This video shows a computer emulation of stellar seismology in different stars.
The surface of a star usually oscillates, and this oscillation can be tranformed into an audible sound wave.

Stellar seismology is the study of the propagation of these wave oscillations in the stars, particularly acoustic pressure waves.

Star pressure waves are generated in the convection zone near the surface, then the acoustic waves are transmitted to the outer photosphere of the star.
The oscillations are detectable on images of the Sun, or by measuring the doppler shift of photospheric absorption lines of a star.
