moon.
What they found is surprising: The Sun is much quieter than other stars like it! While the Sun's median brightness variation is 0.07%, the other stars had a median of 0.36%, five times higher! That's even twice as much as the Sun's maximum variation of 0.2%.
No, there isn't sound in space.
This is because sound travels through the vibration of particles, and space is a vacuum. On Earth, sound mainly travels to your ears by way of vibrating air molecules, but in near-empty regions of space there are no (or very, very few) particles to vibrate – so no sound.
Next I'll say the first sound of the word. Listen: sun /sss/. /sss/ is the first sound in sun.
The Sun's “loudest pitch” is about 0.0033 Hertz (Hz) — some 6,000 times below the lowest tone audible to a human ear.
The entire Sun vibrates from a complex pattern of acoustical waves, much like a bell. If your eyes were sharp enough, you could see a bell's surface jiggle in complex patterns as the waves bounced around within it.
Astronaut Thomas Jones said it "carries a distinct odor of ozone, a faint acrid smell…a little like gunpowder, sulfurous." Tony Antonelli, another space-walker, said space "definitely has a smell that's different than anything else." A gentleman named Don Pettit was a bit more verbose on the topic: "Each time, when I ...
NASA has released a haunting audio clip of sound waves rippling out of a supermassive black hole, located 250 million light-years away. The black hole is at the center of the Perseus cluster of galaxies, and the acoustic waves coming from it have been transposed up 57 and 58 octaves so they're audible to human hearing.
This isn't a sound, it's a radio emission – but you could convert it to sound. The signal came back to us as a waveform, and then on the ground we converted it to a sound that you can listen to, and it is very, very loud. It is something called a heliospheric radio emission.
Any frequency below 20 Hz is called infrasound and any frequency above 20 kHz is called ultrasound. These are inaudible sounds. So, we cannot hear inaudible sounds, ultrasound, and infrasound.
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 godfather of radio technology decided that no sound ever dies. It just decays beyond the point that we can detect it with our ears.
The loudest sound in recorded history came from the volcanic eruption on the Indonesian island Krakatoa at 10.02 a.m. on August 27, 1883. The explosion caused two thirds of the island to collapse and formed tsunami waves as high as 46 m (151 ft) rocking ships as far away as South Africa.
“In fact, Jupiter is the second-noisiest body in the solar system, in terms of radio emissions, after the sun,” Byrne says. “Uranus and Neptune are the least noisy of these four giant planets.
Sperm Whale – 233 dB
The sperm whale is known to be the loudest animal on earth. It can produce a sound up to 233 decibels.
