This article has sound clips of stellar seismology readings from the COROT telescope for several stars, including the Sun.

If you listen closely to the sounds of each star - by clicking on the media in this page - you'll hear a regular repeating pattern.

These indicate that the entire star is pulsating.

You'll also note that the sound of one star is very slightly different to the other. That's because the sound they make depends on their age, size and chemical composition.
