Human can perceive sound in a range 20 Hz to 20 kHz. Even in the air, great that we are not able to hear all the sounds (e.g. bats communicate out of human ear range and at power over 140 decibel, about air jet just right near to you).
Definitely, the sound propagation is different in different media, even in the rare atmosphere. And the Space is not as much vacuum as it is usually thought to be. Neutrinos, dark matter? Just we cannot hear those sounds without transformation and cannot produce such frequencies.

So what is the sound frequency of the sun?

So what is the sound frequency of the sun?

Sun is vibrating at different frequencies, measured about 3 mHz for observation purposes.

40 days of the recording squeezed into seconds get the sound. These are vibrations of the matter moving inside the Sun, moving upwards and downwards, turbilating,  stirring on the surface.
Soundwaves, crashing through the plasma, create ripples in the Sun’s surface.

How is the sound detected and collected and is the sound that is heard a simulation or the actual sound of the sun?

The Sun’s internal and external plasma movement create the turbulence vibrations, which are captured by Solar and Heliospheric Observatory (SOHO). Data from SOHO, sonified by the Stanford Experimental Physics Lab.
Columns of gases swirl, rise and fall (same way as gases and liquids on Earth), these processes are being tracked inside the Sun.

When we hear sound in the air, we hear vibrations of turbulence (in audible range).
Under water detected sounds are also sped up in order to come to audible range.

Thanks for that info Tommy J.
