what becomes the sound energy in space emanating from Sun or other stars.?

Answer 1

Essentially, it heats up the atoms & molecules of the sun & it's atmosphere, then the heat radiates into space.

Answer 2

Hi. The upper layers of the Sun are loud beyond comprehension. I read once that the bomb detonated over Hiroshima had an SPL of 250 or so dB. And that was microscopic compared to the sound energy of the Sun's atmosphere. The sound needs to have a medium to travel through, though. As the upper layers transition into vacuum I would think that last bit of energy laden particles would try to overcome gravity, fail, and the particles would fall back into the atmosphere.

Answer 3

Actually, there are plenty of "acoustic waves" in the interstellar medium. These are basically sound waves, although the medium is very diffuse and you wouldn't hear anything with your ears. Also, the wavelength and frequency of these waves is long compared to sound in our atmosphere, because the mean-free-path between molecules colliding with other molecules is large, so the wavelengths cannot be short.

Acoustic waves do not usually have much energy compared to other sources of energy in the interstellar medium and so are not important to the dynamics. If a lot of energy is put into mechanical motion of the gas, it usually winds up in a non-linear shock rather than acoustic waves.

The one major exception to this is acoustic waves in the first few thousand years of the Universe. These wave were powered by primordial inhomogeneities, and became the basis for all the subsequent structure in the Universe---galaxies and clusters of galaxies. These waves can be seen as anisotropies in the Cosmic Microwave Background.

Answer 4

Sound energy is transmitted by a longitudinal pressure wave travelling through a medium. As space is a vacuum, there is no sound energy travelling through space. It's completely silent! The sound energy coming from a star is just part of its overall kinetic energy.

Answer 5

There is no sound energy is the space around any stars.

Answer 6

It just keep flowing along.
