That question refers to Helioseismology, Dear Prof. Nancy Ann Watanabe.

I unquote a few worlds from Wikipedia:

https://en.wikipedia.org/wiki/Helioseismology

"...Helioseismology, a term coined by Douglas Gough, is the study of the structure and dynamics of the Sun through its oscillations. These are principally caused by sound waves that are continuously driven and damped by convection near the Sun's surface...".

Also some explanations in:

Perhaps you should read the following two papers:

1- The Use of Sun, Quiet Sky and Earth Noise Measurements for Determining System Parameters, with Error Analysis www.janbob.com/electron/Sn_MUD3A_3.pdf · PDF file

2- Chapter 10 ANTENNA MEASUREMENT USING SUN NOISE

Noisy. Considering the electronic point of view, it generates a thermal noise or Gaussian white noise.

Thank you very much for your answer and two links, which I opened and thus saw a whole new world of information about the sun, including that it has millions of musical notes inside of it! I learned that this type of study commenced in the 1960s and that helioseismology is a relatively new area of scientific research. I even read the study suggestions for teachers, kindergarten through the third grade, complete with classroom experiments designed to help the children to understand what a few of the sounds inside of the sun are like, how they "operate" or "function," so to speak. And the Wikipedia article gives a detailed explanation of the physical characteristics of the sun, lots of background information, and a list of academic disciplines devoted to study of the sun and the cosmos of the solar system, as well as a few statements that point toward the universe of stars.

One statement that puzzles me is to the effect that, although scientists are trying to understand the "heartbeat" of the sun, it will not be possible for anybody actually to hear any sounds emanating from the sun because "there is no air between Earth and the sun." Suddenly, I realize that space has no air, and therefore, must be a vacuum. Given all of the discussions on other Research Gate threads about "dark matter," "dark energy," and, of course, the now outdated "ether," I had forgotten that space is, in essence, "sound-proof"!

But one of the experiments described in the Stanford University tips for grade school teachers demonstrates that the definition of "sound" is not only in terms of what may be perceived and heard by the ears of humans and other beings on Earth. "Sound" is, in scientific reality's terms, vibrations. So the sun's sound may be understood by school children who observe an object as it is being moved by vibrations caused by sounds. Part of the dynamics happening inside of the sun are made of these movements caused by emitted sounds as subatomic neutrinos collide and chain reactions are triggered, which, in turn, make a solar "symphony"!

But then, there is also the phenomenon of solar wind. So why can sound, including solar symphonies, not be transmitted to Earth by solar wind, I am wondering.

My pleasure, Dear Prof. Nancy Ann Watanabe. I guess that the idea of a vacuum space is given by the idea of a place with very low pressure, that is, P ---> 0. As it is taken in the field of surface physics for instance.

Therefore yes, sound cannot propagate in a vacuum, but we have cosmic rays (particles) arriving from the sun (and not only electromagnetic fields E and H), so the space in between the 2 (sun - earth) is not completely empty.

Pedro L. Contreras E. ,

Thank you for the link, which contrasts the vacuum that makes up interplanetary, interstellar, and intergalactic space to a household vacuum cleaner, because the actual cause for the virtual emptiness of space is gravitational attraction, which is powered by massive bodies that pull particles and essentially clear space. Only cosmic rays, which travel at less than the speed of light, occupy space, but only very sparsely, one particle per cubic kilometer, or a similar ratio. Evidently, the universe is uniform, in terms of space and cosmic rays. The Live Science article says that cosmic rays arrive at Earth from our sun and also from other galaxies?! It seems, therefore, that cosmic radiation represents the most powerful type of particle entity in the entire universe. So when scientists and technologists invented the nuclear fission reactor, they created yet another source of cosmic radiation in the form of exhausted nuclear fission waste, which can absolutely never be destroyed or defused by nuclear physicists or chemists? And now, nuclear physicists are aiming to produce nuclear fusion reactors in England and China. And so, scientists have been learning to reproduce nuclear fission and nuclear fusion processes that are taking place on a megatonic scale in the sun, between the rigid core and the atmospheric outer layer of photons. And yet, the sun is gradually decreasing in size, in one respect, but as its hydrogen fuel is exhausted, or spent, is its cosmic radiation being ejected, analogous to the way a nuclear fission reactor on Earth ejects radioactive waste?

The spectrum of the sun is not weight noise.

It is a bandpass signal.

Light is part of this signal.

Dear Prof. Nancy Ann Watanabe,

I found some records with different sound waves coming from the Sun, Sounds of the Solar Wind

As with colouring of space data (or any scientific data) one starts from parameters, and translates these into visualised colours.

You can take any time series and make it audible, by transposing it into the audible frequency spectrum.

Now there has been genuine art addressing this issue of representation of physical space parameters into the space of human senses (visual, audio, tactile?, etc). Music is particularly important in visual story telling, and it is in any science fiction movie or space exploration movie.

One can therefore answer that the sun can be listened to. Take the time series s(t) of temperature at on point x of the sun surface, you can make it audible. Add a few for positions x1, x2...xN, then you have an orchestra of instrument s1, s2, ...sN

Dear all, I think all moving objects have sound. Noisy or quiet depends on the separation distance and the interval of resolution/sensitivity of the receptor (our ears for exemple). My Regards

The heliophysicist Craig DeForest, of the Southwest Research Institute's Department of Space Studies; says : “The sun is extraordinarily loud,”

What Would the Sun Sound Like If We Could Hear It On Earth ...

https://www.discovermagazine.com › the-sciences › what-...

“The sun is extraordinarily loud,” says heliophysicist Craig DeForest, of the Southwest Research Institute's Department of Space Studies.

How loud would the sun be measured on Earth if its soundwaves could propagate through space? The answer might surprise you, as solar physicists estimate that the solar surface noise would be approximately 100dB by the time it reaches Earth!

If space were replaced with air and we could hear the Sun, it would be incredibly noisy – the output of the Sun is equivalent to 10 million keys, or notes, of a piano. ... Throwing out an energy of 383 yottawatts per second, we get a translation of 290 decibels which makes for a very, very loud Sun indeed.

the sun does make noise. The noise doesn't travel into outer space, but it's there.

The sun does vibrate and it is possible to measure. However it is very low frequnecy, so it would not be audible. For demonstration the vibration data from SOHO (?) has been pitched up to audible frequencies and can be listened to.

I guess the turbulent noise from the activity also would be audible if we had a mic there, immensely loud I´d guess.

The sun generate sound, in the form of pressure waves.

In addition to the previous answer, you may refer to the thermal noise. Photons coming from the sun vibrate in typical thermal agitation.
