live sound collage broadcasts

Sonification, the transformation of data into sound, is a favorite topic of Special Collections.

Helioseismology is the study of the interior of the Sun from observations of the vibrations of its surface.  The Sun is nearly opaque to electromagnetic energy, the means by which scientists have traditionally mapped bodies in space  On the other hand, the Sun is essentially transparent to acoustic waves.

As the Sun is constantly vibrating, acoustic waves trapped within the sun cause solar oscillations that are measurable upon it’s surface.

Sonfication of data collected through the study of helioseismology is the topic of tonight’s program.

Data gathered by the following organizations:

NASA Solar Dynamics Observatory
National Solar Observatory
Stanford Solar Observatory Group
University of Michigan Solar and Heliospheric Research Group
National Optical Astronomy Observatory
HAARP Induction Magnetometer
